ZZG12 Series HF switch type rectifier is researched and produced basing on the rich experiences of operational power supply by our company. It adopts the soft switch change technique to explore switch type rectifier especially used for power operation power supply.  One or more equipment can be combined to supply power to D.C. loaded, and charge the battery, which can meet the operation requirement of rectifier. It can be widely used in power plant, substation and also generally used to stabilized the D.C. Voltage and Current of power supply.

ZZG13 series high frequency switching rectifier module is manufactured by our company on the basis of many years experience in the field of developing and manufacturing power supplies, which is specially used for the dc operating power supply in electric power system. The module can be used in a single module way or in way of many paralleled modules to supply dc load and meanwhile to charge the batteries. The module can be widely used in power plants and substations and also it can be used as the dc voltage constant or current constant power sources.

ZZG22 series high-frequency switching rectifier is switching type model specially developed for power operating power system using many years experience of producing power operating power system, adopted the soft switching transferring technology ,which can supply power to DC load with signal or many running models in parallel, at the same time supplying power to storage battery , satisfying the rectifier requirement of power operation power system,Which can be used in power plant, substation widely , also used as the usual DC stable voltage, stable current power.

ZZG23 series high-frequency switching rectifier is switching type model specially developed for power operating power system using many years experience of producing power operating power system, adopted the soft switching transferring technology, which can supply power to DC load with signal or many models parallel running ,at the same time supplying power to storage battery , satisfying the rectifier requirement of power operation power system . Which can be used in power plant, substation widely, also used as the usual DC stable voltage, stable current power.
