New improved version: now offers finer and more precise speed control over 1024 steps (previously 256). VDR added to the output to protect the regulator against voltage peaks generated by loads with a certain inductance. Triac triggering is zero-crossing with mains synchronism to avoid mains interference.
This external signal (0-10Vdc) or potentiometer operated AC motor speed controller uses Phase Angle Regulation (PAR) and a triac output (JST26Z-600BW or equiv.) and allows you to adjust the speed of 230Vac 50Hz single-phase "universal" motors as used in power drills, vacuum cleaners, etc and an operating load of up to 2500 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. The dc control signal input is electrically isolated from the mains. The board can be modified to accept an input signal range of 0 - 5Vdc by soldering a wire link across resistor R6.
Signal input operation can be set so the output is either directly or inversely proportional to the control signal.
Please see User Manual for full description.
PRODUCT SELECTION NOTES: Suitable for controlling most 230Vac 50Hz single-phase "universal" motors, light regulators, 230V signals through automation, 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.
Suitable for use with DIN-RAIL Mounting (Order Code C7589).
