Package ContentsConserve Insight Energy Use Monitor User Guide and Warranty Information1.5 meterCOindicatorcost mode icon unit for COmode icon1 Plug in the Conserve insightThe Conserve Insight screen willshow 0-1.0W until you plug a devicein. If your plugged-in device powerconsumption is below 1.0 watts, the0-1.0W screen will continue to appear.2 Plug any household device into theConserve insightThe screen will automatically displayhow many Pounds per year your devicecosts in its current operating mode. (Youdo not need to press anything on yourConserve Insight to view this screen.)3 Conserve insight buttonsWith your device plugged into theConserve Insight, press one of thecorresponding buttons to enter into thedesired mode. Pressing the CO2 orPound button more than once will switchbetween monthly and yearly readings,which are illustrated by the calendar iconin the bottom right corner of the display(30 for a month and 365 for a year).Estimated CO emissionsassociated with powering theconnected device for month or year1 energy Bar MonitorThe energy bar (located at the center-bottom of the display) tracks the amount of power being used by your connected device. At initial start-up of your Conserve Insight, the energy use is represented by one animated moving bar. After 45 minutes of use, your Conserve Insight will switch to a “Averaging Mode” and the energy use will be represented by three moving bars. Averaging Mode: Your Conserve Insightswitches to this mode after 45 minutes ofuse. Once in this mode, your ConserveInsight can more accurately calculate thecost of your attached device based onyour actual usage. The Conserve Insighttakes continuous readings of your deviceusage throughout the day, both while yourdevice is on and off. The readout will displaypower costs and environmental impact,averaged over time, based on your usage.2 Set rate ModeYour Conserve Insight is programmedwith a preset rate for the cost of electricitybased on the average for your geographicregion, but it may not match exactly to therate you are charged by your specific utilitycompany. In order to get a more accuratecost, you can enter your specific rate bylooking up the kWh rate shown on yourelectricity bill and then adjusting the EnergyUnit Cost per kWh on the Conserve Insight.Programming Set Rate Mode: Any timeduring operation, if the Pound button isheld down for longer than 3 seconds,your Conserve Insight will go into “SetRate Mode.” Once in this mode you canadjust the Energy Unit Cost per kWhto match that of your electricity bill.In “Set Rate Mode,” press the Watts buttonto increase your Energy Unit Cost per kWhand the CO2 button to decrease this cost.Holding down the Pound button for longer than 3 seconds will reset the Energy Unit Cost back to the factory default.To exit “Set Rate Mode,” pressthe Dollar button. If no buttons are pressed for 5 seconds, the display will automatically exit “Set Rate Mode.”3 Set CO2 Conversion Factor Mode(Continued)Enter your CO2 conversion factor in eitherpounds (lbs) CO2 per kilowatt hour, orkilograms (kg) CO2 per kilowatt hour,depending on the unit shown on the display.Change the value used for the CO2conversion factor when you arein “CO2 Conversion Factor Mode” bypressing the Watts button to increase thevalue and the CO2 button to decrease thevalue. Holding down the Dollar buttonfor longer than 3 seconds will reset the CO2conversion factor to the factory default.C hange the weight unit by pressing thePound button in “CO2 Conversion FactorMode.” The weight unit used to display CO2will flash. By pressing the Watts button orCO2 button you can change the weight unit.3 Set CO2 Conversion Factor ModeResidential electricity comes from severaldifferent sources, many of which generatepower by burning fossil fuels that emitCO2 into the atmosphere. Your ConserveInsight monitor comes with a preset CO2conversion factor based on averages foryour geographic region. In order to get amore accurate reading for your area, youcan enter the CO2 conversion factor usingdata from your electricity utility companyor the International Energy Agency (IEA).This will give a more accurate calculation forhow much CO2 emissions are associatedwith powering any connected device.Programming the CO2 Conversion Factor:Any time during operation, if the CO2 buttonis held down for longer than 3 seconds, yourConserve Insight monitor will go into “CO2Conversion Factor Mode.” Once in this mode,you can adjust the CO2 conversion factor.Press the Pound button twice to exit “CO2 Conversion Factor Mode.” If no buttons are pressed for 5 seconds, the display will automatically exit “CO2 Conversion Factor Mode.” L CD display screen3-button control- C O2 Button: EnvironmentalImpact (CO2 emitted to generatepower to run your device)- P ound Button: Cost Impact- W atts Button: Energy Consumption(Watts used by your device)1.5 meter tethered cord betweenoutlet and display unit- E asier viewing of the display unit. Allowsdisplay unit to be placed on a countertop.Easy-to-understand graphic iconsDisplays data in both monthlyand yearly predictionsI nstantaneous and Averagingmodes of usage calculation- I nstantaneous Mode: Values arecalculated using the power beingconsumed at that very moment. Goodfor showing cost and environmentalimpact of the connected devicein various operating modes.- A veraging Mode: Values are calculatedfrom an average of power consumedover the whole time the unit has beenplugged in. This mode allows for betterunderstanding of how connecteddevices affect your monthly bill andtheir true environmental impact.When I plug different devices into my Conserve Insight, after some time, the values on the screen don’t change as much and there is a strange icon above the meter bar. If you leave your Conserve Insight plugged into a wall outlet for more than 45 minutes, it swaps into an averaging mode. This mode is very helpful for getting more accurate estimates of the true cost of the connected device, but if you are just testing lots of different devices and their various operating modes, then the instantaneous mode is most helpful. To revert back to instantaneous mode, unplug the Conserve Insight from the wall outlet and plug it back in again. You will be in instantaneous mode for another 45 minutes. nOte: If you want the display to remain in instantaneous mode, you can do this by holding down the CO2 and Watts buttons simultaneously for 3 seconds. When you see the averaging icon flash, it means you have disabled the averaging function.A description of the different operating modes can be found in the Product Features section of this user guide.Sometimes when I plug devices intoConserve Insight, the screen shows “0-1.0Watt” and I don’t know what it means.Your Conserve Insight uses sensitiveelectronics to measure the amount of powerflowing to your connected device. Whenthe connected device is consuming a verysmall amount of electricity, it becomesvery difficult to distinguish between thepower being consumed and the electricalnoise found at all power outlets. To ensureaccurate readings, the Conserve Insightstops showing values below 1.0 wattsand displays the “0-1.0 Watt” screen.Specifications1.5 meter cord connecting display and socketElectrical Rating: 250V~/13A/50Hz/3250WMaximum Watts Displayed: 3250Maximum Pounds Displayed: 9999Safety informationimportant: Use indoors in a dry location.NOTE: This equipment has been tested and found to comply with the limitsfor a Class B digital device, pursuant to part 15 of the FCC Rules.

CO comes, in part, from the burning of fossil fuels, such as coal and gasoline, to generate electricity for use in our homes and to power our cars.The amount of CO in our atmosphere has increased over the past century, and the majority of scientists questioned in a recent international study agree that global temperatures have risen dramatically compared with levels from the 1800s, with human activity being a significant contributing factor. According to theInternational Energy Agency, a warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans.A good way to visualize CO is to imagine that 1kg of CO would fill up 1566 soda cans (0,35l), or a box 0,8m high, 0,8m wide and 0,8m deep.Belkin Conserve products can help you do your part to use energy wisely.use less, Save More, Feel Good.。

All rights reserved.1.4 A Dual H-Bridge Driver Compatible with 3.0 V LogicThe 34933 is a two channel H-Bridge driver aimed at the digital camera market. There are a variety of applications containing bipolar step motors and/or brush DC motors, such as Auto Focus control for the digital camera lens. The 34933 uses Freescale's proprietarySMARTMOS process to deliver a low-power device, with a maximum quiescent current of 100 μA for the motor drive supply and 400μA for the control logic supply.The 34933 V M supply operates from 2.0 V to 7.0 V using an internal charge pump, with independent control of each H-Bridge driver via the MCU (IN1A, IN1B, IN2A, IN2B). The 34933 has a low total R DS(on) of 1.0 Ω (max. at 25 °C). Shoot-through current protection is a built-in feature for the 34933 device.The 34933 has four operation modes: forward, reverse, brake, and tri-state (high-impedance). The 34933 employs a V CC detection circuit to sense when the logic supply switches to an off-state with a maximum current of 1.0 μA to extend battery life. The H-Bridge drivers can be independently pulse width modulated up to 200 kHz for speed/ torque and/or current control. Note that tri-state mode of H-Bridge drivers can occur when either V CC detect is low or the thermal detect is active.Features •Built-in 2-channel H-Bridge driver•H-Bridge operation voltage 2.0 V to 7.0 V •Max. load output current 1.0 A at T A = 25 °C•Low total R DS(ON) 0.8 Ω (typ), 1.0 Ω (max.) @ T A = 25 °C peak•Dual channel parallel driver, R DS(ON) 0.4 Ω (typ.). max.

VCC has an under-voltage threshold. If the supply voltage drops below the under-voltage threshold, the output power stage switches to a tri-state condition. When the supply voltage returns to a level that is above the threshold, the power stage automatically resumes normal operation according to the established condition of the input pins.LOGIC INPUT CONTROL (IN1A, IN1B, IN2A, AND IN2B)These logic input pins control each H-Bridge output. IN1A logic HIGH = OUT1A HIGH. However, if all inputs are HIGH, the output bridges are both tri-stated (refer to Table 4, Truth Table).H-BRIDGE OUTPUT (OUT1A, OUT1B, OUT2A, AND OUT2B)These pins provide connection to the outputs of each of the internal H-Bridges (See Figure 2, 34933 Simplified Internal Block Diagram).MOTOR DRIVE POWER SUPPLY (VM1 AND VM2)The VM pins carry the main supply voltage and current into the power sections of the IC. This supply then becomes controlled and/or modulated by the IC as it delivers the power to the loads attached between the output pins. All VM pins must be connected together on the Printed Circuit Board (PCB).CHARGE PUMP (CL AND CH)These two pins, the CL and CH, connect to the external bucket capacitors required by the internal charge pump. The typical value for the bucket capacitors is 0.1 μF.POWER GROUND (PGND)Power ground pins must be tied together on the PCB and connected to the common ground plane.LOGIC GROUND (EXPOSED PAD)The Exposed Pad is connected to the PCB Ground plane through vias by soldering. Note the primary purpose of the Exposed pad for 34933 is thermal heat dissipation.Therefore, adequate thermal vias should be included in the PCB design. The exposed pad should be connected to the common ground plane.VOLTAGE DETECTION AND THERMAL LIMIT DETECTIONThe 34933 has the VCC Low Voltage Detection (Vccdet) and the Thermal Detection (T DET ). VCC Low Voltage Detec-tion is designed to shutdown of IC functions when VCC becomes lower than specified voltage. Thermal Detection operates when the IC temperature exceeds specified valueand stop H-Bridge operation. Table 5 shows block status of 34933 by each condition. VCC is the control logic power supply for 34933. The system begins to operate when V CC > V CCDET (Typ. 2.2 V).Table 5.

The internal charge pump of this device is powered from the V CC supply. Therefore, care must be taken to ensure V CC is a high enough value to provide sufficient gate-source voltage for the high-side MOSFETs when V M > V CC (e.g., V M = 5.0 V, V CC = 3.0 V), in order to ensure full enhancement of the high-side MOSFET channels.The 34933 can be configured in several applications. The figure below shows the 34933 in a typical Slave Node Application.*1 - It is recommend to use low resistance copper PCB traces betweenVM & VCC ground and the PGND1/PGND2 pins.Figure 8. Typical Application34933Analog Integrated Circuit Device DataAnalog Integrated Circuit Device Data 34933PCB LAYOUTPCB LAYOUTWhen designing a printed circuit board (PCB), connect sufficient capacitance between power supplies (VM & VCC) and ground pins to ensure proper filtering from transients. For all high-current paths, use wide copper traces and theshortest possible distances. Note that capacitors should be placed as close to the 34933 as possible to maximize the filtering capability of each capacitor.Additionally, care must be taken to avoid CEMF spikes induced when inductive currents accumulate at the VM supply. The typical method of snubbing inductive spikes includes connecting a Zener diode or capacitor at the supplypin (VM).Analog Integrated Circuit Device Data34933PACKAGINGPACKAGE DIMENSIONSPACKAGINGPACKAGE DIMENSIONSPackage dimensions are provided in package drawings.
