DESCRIPTION

The PSSUU100 series of AC/DC switching mode power supplies provides 100 Watts of continuous output power in a compact, U-

frame constructed design. This series has single output supplies with a universal input range of 90~264VAC. These units are ideally

suited for use in 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 60950-1),

TUV/Bauart (EN 60950-1), and new CE requirements. All units are 100% burn-in tested.

SPECIFICATIONS: PSSUU100 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.
