919D2PR Panel Mounted Bi-Directional Variable Speed Regulator




A panel mounted speed regulator that features a constantly variable, bi-directional output. These units are designed to be used with miniature and sub-miniature motors and are suitable for a range of applications. The motor can be powered from a DC source, either battery or transformer recitifier (transformer rectifier must have a non-digital output). PWM circuitry is employed which varies the output pulse width to vary the motor speed whilst still maintaining a constant output voltage. Motor torque output is also maintained with the assistance of the PWM circuitry.

  • Forward and reverse PWM speed regulator
  • Easy installation - unit panel mounted through 9.5mm hole
  • Electrical connection via screw terminals
  • 6 to 15V DC operation (from smooth non-digital DC input)
  • Output 0 to 100% of input voltage
  • Compact construction - board size 66 x 58mm
  • MFA/Como 919D2PR type


Note: Output may not zero motor speed in no load conditions.

Questions





Question by paul | Product code: 37-1141
5th March 2012

Qhi can this module be used to power a model train using a 12v dc power supply from maplin to power it
AThanks for your enquiry Paul. This will handle 12V DC up to 3A non-digital input, but it will produce a PWM output.
