Transformer speed controllers

TGRV

Transformer controllers are designed to change motor rotating speed by changing voltage.

TGRV B

Transformer controllers TGRV B for fans with own thermal contacts are designed to change motor rotating speed by changing voltage.

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.

TGRT

Transformer controllers TGRT are designed to change motor rotating speed by changing voltage. All controllers are with motors and transformers thermo protection function. 3 phase controllers are with power supply fault protection.

TGRTex for explosion proof fans

Transformer controllers are designed to change motor rotating speed by changing voltage. All controllers are with motors and transformers thermo protection function.

TGRT2r

Transformer controllers are designed to change motor rotating speed by changing voltage. All controllers are with motors and transformers thermo protection function.
