SAFETY &EMC
(Note 6)
converters has been designed for a wide range of
applications including communications, industrial systems
and battery powered mobile equipments. Key features are
high power density (12W in a 2“x1“x 0.4“ package) and
ultrawide input ranges of 9 – 36 VDC and 18 –75 VDC.
Other features of this converter are internal filtering
according to EN 55022, level A, safety approval to EN
60950 and UL 1950, wide operating temperature range
and remote on/off (opt.).

NOTE
1. All parameters NOT specially mentioned are measured at 12,24,48VDC input,
rated load and 25 of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted
pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Short circuit not more than 60 second.
5. DC source wires 5cm, an input external al capacitor 47 ~ 100uF is required.
6. The power supply is considered a component which will be installed into a final
equipment. The final equipment must be re-confirmed that it still meets
EMC directives.
