DESCRIPTION
The PSSBU60 series of AC/DC switching mode power supplies provides 63 Watts of continuous output power in a compact, open
frame constructed design. This series has a universal input range with single, dual, triple, or quad outputs. 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)(4), ITS/GS (EN
60950-1), and new CE requirements. All units are 100% burn-in tested.
SPECIFICATIONS: PSSBU60 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.
