Intel / Wind River / EST PUP55-23-M5 VisionICE / VisionICE II Power Supply

The PUP55-23-M5 is an AC/DC switching power supply engineered to deliver stable, efficient power to Intel/Wind River/EST VisionICE and VisionICE II emulation systems. Operating from 85 to 264 VAC at 47 to 63 Hz, this compact unit produces 40 to 55 watts of continuous output power with 70% minimum efficiency on single outputs ≥10V. Built in a 94V-1 rated polyphenylene-oxide enclosure with worldwide IEC 320 AC input, the supply incorporates active overvoltage and overcurrent protection, achieving 450,000 hours minimum MTBF at full load.
