Panel Function Description
- Power Switch: Used to turn the power supply on or off.
- Voltage Regulation Knob (VOLTAGE): Used to adjust the voltage setting. Turning clockwise increases the value, counter-clockwise decreases it. Pressing the encoder switch shifts the digit to the left. After 3 seconds of completing the voltage setting operation, the blinking stops and the current setting value is saved.
- Current Regulation Knob: Used to set the current. Turning clockwise increases the value, counter-clockwise decreases it. Pressing the encoder switch shifts the digit to the left. After 3 seconds of completing the current setting operation, the blinking stops and the current setting value is saved. WPS models also feature: long press to enable/disable short-circuit protection.
- Output Switch: Used to turn the power supply output on or off. When a short-circuit protection alarm occurs, pressing this button releases the alarm and returns to the output-off state.
- Voltage Display: Displays the set voltage value or the actual output value. When setting voltage, it shows the set voltage. When output voltage is enabled, it shows the actual output voltage.
- Current Display: Displays the set current value or the actual output value. When setting current, it shows the set current. When output current is enabled, it shows the actual output current.
- Power Display: Displays the output power.
- Constant Voltage (CV) Indicator: The CV indicator lights up when the machine operates in constant voltage mode.
- Constant Current (CC) Indicator: The CC indicator lights up when the machine operates in constant current mode.
- OCP Short Circuit Indicator: Indicates whether the OCP function is enabled. It lights up when OCP is enabled.
- Output Indicator: A lit indicator signals that the power supply output is on, and an unlit indicator signals that the power supply output is off.
- Positive Output Terminal (+): Used to connect the positive pole of the load device.
- Negative Output Terminal (-): Used to connect the negative pole of the load device.
- Grounding Screw: Used for grounding.
- Independent USB Fast Charging Interface: This device supports USB fast charging, with a built-in fast charging protocol chip and an output power of up to 18W. It can provide fast charging for mobile phones, PADs, power banks, and other devices with fast charging capabilities. It automatically adjusts the output voltage and current according to the charging device's fast charging protocol. For electronic devices without fast charging, it will charge at the standard 5V.
- Cooling Fan: Used for heat dissipation from the chassis. It is temperature-controlled, activating when the temperature reaches the required dissipation level.
- AC Input Socket: AC power input socket.
- Fuse Box: Used to store the fuse for easy replacement.
- USB Host Computer Interface (Optional): Used to connect to a computer for remote control of the power supply. The host computer software can be downloaded from the official website. Download link: wanptek.com
- AC Input Voltage Selector Switch: This machine supports dual voltage operation (AC115V or AC230V), which must be selected using this switch.
- OCP Short Circuit Protection Switch (APS models only): For APS models: Pressing the OCP button enables/disables the OCP short-circuit protection function. When this function is activated, the indicator lights up. If a short circuit occurs in the load, the machine stops output and alarms. Pressing the Output button releases the alarm and returns to the output-off state. For WPS models: Long-pressing the current knob enables/disables the OCP short-circuit protection function. When this function is enabled, the indicator lights up. If a short circuit occurs in the load, the machine stops output and alarms. Pressing the output button releases the alarm and returns to the output-off state.
- Storage Button (M1-M3, APS models only): APS models have 3 sets of memory functions for easy storage and recall of commonly used parameters. Long-pressing any M1-M3 button saves the currently set voltage and current values. Short-pressing any M1-M3 button recalls the previously stored voltage and current values. WPS models do not have this function.
Requirements
- Use a power cord that meets the power requirements of this product.
- Before use, the power supply must be reliably grounded. The weak leakage current caused by the internal anti-electromagnetic interference circuit of the power supply must be grounded; otherwise,
