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
