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.

BIT continuously monitors the status of all I/O during normal operations and is totally transparent to the user. SBC resources are not consumed while executing BIT routines. This simplifies maintenance, assures operational readiness, reduces life-cycle costs and – keeps your systems mission ready.
One-Source Efficiencies
Eliminate man-months of integration with a configured, field-proven system from NAI. Specification to deployment is a seamless experience as all design, state-of-the-art manufacturing, assembly and test are performed – by one trusted source. All facilities are located within the U.S. and optimized for high-mix/low volume production runs and extended lifecycle support.
Product Lifecycle Management
From design to production and beyond, NAI’s product lifecycle management strategy ensures the long-term availability of COTS products through configuration management, technology refresh and obsolescence component purchase and storage
