100 Watt
Switchers
•75% typical efficiency
•EN55022-A conducted
•Up to 4 outputs
•Compact 5.0” x 3.3” x 1.5” size
•UL, cUL, TUV and CE
•Optional cover
•Available with 24Vdc and 48Vdc

•Available with EN55022-B
filtering (US100B Series)
•Available with medical safety
approvals (US100M Series) The US100 series is one of the industry’s smallest 100W
switchers. Measuring only 5” x 3.3” x 1.5”, this series of tiny
giants deliver up to 100W continuous or 120W peak power
from one to four outputs. The 90-250Vac universal input allows
them to be used worldwide.
The US100 is one of the flexibility series. In addition to the
models listed on this sheet, many potential models are available
that include full safety agency approval and do not require any
non-recurring engineering (NRE) charge. Prototype delivery is
just a few weeks.
Flexibility options include a cover and adjustable post regulators
on V3 and/or V4 outputs. Output voltage options are given in
the table below. Fully custom models are also available. Contact
the factory for details and for information on EN55022-B
filtering, medical approval and power fail/power good detect.
US100 models are also available with 24Vdc or 48Vdc inputs.
Please see the DP100 Series data sheet for details.

Notes:
1At least 20% of maximum output current
(Im) is required to maintain stated
regulation. Supply remains on at zero load,
but regulation is not guaranteed.
2Convection cooling, 70W maximum
3Forced air cooling, 100W maximum
4Peak output, 30 sec max, 50% load
required on V1
5Isolated output
6The US100 series allows very fast flexible
modified standard design changes within
these parameters without non-recurring
engineering charges and while retaining
safety agency approvals. For medical
models (US100M Series), maximum
output voltage for V1, V2, V3 and V4 is
+24V. Please contact the factory for details.
