EM-217B (-H ) INVERTER FOR 230VAC 1-ph INDUCTION MOTORS

EM-217B is a frequency inverter for speed control of small 1ph induction motors. This device creates two output voltages with 90 deg. phase difference to each other, so theres no need for auxiliary capasitor like often with 1ph motors. The frequency output range is from 15Hz up to 80Hz. The output stage works with PAM princible and that way the EMC emissions are very low. The control can be done with voltage or mA signal or with potentiometer. The rotation direction can be changed with digital command. All cotntrol inputs are galvanically isolated from mains supply. Device has also a start and stop ramp for smooth operation. If needed, the stop ramp can be disabled for quicker stop. The EM-217B has self recovery mains fuse that offers a good immunity against the mains voltage spikes.
