Motor speed regulator HRB 3 3A

Transformer motor speed controller HRB 3

Transformer regulators are designed to change the rotational speed of motors by changing the voltage. The regulators have a function to protect the transformer from overheating. All controllers have a 230 VAC output for connecting actuators, heaters, relays, integrating the operation of accessories with the operation of the fan. More than one fan may be connected to a single controller, provided that the total current of all motors does not exceed the regulator's allowable value.
