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.
