product details

Product Applications

HVDC transmission: In HVDC transmission systems, HVDC relays are used to control converter valves, circuit breakers and other equipment.

New energy power generation: In the field of new energy such as solar power generation and wind power generation, HVDC relays are used to control inverters and energy storage systems.

Special equipment: In some special equipment that requires high voltage control, high voltage DC relays are also used.

High voltage DC relay features

Coil resistance is large: because the control voltage is very high, the coil turns are very many, the resistance is very large, so the working current is very small.

Large contact capacity: HVDC relays can control very high-power loads, and the contact capacity is generally more than 50A.

Large volume: HVDC relays are very large and require special installation space and heat dissipation measures.

Expensive: The production process of HVDC relays is very complex and the price is very expensive.

Selection of HVDC relay

Control voltage: Select a relay that matches the voltage of the control circuit.

Coil resistance: Select the appropriate coil resistance according to the drive capability of the control circuit.

Contact capacity: Select the appropriate contact capacity according to the current and voltage of the load.

Installation mode: Select the appropriate relay installation mode according to the installation space, such as cabinet installation and bracket installation.
