68PW1
3U OpenVPX SOSA™-aligned PWM Servo Motor Drive
The 68PW1 is a 3U OpenVPX SOSA-aligned (basis, Snapshot 2) single-axis PWM servo motor drive that can be configured with closed loop feedback measurement options including Hall, Resolver/Synchro or Encoder. The PWM drive provides programmable PWM output drive (up to 65 V @ 10 A continuous) from a single +28 VDC input source. Ideally suited for rugged Mil-Aero applications, the 68PW1 delivers off-the-shelf solutions that accelerate deployment of SWaP-optimized systems in air, land and sea applications.
