Small size DC contactor relay comes with 20A rated current, sectional 12V/ 24V DC coil voltage, one set normally open (SPST-NO), max. switching voltage 450V DC. The main contactor is equipped with a sealed structure, can work stably with the protection of inert gas. High performance DC contactor is widely used for new energy vehicles pre-charge.
Features and Benefits
- 20A contact switching capability, max. switching voltage 450V DC.
- The high voltage DC contactor has a set of normally open bridge contacts and the contact loop is non-polar.
- Ceramic brazing technology is adopted, contacts will not be oxidized and can be quickly cut off at DC high voltage.
- Compact size and light weight, sealed structure for main contact, suitable well for working continuously in harsh environment.
- Flexible installation and 12V/ 24V/ 48V/ 60V various coil voltages are available to meet the various needs.
- Low coil power consumption 3.5W with the DC contactor to effectively reduce the control loss. It is especially suitable to be used in battery-powered occasions to prolong the battery life.
- Application: Energy storage system, electric vehicle, photovoltaic inverter, telecommunication equipment, AGV system, solar energy system, construction machinery, battery car, charging pile, train, ship, winch, uninterruptible power control system.
