TGRV2r

A three phase transformer controllers TGRV2r are designed to change motor rotating speed by changing voltage in five fixed steps. There are two control knobs: one for higher fan speeds and one for lower fan speeds.

A three phase transformer controllers TGRV2r are designed to change motor rotating speed by changing voltage in five fixed steps. There are two control knobs: one for higher fan speeds and one for lower fan speeds. Switching between the high and low settings is done by an external change-over contact, which could be a time relay or other device. Steps are fixed voltage and can be switched with two rotation switches. The steps are adjusted manually, using the control knobs on the front of the unit. There are two control knobs: one for higher fan speeds and one for lower fan speeds. Controller is reset by turning the switch to "0" position for 10 seconds, after which the unit restarts. Near the rotation switches TGRV 2 r controllers have voltage indication lamps. All controllers are with motors and transformers thermo protection function. All controllers have 230 VAC output for connection servo motors, actuators, heaters relays and etc. Supply voltage: 230V 50/60Hz.
