Based on the switching power supply technology of structure, the working frequency is up to 150KHz, and with the minimum differential voltage of 0.5V can still work stably; Input 10-75V, with a AC-DC (AC to DC) switching power supply or battery, you can combine 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 0-24A (minimum resolution 10mA), The current is digital and continuously adjustable; 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 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 in the machine ; It can set the power-on automatic output, with 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 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.
