New AC speed controller for Rittal Fan and Filter products

Supplied with a temperature sensor that can be positioned within the enclosure to monitor particular hot spots, the device controls the fan speed based on a manually adjusted set point P1 to ensure optimum cooling and noise reduction is given at all times. A minimum speed set point P2 allows full control over cooling within the enclosure.

A visual LED and an alarm relay will give indication of either over temperature, fan fail, sensor fail or short circuit and interruption to the supply cable or fan cable.
