Description

Transformer controllers are designed to change motor rotating speed by changing voltage. All controllers have thermo protection function. When power supply recovered, controller did not switch on previous step until is switched OFF and ON to desired step. Voltage steps are changed with rotary switch. Controllers also have power indication LED. All controllers have 230 VAC output for connection of servo motors, actuators, heaters relays and etc. To one controller more than one motor can be connected, if total current of all controllers is less than maximum controller current. In this case all motors thermo protections must be connected in series. RV-B controllers don't have thermal contacts connection.
