The 422 DC servo amplifier is manufactured by Copley Controls. In the DC Servo Amplifiers series, it delivers ~10A continuous and ~20A peak output. It supports 24 to 180 VDC input and protects against short circuits and overtemperature. The wide inductance range of 200 µH to 40 mH and RS-422 interface enhance its flexibility.
