PWM 继电器/螺线管驱动器, 宽操作电压范围 (1 A)

PWM Relay/Solenoid Driver for a Wide Operating Voltage Range (1 A)

Features      

• Current control for inductive actuators at 24 V (10 to 36 V)

• High efficient current control up to 1 A

• Switching with power saving and reduced power dissipation

• Individual setting of energising and hold current

• Contact conserving switching of relays synchronous to the mains

• Monitoring of coil current, supply voltage and temperature

• Shutdown with overtemperature and undervoltage

• Status indication via LED or logic output

• Fast demagnetising due to 15 V countervoltage

• High PWM frequency with frequency spreading for low EMI

• Energising time of 50 ms prolongable with external capacitor

Applications

• PWM driver for inductive loads (e.g. relays, electrovalves)

• Relay low-/high-side switch
