• Industrial PCs
• LED Lighting Applications
The DTAPU41 series of AC/DC desktop power supplies provides up to 40 Watts of
continuous output power in a 4.21 x 1.85 x 1.19 inch package. This series consists of
single output models ranging from 5VDC to 48VDC with a 90~264VAC input voltage
range and an IEC-320-C14 AC inlet connector. Some features include high efficiency up
to 90%, -40°C to +70°C operating temperature range, and over current protection. All
units are UL 94V-1, RoHS, and CEC & Energy Star Level V compliant. This series also meets
FCC Part-15 class B and CISPR-22 class B emission limits. All models meet new CE
requirements and have UL/cUL (UL 60950-1: 2nd edition) and TUV/GS (EN 60950-1: 2nd
edition) safety approvals. All units have been 100% burn-in tested.

NOTES
1. The output voltage is specified as a range (ex: 40~48VDC); the customer must specify what they would like the output voltage set at.
2. Models DTAPU41A-102~105 need to use AWG#16/4FT output cable in order to meet the total regulation specified.
Models DTAPU41A-106~111 need to use AWG#18/4FT output cable in order to meet the total regulation specified.
The regulation and efficiency will change if a different output cable is used.
3. Optional output connectors are available for this series. Please call factory for ordering details.
