In the field of photovoltaic/energy storage, when the system voltage rises to 1500VDC, this series of products exhibit excellent performance, with lower temperature rise and greatly extended switching life, fully adapting to various harsh operating environments.
Certification
UL
CCC
Applications
Photovoltaic system
Energy storage equipment
Power battery system
High voltage inverter
Power contact
Parameter | Data |
Contact arrangement | 1 Form X（SPST-NO-DM） |
Contact polar | Without polarity |
Contact material | Copper or silver alloy optional, see “Part numbering system” |
Rated operating voltage | 1,500V DC |
Max. Continuous current（at 23℃） | 400A/500A/600A |
Common Questions of DC Contactors
1.Why is a step voltage recommended when applying voltage to a contactor coil?
If the voltage rises or drops slowly, it will cause more contact jitter when the contacts close or open, resulting in unstable contact and easily leading to a sharp reduction in the relay's lifespan.
2.Why does the contactor heat up even though no current passes through the main contacts after they are closed?
After the main contacts of the contactor are closed, the contactor coil continues to work. The heating phenomenon at this time is caused by the coil operation.
