DESCRIPTION

The DTIPU45 series of AC/DC switching mode power supplies provide up to 50 watts of continuous output power. Models have a universal

input range and are available with single, dual, or triple outputs. Some features include -20°C ~ +70°C operating temperature and input

surge current, over voltage, and over load protection. All supplies are UL94V-1 compliant and include an IEC-320-C14 input for worldwide

applications. These supplies meet FCC Part-15 class B and CISPR-22 class B emission limits and are designed to comply with UL/c-UL

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

SPECIFICATIONS: DTIPU45 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.
