ETSA4801875UD-P6P-SZ Description

Short technical summary and product information.

The CUI Inc. ETSA4801875UD-P6P-SZ is an AC/DC desktop power adapter delivering a regulated 48Vdc output at up to 1.875A (90W total). Designed as a Class II (double-insulated) desktop supply, it accepts a universal input of 90–264Vac at 47–63Hz and achieves Level V efficiency with a maximum no-load power consumption of 0.5W.

 

Electrical protections include output over-voltage protection (60Vdc shutdown), short-circuit protection with auto restart, and 3000Vac input-to-output isolation. The adapter maintains ±5% load regulation and operates from 0°C to 40°C with 20–80% non-condensing humidity.

 

Mechanically, the adapter measures 149.4mm x 62.4mm x 33.5mm and is equipped with a 39.4-inch (1.0m) output cord terminated with a 2.5mm ID x 5.5mm OD barrel plug, positive center polarity. The input connector is an IEC 320-C8 (figure-8) style; an input cord is sold separately.

 

Safety approvals include UL 60950-1, EN 60950-1, IEC 60950-1 carrying UL/cUL, GS, and PSE marks. EMC compliance covers FCC Part 15 Class B and EN55022 Class B for both conducted and radiated emissions.
