The EXQ125 is a new ultra-high efficiency, open frame, isolated converter series in
an industry standard quarter-brick footprint that provides up to 100 watts of output
power. The EXQ125 delivers very high output current at low voltages, and excellent
useable power density for today's high end applications. The seven models in the
series feature an input voltage range of 33 to 75VDC and are available in output
voltages of 12V, 5V, 3.3V, 2.5V, 1.8V, 1.5V and 1.2V. The output voltage on each
model is adjustable from 90% to 110% of the nominal value. The EXQ125 series
also has a remote on/off capability. Overcurrent and overvoltage protection features
are included as standard. With full international safety approval including EN60950
(TV Rheinland) and UL/cUL1950, the EXQ125 reduces compliance costs and time
to market.
All specifications are typical at nominal input, full load at 25C unless otherwise stated

Recommended input fusing is a 5A HRC 200V rated fuse.
4
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
5
Measured with no external Pi filter. Significant reduction possible with
external filter. See Application Note 118.
6
Start-up into resistive load.
7
Active low remote On/Off is available. Standard product is active high.
When ordering active low parts, designate with the Suffix `-R',
e.g EXQ125-48S3V3-R.
8
When ordering 0.145" pin lengths designate with the Suffix `-N', if the
product is already a `-R' suffix product then the suffix will be `-RN'
9
When ordering 0.110" pin lengths designate with the Suffix `-K', if the
product is already a `-R' suffix product then the suffix will be `-RK'
CAUTION: Hazardous internal voltages and high temperatures.
Ensure that unit is not user accessible.
