[Introduction of Solution]

After being switched in the Y shape, one of the two paths of AC input is outputted. The AC part is outputted after the isolation of the AC voltage stabilizing modules connected in parallel and the transformer, and the DC part is outputted by the DC voltage stabilizing module.

The work of parallel connection of the AC module is realized by the digital control technique. It completely solves the problems that in module switching, the output is interrupted caused by the hot standby system or in module switching, the backup module fails, etc. All modules work with load, the module failure is knowable, and there is zero interruption in module switching. It greatly increases the reliability and availability of the signal power supply system.

  To the intelligent monitoring, because of its independent design ability, Dinghan can realize the centralized monitoring of the county level and the centralized monitoring of the city level so as to provide various choices for the customer.
