OPERATION INSTRUCTION
There are two types of power output modes: constant voltage (CV) and constant current output (CC). The output mode is determined by the voltage and current values set by the user and the load connected by the user. The output voltage or current value of the power supply won't exceed the voltage and current values set by the user. In constant voltage mode, the output voltage value is equal to the user-set voltage value. In constant current mode, the output current value is equal to the user-set current value.
For example: the voltage value is set to 5V and the current value is set to 5A.
Steps
- Turn on the power switch
- Adjust the voltage adjustment knob to 5V
- Connect the "positive" and "negative" with wires and adjust the current knob to 5A.
- Disconnect the wire and connect the load to use.
CONNECT THE LOAD
1. Rotate the terminal knob by turning it counterclockwise
2. Insert the load terminal
3. Turn the terminal knob clockwise
4. Banana plug can be directly inserted into the terminal hole
Diagram shows a banana plug being inserted into a terminal. The terminal knob is shown being turned counterclockwise to open, then clockwise to secure.
❗ Improper connection may result in damage to the power supply and the load connected to the power supply. When connecting the battery load, do not reverse the polarity of the "+" and "-" as this may damage the power supply.
CONSTANT VOLTAGE / CONSTANT CURRENT CHARACTERISTICS
The working characteristics of this series of power supplies are constant voltage/constant current automatic conversion type, which can automatically change between constant voltage and constant current states with load changes. The intersection between constant voltage and constant current mode is called conversion point. For example, if the load causes the power supply to operate in a constant voltage mode, a constant voltage is output. As the load increases, the output voltage will remain constant and the output current will increase. When the current value reaches the set current limit value, the power supply will automatically switch to constant current mode. The output current remains stable and the output voltage decreases proportionally as the load increases further. The conversion of constant voltage and constant current is indicated by the LED on the front panel.
CV indicator light is on during constant voltage, CC indicator is on when constant current.
❗ Incorrect AC voltage input will cause serious damage to the device. Please make sure the required input voltage value.
FUSE REPLACEMENT
If the fuse blows, the power supply will stop working. To find and correct the cause of the blown fuse, then replace it with a fuse of the same specification.
Diagram shows two steps for fuse replacement. Step 1: Remove the power plug, then open the fuse cabin according to the illustration. Step 2: Replace the fuse of the same specification, then put the fuse cabin back. The fuse cabin is shown in the power socket.
⚡ HIGH VOLTAGE! ❗ DANGER! For effective safety protection, it is only necessary to replace the fuse of a specific specification. Before replacing the fuse, the power must be turned off and the power cord must be unplugged from the power outlet.
MAINTENANCE
Disconnect the power when the product is not in use.
Unplug the power supply before cleaning.
Do not use hydrocarbons, chlorides or similar solvents, or use abrasive cleaners.
