Zhongheng Power Module ZHR22010-3 DC Panel Charging Module Rectifier Module

Module model: ZHR22010-3

Main features of the module:

The whole process of soft switching technology, high efficiency, low power consumption, small size.

Ac input with built-in safety tube.

Measures to implement hot swap. For other products of the same type without built-in diodes, users need to add additional diode heat sink on the DC screen, and the wiring is complicated.

Adopt the "three-phase passive power factor correction circuit", input no center line, power factor up to 0.94.

Independent flow sharing is adopted, and the non-uniform mobility of parallel machine is <±3%, which can ensure the good parallel of more than 20 modules.

Module with RS-485 interface, convenient access to automation system for communication. ** Output overvoltage protection: built-in overvoltage protection circuit, the module automatically locks after overvoltage, the module fault indicator is on, the fault module automatically exits the work, does not affect the whole system 160V±5% ** output current limiting protection: the maximum output current of each module is 1.05 times of the rated output current.

Short-circuit protection: The retraction sag current limiting mode is adopted. When the output short-circuit is short, the module will pull the output voltage down to zero instantly and limit the short-circuit current below 15% of the rated output current. The module can work in the short-circuit state for a long time without damage. After the fault is removed, the module can automatically resume work.

Shunt protection of modules: there is a shunt protection circuit inside the module. When the fault occurs, the module automatically exits from the system and does not affect the normal operation of other modules. (** Overtemperature protection: The module automatically shuts down when the temperature of the radiator exceeds 85℃, and automatically starts when the temperature drops
