DIN RAIL PHASE-CUTTING VOLTAGE REGULATOR FOR SINGLE-PHASE FANS

The SPM regulator is a module that can be controlled by the DIN NANO FSC and allows the single-phase fan speed to be varied up to 8A. It uses the phase-cutting principle to adjust the effective output voltage from 0 to 230 Vac, according to the 0-10 Vdc command signal applied on input.
The output can be adjusted manually by connecting an external 10 KOhm potentiometer to the board. The regulator is fitted with a fuse, which can be easily inspected and replaced, which guarantees short-circuit protection.
It is recommended to verify that the connected motors are suitable for use with phase-cutting regulation.
