As the vehicle battery capacity increases, the rated voltage increases and the external charging expands. Therefore, it is necessary to monitor the increase of DC relay voltage and the opening/closing of contact points.
The HC-F series is rated at DC 800-1500 V, 4010 A ~ 400 A. The HCF400 can be used to check contact opening/closing by monitoring the auxiliary contacts. These products are UL, IEC,CUL,TUV,CE and CCCcertified.
The HCF400 is rated at 1500 VDC, 400 A with one auxiliary contact. Both are UL and IEC approved. In addition, an advantage is that this series can be used for systems with bidirectional blocking, such as reverse blocking or charging/discharging of the system, by applying a bidirectional magnet interrupter structure.
As the global trend of renewable energy continues to expand, the demand for Hecheng HVDC relays is expected to grow exponentially. Fast chargers for electric vehicles convert AC to DC to supply power to the vehicle, while high-voltage DC relays are used to supply and disconnect power. eSS is a system that stores power and uses HVDC relays between the battery and PCS. HVDC relays are used to turn on/off solar modules in photovoltaic systems.
Based on its achievements in DC 400V electric vehicles, Hecheng will continue to commercialize HVDC relays to DC 1000V and DC 1500V for electric vehicles and chargers, and will continue to be a pioneer in the renewable energy market.
