ELECTRONIC SPEED REGULATOR RVM4E FOR SINGLE PHASE ASYNCHRONOUS MOTORS IP55 PROTECTION CASING
The regulator is formed by circuits incorporating triac controlled by an external command, for the continuous motor speed variation from 40 up to 100% of 220V motor nominal speed, with 4 Ampere max nominal current. The regulator has been made specially for motors connected with fans, aspirators or pumps. It may also be used as a voltage variator for any ohmic load. See that the min. voltage regulation starts from 30-40% of line voltage. The regulator can change voltage from 0 up to max line voltage, upon request. It is housed in a plastic container: on the frontal panel are situated the switch, the hand grip command for speed variation, the trimmer for min. speed regulation and the 10 Ampere fuse, for regulator’s internal circuit protection.
