PS9DC01 6-30V Battery discharge protection module Product Specifications: Operating voltage: DC 6-30V. Operating current (12V): Standard mode, standby current 7MA; Working current 11MA; Energy-Saving mode,Standby current 4MA; Working current 7MA. 3 control buttons, 4 bit digital display, 1 LED charge indicator. Mode: Standard-Mode, Energy-Saving Mode, Setup-Mode, Voltage-Calibration, Factory-Settings. Can protect any 6-30V battery discharge, double N-MOS maximum load current: 15A (6-15V); 10A (15-30V) .The default Cutoff discharge voltage 11.8V, Start discharge voltage is 12.2V(for 12V lead acid battery). Size : 60 x 35x 16mm Weight : 19g Features: 1 Photoelectric isolation can effectively protect the circuit board. 2 1% high-precision divider resistors make the measurement voltage more accurate. 3 Voltage accuracy and resolution is 0.1V, and with a calibration function. 4 Reduce the brightness of the digital display, save energy and protect your eyes. 5 parameter power-down save, to avoid duplicate settings. 6 Set the Start Discharge Voltage(H) and Cutoff Discharge Voltage(L) to the lowest (power on). For example, the power supply voltage is 12.00V and the module display voltage is 12.34V. At this time, calibration is required. 1.Press and hold the SET button first, and then power on (be sure to press the button first, and then power on), then the digital tube displays 12.34V;2.Trigger DEC or INC button, let the digital tube display 12.00V 3.Trigger the SET button again to save the parameters. (If you do not want to save the parameters, please power off) Factory-Settings:In the Standard-Mode, press and hold the SET and INC buttons at the same time, until the digital display shows8888, at this time, restore the factory settings, Cutoff-Discharge-Voltage is 11.8V, Start-Discharge-Voltage is 12.8V. (Note: voltage calibration parameters cannot be reset to factory settings) Operation Steps (must follow the steps): Example 1: We want to set 12V lead-acid battery discharge protection function, Cutoff-Discharge-Voltage is 11.7V and Start-Discharge-Voltage is 12.9V. Step 1: Connect the batterys positive and negative ports to the modules BAT+/BAT- ports (to ensure that the battery has more than 20% of the capacity); the digital tube will display the battery voltage (such as the battery voltage is 12.1V, the digital display will show C12 .1) Step 2: Trigger the INC button, the digital display will show H12.8, then trigger the SET button, H will flash, this is the Start-Discharge-Voltage setting mode.Step 3: In the Start-Discharge-Voltage setting mode, trigger the INC button to increase the voltage and the DEC button to decrease the voltage. Long press INC or DEC button to quickly set the voltage.Step 4: Set the voltage to H12.9 and trigger the SET button to save the settings.Step 5: Trigger the DEC button, the digital display will show L11.8, then trigger the SET button, L will flash, this is the Cutoff-Discharge-Voltage setting mode.Step 6: In the Cutoff-Discharge-Voltage setting mode, trigger the INC button to increase the voltage and the DEC button to decrease the voltage. Long press INC or DEC button to quickly set the voltage.Step 7: Set the voltage to L11.7 and trigger the SET button to save the settings.Step 8: Disconnect the port BAT +/BAT- and connect the port OUT+/OUT- to the load.Step 9: Connect the port BAT +/BAT- again and re-power it. After 3 seconds delay, the load will be powered.Example 2: Start-Discharge-Voltage(H) and Cutoff-Discharge-Voltage(L) has been set, Direct wiring.Step 1: Connect port OUT+/OUT- to the loadStep 2: Connect the batterys positive and negative ports to the modules BAT+/BAT- ports (to ensure that the battery has more than 20% of the capacity); the digital tube will display the battery voltage (such as the battery voltage is 12.1V, the digital display will show C12 .1)Step 3: Power is supplied to the load after a delay of 3 secondsQ&A:Q1: The suitable battery voltage? Types of Batteries?A1: This module is suitable for all batteries in the range of 6-30V, lead-acid batteries, lithium batteries and even dry batteries. Battery type : Lead-acid /Ni-Cd / Ni-MH / Li-ION /Li-PO / LiFe /Polymer Lithium battery.Q2: Can parameters be saved after power off?A2: Yes, the parameters can be saved when powered off.Q3: Why does the digital tube not display after the battery is connected?A3: 1. It may be that the battery capacity is too low. Please charge the battery with the charger first. 2. Poor connection or reverse polarity 3. It is possible that the module has entered the Energy-Saving Mode,press and hold the SET button until the digital display.Q4: Why cant I increase the Cutoff-Discharge-Voltage(L)?A4: Please increase the Start-Discharge-Voltage(H) first.Q5: Why cant I discrease the Start-Discharge-Voltage(H) ?A5: Please discrease the Cutoff-Discharge-Voltage(L) first.Q6: Why relay turn on and off frequently?A6: 1 It may be too much load current, or the battery capacity is too small. 2 It may be Cutoff-Discharge-Voltage(L) and Start-Discharge-Voltage(H) too close.Q7: What is the control method? Can it be used as a charge protection? Can it limit the current?A7: 1 This is a voltage control method 2 NO! This can only be used for discharge protection. It cannot be used for charging protection. For charging protection, please use the PS46A01 module. 4 No! This module can only control the voltage and cannot control th
