1 Working power supply: dual power supply (two power supplies can not be powered at the same time): Power Supply 1 DC 7-25V; Power Supply 2 DC 5V (Power Supply 1 voltage has been calibrated, if you want to use Power Supply 2, please calibrate the voltage again

2 Working current (DC 12V) Standby Current (all relays are off) 16MA, 1 relay "open" 50MA, 2 relays "open" 82MA, 3 relays "open" 115MA, 4 relays "open" 150MA

3 Measurement voltage: DC 0-25V; 1 0-25V analog control relay, 2 protection 1-25V battery charge, 3 protection 1-25V battery discharge, 4 4 channel 0-25V voltmeter. The battery refers to a lead-acid battery, a lithium battery, etc. that can be charged.

4 4-channel analog measurement and control, each channel's parameters are set independently, power-down save, measurement accuracy 0.1V.

5 Size: 80*66*18mm

6 Weight: about 76 grams

Note:

1 There are two power supply interfaces. Please do not use two power supplies at the same time. It is recommended to use only one power supply interfaces.

2 The maximum voltage that the analog input interface(IN1/IN2/IN3/IN4) can withstand is 30V. Please do not use it under overvoltage.

3 If the measured voltage is not accurate, please follow the “PS23A04 Voltage calibration” manual and the video calibration voltage.
