HZT-RGU, a complete set of IGBT synchronous infeed/regenerative feedback products, mainly consists of three-phase incoming circuit breaker, incoming reactor, SINAMICS S120 installed cabinet type unregulated power module (SLM), forming a 6-pulse or 12-pulse DC power supply circuit.

In today's rapid development of papermaking, metallurgy, coal mining and other industrial industries, the infeed unit provides a stable DC power supply for the drive system of the workshop, which is a key link to ensure the safe production of enterprises.

The products are divided into 400VAC and 690VAC according to the input power supply voltage level, and are divided into 250 ~800kW (400V, single unit), 450 ~1400kW (690V, single unit) according to the power distribution capacity, and can be used in parallel to increase the distribution capacity.

The IGBT Synchronous Infeed/Regenerative Feedback Package uses the Siemens SINAMICS S120 unregulated power supply module (SLM) to provide the infeed/regenerative feedback unit of the power supply. The  infeed is carried out through the IGBT's anti-parallel diode bridge, and    the stable and grid-controlled regenerative feedback is carried out through the IGBT at 100% continuous feedback power. The regenerative feedback capability of the module can be disabled by parameter setting. The DC bus is precharged by an integrated precharge resistor.
