Unfiltered SCR motor speed controller operates between 115V AC or 230V AC line. It has switchable 0-90V/0-180V(DC) output. EMF back feedback maintains speed regulation more than 2%. It can calibrate control for variable motor sizes as it dip switches comfortably. It comes with NEMA4 enclosure for dirty & wet environments.

Trim pots are provided on the PC board to adjust torque limit, maximum & minimum speed limits, acceleration & deceleration time and also for speed regulation, . A speed pot in front of the enclosure can be used for adjusting the speed. To facilitate quick line and motor connection, terminal block is provided inside the enclosure.

Line fuses inside enclosure. The toggle switch which is placed on the front panel is used for AC power ON/OFF. Lamp on enclosure indicates, when the power is on. EMI conduction is reduced by inside enclosure line filter.
