High Voltage DC Relays
DC relay is a kind of switchgear used to control the current in the direct current circuit, which is widely used in many fields. Its main uses include the switch and protection of battery charging and discharging lines in new energy vehicles, and the safety mechanism to prevent equipment failure, short circuit and fire.
- DC relay permanent magnet arc blowing
- High voltage DC disconnection
- Polarity requirements at contact end
- No polarity requirements at coil connection end
Power Relays
Designed for heavy-duty applications, our power relays deliver exceptional endurance. They are widely used in industrial automation, power systems and rail transit, such as controlling the switch of HVDC transmission lines, the operation of large mechanical equipment, and the start, braking and speed regulation of trains.
- High load switching capacity
- Low power consumption
- Excellent thermal resistance
Latching & Automotive Relays
Our Latching Relays and Automotive Relays offer energy-efficient state retention and robust vibration resistance. SuChen relays can be customized according to customer requirements, such as installation position, etc., ensuring seamless integration into your specific PCB or panel layouts.
- Customizable installation positions

Core Technological Innovations & Applications
Driving the future of new energy and industrial control with cutting-edge engineering.
Improve the arc extinguishing ability
The permanent magnet blowing arc extinguishing technology generates a strong magnetic field near the arc, so that the arc is wound into a spiral shape, increasing its length and resistance, thereby accelerating the dissipation of energy and achieving the purpose of quickly extinguishing the arc. This technology can significantly improve the arc extinguishing performance of the relay and the service life of the contact.
Adapt to high voltage environment
The high voltage DC relay needs to cut off the circuit at high voltage, and the permanent magnet blowing arc technology can quickly cut off the high voltage DC load, avoid the occurrence of abnormal conditions such as contact adhesion or relay explosion, and ensure driving safety. This technology is especially suitable for high voltage applications such as new energy vehicles and charging piles.
