4.2. Esquema de cablejat
Refer to the diagram below for proper input and output connections, as well as optional serial communication and external temperature probe interfaces.
Image: Detailed Wiring Diagram of the DC Buck Power Supply, showing IN+, IN-, OUT+, OUT-, Serial Communication Interface (GND, RX, TX, 5V), and NTC temperature probe interface.
4.3. Bare Board Configuration (if applicable)
If you purchased a bare board, switches, potentiometers, and dial switches will be pre-welded. If a set with a screen meter is purchased, these are not welded by default.
Image: XY6530 Bare Board with DIP Switches for configuration.
The bare board supports MPPT and analog 0.3-10V control, with serial communication + on-board 485 communication (both can be used simultaneously). The output voltage és ajustable de 0-65V i el corrent de sortida és ajustable de 0-50A.
Image: Bare Board with Analog Control and DIP Switches for current adjustment.
To enter potentiometer mode, flip the switch up to light the green indicator light. Conversely, it operates in the digital control meter mode. In potentiometer mode, the output voltage (vol constanttage) can only be controlled through the potentiometer; the constant current value can be set via a DIP switch, with a total of 16 gears to meet most scenarios (can also be set via Modbus).
4.4. Battery Charging Setup (MPPT)
The unit supports MPPT solar charging and features automatic stop when fully charged, and automatic charging at low battery. An external temperature probe can be connected for over-temperature protection. Attach the external temperature probe to the battery; charging will stop automatically if over-temperature is detected.
Image: MPPT Solar Charging Diagram showing connections for solar panel, battery, and NTC temperature probe.
Precaution: Ensure the unit is OFF before connecting the battery. Avoid reverse polarity connection to prevent device damage or fire hazards. Turn on the output ONLY after the battery icon appears on the screen to initiate charging.

Use an infrared remote control or 433M wireless remote control module to set voltage and current directly with the remote's numeric keypad.
5.3. CV CC CW Features
The power supply operates in Constant Voltage (CV), Constant Current (CC), or Constant Power (CW) modes depending on the load and settings.
Image: Display showing CV, CC, and CW modes with their respective values.
- CV/CC Mode: When the constant power function is not turned on, the power supply only has CV and CC functions, which automatically switch based on the load. If the load current is less than the set constant current value, the power supply is in CV mode, where the output voltage is the set CV value, and the current is adaptive.
- Mode CW: Després d'activar la funció de potència constant, el valor de corrent constant es posa per defecte al valor màxim i el vol constanttage value (CV) serves as the initial voltage. El vol corresponenttage can be calculated based on the set constant power value using the power formula P=U/R. The constant power point algorithm automatically follows.
Constant Power Switch and Constant Power Value Setting:
- In the system parameter settings UI, select the CW option. Turn ON to enable constant power, and turn OFF to disable constant power.
- Després d'habilitar la potència constant, premeu ISET breument a la interfície principal per modificar el valor de la potència constant.
