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 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 to use our PC software to control the power supply. The communication protocol is divided into a simple communication protocol and a communication protocol,which can be freely 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,Quick discharge function,voltage adjustment response speed is 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.
