DKP3603 Adjustable High Precision DC-DC Constant Voltage and Constant Current Step-down LED Driver Power Supply

Instrument Introduction

The DKP3603 DC-DC CNC step-down module is a fully digital display programmable step-down module with small size, high power, high efficiency, and stable operation. It adopts advanced microprocessor control, and the voltage and current are precisely adjusted by buttons. It can output constant voltage and current, and can communicate with microcontrollers or computers through reserved ports for easy secondary development. Equipped with four digit eight segment LED Nixie tube, which can display the output voltage and current in real time. At the same time, this CNC voltage reduction module is equipped with a working status indicator light, which can view the working status in real-time. After powering on, this machine has an automatic output function that can be turned on or off as needed. In addition, this machine also has a button locking function that can lock parameter adjustment buttons to prevent misadjustment of output voltage and current parameters.
