Product description

The GTH series of transformer fan speed controllers regulate the rotational speed of single-phase voltage controllable motors by varying the output voltage according to the measured temperature. These controllers can be used for heating or cooling applications. They are equipped with autotransformer(s) and control AC fan speed in automatic or manual mode. In automatic mode, the fan speed is automatically adjusted in five steps according to the measurement of the external passive temperature sensor (PT500 probe, not included). In manual mode, it is possible to select one of the 5 indicated fan speed positions via the integrated control switch. This control switch has 7 positions: OFF, automatic mode and 5 different speed selections for manual mode. When the setpoint is reached, the fan will be deactivated in both automatic and manual mode. The unregulated output is activated together with the motor and can be used to control a valve (e.g. supply valve for heating or cooling water). The enclosure is designed for surface mounting in indoor environments (IP54). Available voltage taps: 0-(80)-110-140-170-230 VAC. Maximum motor current: 2,5 A.
