DESCRIPTION

The DTIPU30 series of AC/DC desktop switching mode power supplies provide up to 30 watts of continuous output power. All models have

a single output, universal input voltage range, and an operating temperature range of –20°C ~ +70°C. These supplies are also protected

against input surge current, over voltage, and over load conditions. All supplies are also UL 94V-1 compliant and include an IEC-320-C14

input connector for worldwide applications. All models 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. These supplies are 100% burn-in tested.

SPECIFICATIONS: DTIPU30 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.
