DESCRIPTION

The PSSBU120 series of AC/DC switching mode power supplies provides 120 Watts of continuous output power in a compact,

open frame constructed design. This series has a universal input range with single, dual, or triple outputs. These units are ideally

suited for use in CRT terminals, disc drive systems, microprocessor based systems, portable equipment, and many other

applications. All models meet FCC Part-15 class B and CISPR-22 class B emission limits. These supplies also comply with UL/cUL

(UL 60950), TUV/GS (EN 60950), and new CE requirements. All units are 100% burn-in tested.

SPECIFICATIONS:

PSSBU120 Series

All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.

We reserve the right to change specifications based on technological advances.
