Three electrodes - controlled power supply device

This is an electrochemical device, a total of three conductive leads, respectively, 1,2,3 wires. The device has three working modes: Three electrodes - constant voltage mode 1. The total power supply of the device is the DC adjustable power supply that provides external DC power. Wires 1 and 2 are external output terminals. 2. Use the DC adjustable power supply to output the constant voltage after the voltage change. 3. The device needs to input a voltage value, and the built-in precision voltmeter tests the output voltage value. The device compares the output voltage value and the input voltage value. If the allowable error range is exceeded, the DC adjustable power supply is adjusted to change the voltage value of the output wire, so that the voltage value of the output wire is consistent with the set. 4. If the voltage value of the output wire is adjusted to 0 or the maximum (18V), and the voltage value of the output wire still cannot meet the set value, the power supply will work at 0 or the maximum (18V). 5. Monitoring and regulation are continuous, and are always implemented during the power supply operation. Two electrodes - constant voltage mode 1. Precision voltmeter is disabled 2. The device input a voltage value, adjust the DC adjustable power supply, change the voltage value of wire 1 and wire 2, so that the voltage value of wire 1 and wire 2 is consistent with the set. The set value is limited to 0-18 V Two electrodes - constant current mode 1. The device input a current value, adjust the DC adjustable power supply, so that the actual current value of wire 1 and wire 2 is consistent with the set. 2. Precision voltmeter is not disabled, and the device displays the value of the precision voltmeter when working.
