•
The DTEPU20 series of AC/DC desktop power supplies provides up to 20 watts of continuous output power. This
series consists of single output models with output voltages ranging from 5~50VDC and a wide operating input voltage
range of 90~264VAC. All units are UL 94V-1, RoHS, and CEC/Energy Star level VI compliant and meet FCC Part-15
class B and CISPR-22 class B emission limits. The DTEPU20 series also meets new CE requirements and has
UL/cUL (UL 60950-1: 2nd edition), TUV/GS (EN 60950-1: 2nd edition), FCC, CB, and CE safety approvals. The
DTEPU20 series has three types of AC inlets available: IEC-320-C14 (Type A), IEC-320-C8 (Type B), and IEC-320-C6
(Type C). All units have been 100% burn-in tested.

DTEPU20B-102~107 are required to use AWG#18/4FT output cable.
DTEPU20B-108~111 are required to use AWG#20/4FT output cable.
The electrical characteristics will be changed by modified output cable.
Output can provide up to peak load when the power supply starts up. Staying in more than rated load continually is not allowed.
Each output is checked to be within voltage accuracy in 60% rated load condition.
Line regulation is defined by changing ±10% of input voltage from nominal line at rated load.
Load regulation is defined by changing ±40% of measured output load from 60% rated load.
Ripple & Noise is measured by using 20MHz bandwidth limited oscilloscope and terminated each output with a 0.47uF capacitor at rated load and
nominal line.
Hold up time is measured from the end of the last charging pulse to the time which the main output drops down to low limit of main output at rated
load and nominal line.
