http://68.168.132.244/DPH8900/material.html

►Based on the switching power supply technology of BUCK structure, the working frequency is up to 150KHz, and with the minimum differential voltage of 0.5V can still work stably;

►Input DC voltage 20-110V, with a AC (AC to DC) switching power supply or battery, you can combine them into a high-precision digital adjustable DC power supply or charger;

►The output voltage is 0-96V digitally continuously adjustable, the minimum voltage resolution is 10mV, and the rple is lower than 50mVpp;

►The output current is divided into 0-20A (minimum resolution 10mA), The current is digital and continuously adjustable;

►Provide PC software and communication protocol to support secry programming control;

►Standard "USB to TTL" supports TTL serial communication,It is convenient for everyone to use our PC software to control the power supply;

►The communication protocol is divided into a simple communication protocol and a MODBUS-RTU communication protocol, which can be freely selected in the machine menu;

►It can set the power-on automatic output, with its own temperature-controlled fan, intelligently adjust the speed, and it can automatically stop output when over-temperature;

►With quick discharge function, the voltage response speed is adjusted very fast;

►Automatically save parameters when power is off, there are 10 groups of M0~M9 storage locations, which can be saved and recalled at any time;

►The internal structure is simple, and it is divided into two parts: the main board and the display board. Removing the shell allows for easy integration into your own device.
