The Cosel FETA2500B-36 is a single-output AC/DC front end converter delivering 36V at 55A for a total of 1980W. Designed for rack mount installation, it is suitable for ITE (commercial) applications.
Operating from an AC input of 170-264VAC (single phase), it achieves up to 91% efficiency at 50% load and 90% at full load. Power factor correction (PFC) is included, with a typical power factor of 0.98 at full load. The converter provides 3kV isolation voltage and complies with safety standards UL62368-1, CSA62368-1, and EN62368-1.
Output voltage is adjustable from 28.80V to 39.60V. Protection features include overcurrent protection (105-120% of rated current with automatic recovery) and compliance with SEMI F47. Ripple and noise are limited to 360mVp-p at 0-50°C. The unit measures 340.0mm x 102.0mm x 41.0mm (13.39" x 4.02" x 1.61") and operates over -10°C to 71°C with derating.
