EM-213 is a 1-quadrant power controller. The controller uses PWM principle with high efficiency.
The PWM frequency can be set to high or low mode. High frequency is used with inductive (motor)
load and low with resistive (lamp) load. The output of the device is compensated against power
supply changes, so the device can be used succesfully with unregulated power supply. Output is
overload (overheat) protected. The protection recovers by itself as temperature decreases. Control
of device is done with analog voltage signal 0-5V or more, range of this signal is adjustable.
EM-213 also includes a soft-start ramp with adjustable time.
FEATURES:
• Low cost
• High efficiency
• Operating voltage compensated
• For resistive or inductive loads
• Applications: motor speed control, lamp dimmer
• Rail base fittable
