EM-217B (-H ) INVERTER FOR 230VAC 1-ph INDUCTION MOTORS ■speed control -direction change ■start ramp -slip compensation -isolated control EM-217B is a frequency inverter for speed control of small 1 ph 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 1 ph 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 TECHNICAL DATA Dir. input level 4-30V =0N / <1 V =OFF Direction change delay 0.2s EMC tested for household / light industry

-Supply must be switched off when connecting input range: V / mA / Potentimeter -Turn compensation trims to recommended position (If motor is unknown, set both trims to min. position) - Installation of this device is allowed only for person who has competence for mains voltage voltage installation like a licensed electrician. - The slip compensation adjustments are on mains voltage side. So use allways Insulated tools. Turn supply on and start to Increase speed set voltage. Motor should start to run smoothly from low speed to high speed. Try to change direction when motor is running at high...
