FASEC 43/43C is designed for speed control and is particularly suitable for fan applications.

The standard version provides a triac output to control a load up to 2.5 A, while a special version ensures control up to 7 A.

The latter version contemplates the use of an LC filter fitted outside the instrument. Such filter is necessary to reduce conducted emissions and radio frequency due to the type of regulation.

The temperature probe is galvanically insulated from the supply voltage.

Another special model is available to control speed in ZHIEL motors.
