EVQ300
300A electromagnetic DC contactor, DC 12-900V, contactor coil voltage 12V/24V, 48V/72V
High voltage DC contactor, normally open (SPST-NO), 300 amps rated load current, available with 12V/24V, 47/72V coils.
It’s widely used as EV contactor, main contactor in charging station, EV, HEV, photovoltaic, energy storage, AGV, UPS, etc.
- Epoxy sealed.
- Magnetic arc blowout.
- Compact design, low noise.
- Build-in energy saving board
- Bi-directional, optional with polarized or non-polarized contact.
- Optional auxiliary contact.
- CE, CCC and RoHS compliant.
EVQ Series Contactors can switch DC loads at both low and high voltage from 12 to 900VDC. These hermetically sealed contactors can be mounted in any position, can be used in nearly any harsh environment at temperatures from –40°C to 85°C. They are the preferred contactor (sometimes called a relay ) for electric vehicles, hybrid vehicles,heavy trucks and equipment, busses, emergency vehicles, boats, LRT, mining, power management systems for battery charging, fuel cells, battery backup, photovoltaic, wind and wave power systems where long life and high reliability are needed.All EVQ Series contactors meet RoHS and CE,CCC Conformance requirements.
