regolatore di velocità rvm12e


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 12 Ampere max nominal current, for 3 wires connection (fig. 1) for 2 wires connection (fig. 2). 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 15 Ampere fuse, for regulator’s internal circuit protection.


For wall installation, fasten the regulator with 4 screws.


We recommend to follow carefully the instructions, in order to avoid regulator or motor damage. Connect wires to the supply line and to the motor as shown on fig. 1, if a motor’s 3 wires connection is possible see that the regulator can work only if the voltage regulator circuit (terminals U1-U2) supplies the motor coil-winding without condensator. Connect as shown on fig. 2, if at the motor output only 2 wires are available or for ohmic load: in that case terminals U1 and U2 are only used. Supply the regulator with regulation hand grip at min. (counter-clockwise turned). Motor supply: about 75V. With the trimmer on the frontal panel it is possible to regulate min. voltage from 75V up to 180V. Make sure that on min. voltage motor runs. If not, increase voltage using the trimmer. Turn the regulation hand grip clockwise: the motor speed will increase up to nominal speed. An internal trimmer (sealed) allows to reduce min. voltage under 75V. It’s recommended not to touch it, as under 75V the motor could not run and therefore be damaged. In order to protect eletrically the regulator-motor unit, it’s necessary to install a suitable amperometer protection on the supply line.
