It mainly charges the batteries on EMUs and supplies power to DC loads at the same time. Phase-shifted full-bridge soft-switching technology is adopted with high efficiency and good reliability. Mainly used in CRH1, CRH3 series EMUs
It mainly provides 220V single-phase AC power supply for the interior lighting system, socket and other equipment of EMU. It adopts high frequency isolation mode, and has the characteristics of small size, light weight and high reliability.
Water pump system inverter power supply
The AC 100V/50Hz control power supply is used in the bathroom pump system of EMU.Mainly used in CRH2, CRH6 series EMUs.
Emergency ventilation inverter
The standby power supply of air conditioning unit provides power for train compartment ventilator in case of failure, which ensures smooth ventilation, small size, light weight and high reliability in train compartment. Mainly used in CRH6 series EMUs.
Power conversion device for rescue
This equipment is an emergency power supply equipment used in the rescue of locomotives when a major train failure occurs. It converts the DC110V power supply of locomotives into DC100V power supply. It mainly provides emergency power supply for the necessary control, braking, lighting and living equipment of EMUs.Mainly used in CRH6 series EMUs.
Axis temperature detector
The product is a temperature sensor, which is used to detect the temperature of axle end and gear box of EMU. When the temperature exceeds the limit set by the detector, the axle temperature detector is open. Mainly used in CRH2, CRH6 series EMUs.
Vehicle-outside temperature acquisition system
The product is used to collect the temperature outside the vehicle, which is divided into two parts: the external temperature sensor and the interface box of the external temperature sensor.Mainly used in CRH2, CRH6 series EMUs.
Under-vehicle holding temperature relay
The product is used to detect the ambient temperature of the water tank of EMU, and to detect the ambient temperature of the water tank through its temperature sensor, so as to protect the water tank of the train from the influence of low temperature.Mainly used in CRH2, CRH6 series EMUs.
Auxiliary brake mode generator
This product is composed of SBT and ASBT. When the main brake device of EMU is not good or the EMU breaks down and rescues, it provides emergency power for EP valve in the auxiliary brake controller of each EMU head.Mainly used in CRH2, CRH6 series EMUs.
