Constant current operation mode (CC).2. Constant voltage operation mode (CV).3. Constant resistance operation mode (CR).4. Constant power operation mode (CW).4.1.1 Constant current operation mode(CC)As shown in the following figure, in the constant current mode, the electronic load consumes a constant current regardless of whether the input voltage changes. Please note that if the maximum current value of the source is less than the given constant current value, the load will not be guaranteed to be set to the given current value and the voltage to be tested will also be pulled down.4.1.1.1 Standard constant current modePress the I-SET button, the load shows "STANDARD CURR = xxxxxxxxA", showing the current value. Then you can press the number keys and decimal point keys on the panel and input the required constant current value from high to low, and p ress “Enter” to confirm that the load goes to the standard constant current mode.If the input status is ON, the upper right corner of the display panel shows "OFF". If you want to change the input state to “ON”, press the On / Off button, then "CC" or "Unreg" is displayed in the upper right corner of the display panel. The display "CC" indicates the expected constant current value; "Unreg" indicates thatthe load cannot be correctly adjusted to the given current value. Please check whether the source to be tested is properly connected and turned on or whether the source to be measured can output a preset current value.At this point, if you want to fine-tune the set current value, you canuse the rotary encoder in upper right corner, clockwise adjustment to increase, counterclockwise adjustment to reduce, please note that if the given current value has reached the maximum which is limited by load, the current value cannot be adjusted upwards. In this case, the current value is indicated on the lower right side of the display panel, and one of the numbers has a cursor, Indicating that the current fine fineness is one unit of the current position. If the user wishes to change the fineness of the adjustment, the rotary encoder can be pressed down.

High battery temperatures can cause the batteries to overcharge and very low battery temperatures can lead to undercharging.Set the dipswitch to enable the BVT Sensor ( ref ). Connect the BVT Sensor to the battery bank (Fig: 7.1)). Connect the RJ12 communications cable between the Programmable relay and the LCD MPPT.(Fig 4:1)The following screen appears on the MPPT screen for 1 minute.If the battery temperature increases this voltage decreases: ADJ -If the battery temperature decreases this voltage increases: ADJ +The difference between the MPPT battery voltage and the Sensor battery voltage.The correction is shown as either +/-.The Battery Temperature (BT) is then shown with the ADJ compensation.If the Battery Voltage Temperature is disconnected, the MPPT will revert back to stand alone readings.If a problem occurs with the BVT sensor the following error message is displayed on the MPPT screen and will display until the problem is fixed. Possible cause: BVT cable not connected or a bad cable connection.7.1 BVT Sensor Battery Connection 12V - 48V Battery Bank Fig 7:1PROGRAMMABLE RELAY SPECIFICATIONS 8.

These operate in CC or CV mode within a wide operating range limited only by the output power.The operating area of each power supply is determined by the rated output power as well as the voltage and current rating.When the power supply is configured so that the total output (current x voltage output) is less than the rated power output, the power supply functions as a typical constant current, constant voltage power supply.If however, the power supply is configured such that the total output (current x voltage output) exceeds the rated power output, the effective output is actually limited to the power limit of the unit. In this case the output current and voltage then depend purely on the load value.Below is a comparison of the operating areas of each power supply.72-1335072-13360Note: the specifications below are tested under the conditions of temperature 25°C ±5°C and the warm-up for 5 minutesTM/exclusive-brands /exclusive-brands Models 72-1335072-13360POWER Voltage Current300W 0-30V 0-30A 300W 0-60V 0-15A Load RegulationVoltage Current≤0.01% +3mV ≤0.1% +5mA ≤0.01% +2mV ≤0.1% +5mA Line RegulationVoltage Current≤0.01% +3mV ≤0.1% +3mA≤0.01% +3mV ≤0.1% +3mASetup ResolutionVoltage 1mV 1mV Current1mA 1mA Read Back ResolutionVoltage 1mV 1mV Current1mA 1mA Setup Accuracy (25°C ±5°C)Voltage ≤0.5% +3mV ≤0.5% +5mV Current≤0.5% +5mA ≤0.5% +3mA Voltage Rise TimeRise Time ≤50ms ≤65ms Fall Time≤50ms ≤50ms Ripple (20-20M)Voltage ≤1mVrms ≤2mVrms Current≤3mArms ≤3mArms Temp.
