Transformer fan speed controllers RV.. (1x230V) with cable glands (GL) or grommets (GR)

Transformer controllers RV.. GL/GR are designed to change motor rotation speed by changing the voltage. Controllers have an overheating protection function. The steps have fixed voltages and are switchable with a rotary switch. A single-speed controller can control multiple motors if the total of all motors' power consumption does not exceed the maximum current. The transformer controllers are produced with cable glands (GL) or grommets (GR) according to a client's requirements. The cable seals are designed to protect cables and insulate electrical wiring, cables, and other components from damage and abrasion.
