Frequently Asked Questions
Does it support continuous operation above 100A?
Yes, the 150A rated current design makes this high current relay ideal for 24/7 operation in demanding environments.
How to wire the double coil latching relay?
The L2 model provides SET/RESET dual control terminals (see wiring diagram on Page 3 of specs). The state is maintained after pulse driving.
Is it suitable for charging station PDUs?
Absolutely. This PDU relay is optimized for charging applications, with our reference design showing integration with 8-gun charging modules.
