64PW2

VME PWM Servo Motor Drive / Amplifier Board

NAI’s 64PW2 is a 6U VME Servo Motor Drive/Amplifier Board featuring a dual, four-quadrant, bi-directional, PWM servo amplifier. Specifically targeted for DC servo motor applications, this board has an amplified power stage that uses a Pulse Width Modulation (PWM) control signal to provide motor control for both brush and brushless motors. Each motor drive accepts a 65 VDC power input and provides a 5 Amp maximum continuous current output (8.5 Amp peak).

In addition to numerous safety features, this conduction-cooled board includes Background Built-In-Test (BIT) for continuous checking and reporting on the health of each channel. Specifically designed for rugged defense, commercial aerospace, and industrial applications, the 64PW2 supports optional RS-422, A/D, D/A, or dual Resolver-to-Digital interfaces.
