CR0020 - AC Motor Speed Controller (0-10Vdc Signal/Potentiometer) Module (230Vac/50Hz, 750W)

This external signal (0-10Vdc) or potentiometer operated AC motor speed controller uses Phase Angle Regulation (PAR) and a triac output and allows you to adjust the speed of 230Vac/50Hz single-phase induction motors as used in power drills, vacuum cleaners, etc and an operating load of up to 750 Watts.

Motor speed adjustment is from 0 to 100% is achieved using either an external 10K potentiometer (not included) or a 0-10V dc control signal. Please note that the dc control signal input floats at mains potential and may not therefore be suitable for some applications like connection to DMX systems (see CR0026 for an alternative option).

Signal input operation can be set so the output is either directly or inversely proportional to the control signal.

Please see User Manual below for full description.

PRODUCT SELECTION NOTES: Suitable for controlling most 230Vac/50Hz single-phase induction motors, light regulators, 230V signals through automatisms, etc… NOT suitable for use with synchronous AC motors, capacitor-start/run AC motors or inductive loads like halogen or PL lamps, neon, etc.. Ask the manufacturer to confirm if their motor is suitable for control using a Phase Angle Regulation (PAR) style controller BEFORE you buy this product! The motor controller should have an output load capacity at least 25% above the motors peak power requirement. Please do NOT rely on motor rating plates for power consumption figures as they often quote average not peak power. You should verify the actual peak power at start-up and under full load before selecting an appropriate size motor controller.

Please see CR0021 for a 1500W version of this product.
