enables soft starting of motors
Wide operating range
Voltage from 20 Vdc to 300 Vdc or 48 Vac to 265 Vac
Rated current up to 30 A
Limiting current up to 100 A
Integrated bypass relay
Applications
: Current limiter for capacitive loads, DC/DC converters, power supplies…
The LCA125 is an active current limiter with a time-delayed bypass relay, ensuring more efficient operation—
—than a simple thermal cut-off. It cuts off current spikes in the load during system startup
and dissipates no power during operation.
