MDC servo amplifiers for brush-type motors up to 850 oz-inches are MOSFET, pulse-width-modulated, providing four-quadrant control in torque, velocity, and voltage modes. MDC servo amplifiers are available in two voltage ranges, 21 to 80V dc and 40 to 180V dc, and in two current ranges, 6 and 12A. Additionally, an onboard 5V dc 250 mA supply powers an encoder. Measuring 4.43 X 7.3 X 1.6 inches, these inaudible 20 kHz switching amplifiers are available in custom performance ranges and packaging.
