General
These miniaturised 20W* switched mode power supplies are available as Wall plug-in, Desk Type or as Open Frame versions. The Wall plug-in version is delivered with a Europlug as standard (ESL...). Units with plugs for UK (ESK...), North America and Japan (ASN) are also available. The input voltage range on the units for Europe (ESL... and ESK...) is 180VAC...264VAC, for North America and Japan (ASN...) 90VAC...132VAC. The desk- and Open Frame versions (USD... and USP...) are generally delivered with wide range input of 90VAC...264VAC. The mains frequency range is 47...63Hz for all models.
The desk versions are fitted with a IEC 320 socket.
The Open Frame units are also available for PC-Board mounting (USE...).
Safety:
Complies with UL 1950, 3101-1, 544, 2601, CSA 22.2 #234, 125, 601, 1010.1, EN 60950 (IEC 950), 41003, IEC 601, 1010.
EMI: Complies with EN 55011, EN 55022, VFG 243 Class B with a 6dB�V margin when tested with resistive load and FCC part 15 class B.
Applications:
Test & measurement equipment, Communication units, Computer peripherals, Information systems, and Medical products. The output cord is 185cm long. Single output units (except 3.3V) are provided with a 5,5/2,5mm � DC- output plug (+ = centre), all dual, triple and 3.3V output models are provided with a 6 Pin Mini-DIN plug. Other plugs and cords on request.
Options: Remote Sensing:
Provides regulation for main output within 2% of the nominal voltage.
Overvoltage:
a) Shut down without latching - The unit will shut down when the overvoltage is activated at 130% of the nominal value and automatically recover when the fault is removed.
b) Shut down and latched - The unit will shut down when the overvoltage is activated at 130% of the nominal value and remain shut down even if the fault is removed. The unit can only be reset by cycling the input power.
