WDPS3205 5A DC-DC Adjustable Step Down Power Supply Module Buck Converter CNC Power Supply

WDPS3205 5A DC-DC Adjustable Step Down Power Supply Module Buck Converter CNC Power Supply

Attention:
Please read introductions carefully before use. The module has passed tests before delivery. After receiving the goods, please browse its wiring method first, and then power on.

Version Description:
- WDPS3205: Without function for MODBUS.
- WDPS3205M: For MODBUS version. The power supply for MODBUS version has an RS485 communication interface, which can be set or collected by a host computer software, and it can also communicate with PLC, DCS, smart meters and other devices!
- Other functions of the two versions are the same!

PS: If you buy the version for MODBUS, it is recommended to use our USB to 485 module to avoid compatibility issues with other brands of serial port modules causing it to fail to communicate normally and waste your time. If the USB to 485 module is needed, please contact us to pay extra money. Thank you!

Features:
- DC adjustable digital control step-down power supply module.
- Coded numerical control is more convenient.
- LCD screen with voltage and current dual display.
- Constant voltage and current.

Product Parameters:
- Input voltage: 6V-36V
- Output voltage: 0-32V continuously adjustable (can only be used as a step-down module, the input voltage must be greater than the output voltage by more than 1V)
- Output current: 0.01A-5A continuously adjustable (please strengthen heat dissipation when the temperature exceeds 60℃. There are reserved fan installation positions and wiring terminals. If necessary, you can purchase the version with a fan)
- Output power: maximum 160W (recommended to use within 120W, please reduce the power when using large pressure difference)
- Working temperature: -10 to 75℃(pay attention to the temperature of the power tube when using it, please strengthen heat dissipation when it exceeds a certain temperature. There are reserved fan installation positions and wiring terminals)
- Resolution accuracy: voltage 0.01V, current 0.01A, 1%±1 digit
- Conversion efficiency: up to 95%
- Short-circuit protection: Yes, the constant current value currently set

- Opening size: 76 x 39mm (LxW)
- Weight: 75g

Package Included:
- 1 x Set of Power Supply Module

Note:
- Items with RS485 serial port is only for MODBUS version. Goods in other versions comes without RS485 port.

Setting Instructions:
Output Voltage Setting:
Short press CV key to enter voltage setting mode, turn the potentiometer to adjust the current voltage value, press the potentiometer to switch between coarse adjustment and fine adjustment. After adjustment, short press CV key to save and exit.


Output Current Setting:
Short press CC key to enter current setting mode. Rotate the potentiometer to adjust the current current value, press the potentiometer to switch between coarse and fine adjustment. After adjustment, short press CC key to save and exit. (Please note that indicator light will change to red when the current is constant, and the constant current can be adjusted. Only when the actual load output current is greater than the set current, it is in constant current mode and constant current is adjustable. Otherwise it will work in a constant voltage state. When the current is adjusted to 2A, it does not mean that any connected equipment will become 2A.)


Display Mode Setting:
Short press MODE to switch the display mode. IN is the display input voltage, and OUT is the display output voltage.


Output ON/OFF Setting:
Short press the potentiometer button directly to turn on or off output voltage. When it is off, the current position displays OFF.
