Operation instructions:
There are two modes of power output : constant voltage output ( C V ) and constant current output ( C C ) . The output mode is determined by the voltage and current values set by the user and the load that the user receives . The output voltage or current value of the power supply will not exceed the voltage and current value set by the user. In the constant voltage mode , the output voltage is equal to the voltage set by the user. In constant current mode, the output current value is equal to the current value set by the user.
Voltage Regulation
- 1. Adjust the voltage roughly to the required voltage value , the fine-tune the knob to the required specific voltage value
- 2. In general , the current knob can be adjusted to the maximum , and then the load can be connected for use
Current regulation
When the user needs to adjust the limiting current output
- 1. firstly , adjust the voltage to about 5-10V , then short-circuit the positive and negative terminals with wires ( short-circuit alarm needs to be set to C C position )
- 2. Adjust the current to roughly adjust the knob to the required current value , and then fine-tune the knob to the required specific current value
- 3. After disconnecting the short-circuit conductor and adjusting the required voltage by voltage regulation " method , the connection load can be used
