Motor Drives are available with a full sweep time of 4, 8, 15, 30, 45, 60, 90, or 120 seconds fitted with a “Stepper Dot” AC synchronous motor, rated for 230 volt / 240 volts single phase 50Hz AC supply.

• Brand: Dimmerdot / Greendot
• Delivery: Ex Stock / Next day
• Design: Motorised
• Certification: IS 5142

Motorised Dimmer Dots are available as a complete Unit with a standard sweep time of 15 seconds, other sweep times are also available. Motorised Dimmer Dots range from 8 Amp upwards.
Motor drive units are also available separately.
These motors start, stop and reverse instantly. The motor drives are fitted with micro switches for travel end limits, to cut off the motor supply in extreme positions. The covered motorised units are fitted with push button controls for raise and lower operations. These push buttons can be relocated at a different location for remote control or can be easily controlled from an external PLC or computer.
Variable dwell cams can be fitted for fixed range or sequence operations and have to be indicated at the time of ordering.
Special motor drives fitted with DC motors or low voltage motors can be supplied to special orders. Special assemblies can be provided with switching and relays, giving a programmed automatic sequence of operations.

Common Applications include:

• Control of AC voltage and current in testing and developing work.
• Over voltage and under voltage tests.
• New or faulty electrical equipment – appliance testing. Gradual application of voltage to detect for any high fault current.
• Lighting control in theatres, auditoriums, photographic studios, dark rooms, hotels, restaurants, rearing houses, etc.
  (Not recommended for discharge on hot-cathode fluorescent lighting).
  DC voltage and current control of rectifiers, such as rectifiers for
• Electroplating, Electrowinning, Anodising, Precious Metal Recovery, Hydrogenation,
• Cathodic Protection, Battery plate forming.
• Voltage control in DC power supplies and constant current supplies.
• Regulated Output voltage control for Motor Servo type AC Stabilisers and Automatic Stabilisers
• Voltage control for meter calibration, phase-angle control in the calibration of Watt meters and Power factor meters.
• Motor speed control.
• Control of electric heaters, furnaces and ovens in laboratory, pilot plant and production lines.
• Current control for testing of circuit breakers, relays, current transformers, etc.
• Testing of magnetic materials.
