DPH8909/20 series programmable DC power supply module can digitally display the output voltage、 current、temperature and other parameters. They have two different output status of constant voltage and constant current. They are especially suitable for use in factory equipment power supply, product aging and debugging, solar charging, LED lamp bead driving and battery charging and discharging.
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 10-75V, with a AC-DC (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 0-60V digitally continuously adjustable, the minimum voltage resolution is 10mV, and the ripple is lower than 50mVpp;
The output current is divided into 0-5A (minimum resolution 1mA), The current is digital and continuously adjustable;
Provide PC software and communication protocol to support secondary 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.
Power supplies can be used in the following fields:
Power field, mainly used for integrators and meters, smart meters, LED drive;
Industrial control field;
Medical equipment, mainly including tire guards, monitors, etc;
Military industry, military equipments;
Solar voltage regulation, battery charging and discharging, etc
