STVS1
230 VAC TRANSFORMER CONTROLLER WITH
ANALOGUE INPUT
PRODUCT DESCRIPTION
The STVS1 series of transformer fan speed controllers regulate the speed of
single-phase voltage controllable motors in five steps by varying the output
voltage according to an 0—10 VDC analogue input signal. They are equipped with
autotransformer(s) and feature TK monitoring for thermal motor protection. The
controllers up to 7,5 A are available in plastic enclosure, while the models above 7,5
A are available in a metal enclosure.
