DESCRIPTION

The DTIPU20 Series of AC/DC switching mode single output power supplies provides 20 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. This series also has two types of AC inlet

connectors to choose from: Type A (IEC-320-C6) or Type B (IEC-320-C8). All supplies are UL 94V-1 compliant. All models meet FCC Part-15 class

B and CISPR-22 class B emission limits and are designed to comply with UL/cUL (UL 60950-1), TUV/GS (EN 60950-1) and new CE requirements.

All units are CEC and Energy Star compliant and are 100% burn-in tested.

SPECIFICATIONS: DTIPU20 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.
