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.

NOTES
1. The DTIPU20 Series is designated as DTIPU20x-y where x represents the type of AC input inlet connector which can either be
A
(IEC-320-C6) or
B
(IEC-320-C8); y can be 102, 103, 104, 105, 106, 107, 108, 109, 110 or 111 for output voltage.
2. The output voltage is specified as a range (Ex: 40 ~ 48VDC); the preset voltage will be set as standard models if nothing different is
requested. Please contact factory for ordering details.
3. To meet the total regulation specifications all models must use an AWG#18/4FT output cable. The regulation will change if the output
cable is modified.
4. The “*” represents TUV/PSE approval. Models with output voltages under 30VDC have been approved by TUV/PSE.
5. Optional output connectors are available. Please call factory for ordering details.
