Hv DC Contactor
The contactor applications include battery
power, the inverter capacitor pre-charging, the DC
power control, circuit protection, and other electric
vehicles power control, while widely used in
uninterruptible power supplies and other
electronic control system.
PART TWO:Product Facts
1. High current and high voltage capability
Epoxy encapsulated contacts room filled with
inert gas, combined with the magnetic arc
blow, can cut off 900VDC load.
2. Compact structure and Low noise
As a result of the contacts sealed in inert gas
room, even if the contact gap is very small, but
also to ensure efficient and safe cutting, low
3. Coil Economizer
1.7W hold power @12VDC and it limits back
EMF to 0V.models.
4. Small Arc Gap
Non-arc gap structure, so the volume can be
Arc is sealed in a space to ensure that
products with safety.
6. Reliable Contacts
Contact unit is sealed in an inert gas, so
regardless of the environment, can maintain a
stable contact resistance.
7. No special installation required
Movable parts have a light weight and large
reaction force, so affected by gravity is small.
There are two installation methods sides and
bottom, no special requirements on the installation
8. Multiple Uses
Standard applications include: Battery
switches and standby equipment, DC voltage
power control, electrical safety protection and so
9. Compliance with EU RoHS directive (2002/95/EC)
10. Load Polar Conditions
Loaded with two kinds of polar and non-polar.
