Publication time : 2018-6-14 14:08:41 
DC power supply
It provides the stable DC voltage and DC current, has the function to keep constant voltage, current and power, adopts the IGBT as main control element and is characterized by small volume, high efficiency, high precision and fast dynamic response.

  The monitoring and communication chip adopts ARM32 bit processor, which can be applied to various intelligent control schemes.

  The IGBT is the main control element, and the medium and high frequency transformers are isolated.

  Automatic switching of constant voltage, constant current and constant power.

  The dynamic response and the speed of stability are fast.

  High precision and small output ripple.

  The external battery pack is equipped with charge and discharge management function.

  The protection function is complete, overload, overpressure, overcurrent, over temperature, under voltage, short circuit and so on.

  LCD parameter display, setting value and actual value are displayed at the same time.

  RS232 communication interface, standard MODBUS-RTU protocol, can be transferred to any other protocol.
