Transformer speed regulator RV ..B-2

Transformer controllers RV ..B-2 are designed to change the motor rotating speed by changing the voltage. Regulators are with the transformer's thermoprotection function. Steps are with a fixed voltage and are changed with a rotary switch. Regulators are equipped with 2 rotary switches. Rotary switch selection can be made with an external signal. In this case can be selected one of set speeds. To one controller, more than one motor can be connected if the total current of all motors is less than the maximum controller current.
