DESCRIPTION
The PSMHBU31 series of AC/DC medical power supplies provides 30 Watts of continuous output power in a compact, open frame
constructed design. All models have a single output and a universal input. These power supplies meet FCC Part-18 class B and CISPR-11
EN55011 class B emission limits. They are also designed to comply with UL/cUL (UL60601-1), TUV/T-mark (EN60601-1) and new CE
requirements. This series is best suited for use in Home health care applications. All models are 100% burn in tested.
SPECIFICATIONS: PSMHBU31 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.
