o
Current control for inductive actuators at 24 V (10 to 36 V)
High efficient current control up to 1 A
Power saving and power dissipation reduced switching
Individual setting of energising and hold current
Monitoring of coil current, supply voltage and temperature
Status indication via LED or logic output
Contact preserving switching of relays synchronous to the
mains
Shutdown with overtemperature and undervoltage
Fast demagnetising due to 15 V countervoltage
High PWM frequency with spreading for low EMI
Energising time of 50 ms prolongable with external capacitor
