The OMDC-MD series, available from Omega, is a compact programmable DC speed control with digital closed-loop feedback and LED display for DC motors rated to two horsepower. OMDC-MD features adjustable min/max speeds, adjustable acceleration/deceleration, and display options, including decimal point positions and intensity. The pulse input capacity for speed feedback is 50,000 pulses per minute (833 Hz). Its non-volatile memory provides programmable power-on initial settings, and allows all custom settings to be stored for future use. The OMDC-MD can be programmed to display any engineering unit of measure.
