This product is widely used in the fields of photovoltaics and energy storage. It adopts a double coil innovative design and has a set of feedback contacts built-in. The main contacts achieve non-polarized connection, greatly improving the flexibility of adaptation. At the same time, the product has excellent anti-interference ability and is still stable and reliable in the face of complex electromagnetic environments.
Features
Epoxy packaging, the contacts are protected by nitrogen, preventing oxidation, strong cooling arc capacity.
High-voltage, high-current control capable.
Compact & low operating sound.
Safety and high contact reliability.
Can be installed in any direction.
Not freezing and condensing at low temperature.
Certification
CCC
UL
CE
TUV
Applications
DC Fast charging equipment
Energy storage equipment
Power battery system
High voltage inverter

Operating voltage range | 10.2-13.2V DC | 20.4-26.4V DC |
〈05 The product has been configured with coil surge absorption circuit (TVS), buyers do not need to configure.
〈06 Because the DC contactor is operated by a coil that changes resistance with temperature: When the temperature is higher than 23℃, coil resistance, pick-up voltage and drop-out voltage will be higher than the nominal value, and the coil power will be lower than the nominal value. When the temperature is below 23℃, coil resistance, pick-up voltage and drop-out voltage will be lower than the nominal value, and the coil power will be higher than the nominal value.
〈07 For pick-up testing of DC contactors with dual coil, the voltage should not rise slowly, and the voltage should be applied not less than the nominal pick-up voltage immediately. Otherwise, the DC contactor will not pick-up.
〈08 Contactor has two coils. Both are used for pick-up, and then in approximately 75 milliseconds, one coil is electronically removed from the coil drive circuit. The remaining coil supplies low continuous hold power sufficient for the contactor to meet all its specified performance specifications. This provides the lowest coil power.
