2 YEAR WARRANTY

EXQ125 Series

Single output

• Ultra-high efficiency topology, 91% at 3.3 V,

88% typical at 1.8 V

• Industry standard footprint

• Wide baseplate temperature, -40 °C to +100 °C

• 90% to 110% output trim

• No minimum load

• Overvoltage protection

• Remote ON/OFF

• Available RoHS compliant

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 Vdc to 75 Vdc and are available in output

voltages of 12 V, 5 V, 3.3 V, 2.5 V, 1.8 V, 1.5 V and 1.2 V. 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 (TÜV Rheinland) and UL/cUL1950, the EXQ125 reduces compliance costs

and time to market.

All specifications are typical at nominal input, full load at 25 °C unless otherwise stated

Notes

1 di/dt = 0.1 A/µs, Vin = 48 Vdc, Tc = 25 °C, load change = 0.5 lo max. to

0.75 lo max. and 0.75 lo max. to 0.5 lo max. Deviation varies by model, see

Longform Datasheet.

2 The EXQ125 meets level A and level B conducted emissions only with

external components connected before the input pins to the converter.

See Application Note 118.

3 Recommended input fusing is a 5 A HRC 200 V 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 Contact the factory for Modified Standard pin length products.

8 TSE RoHS 5/6 (non Pb-free) compliant versions may be available on

special request, please contact your local sales representative for details.

9 NOTICE: Some models do not support all options. Please contact your

local Artesyn representative or use the on-line model number search tool

at http://www.artesyn.com/powergroup/products.htm to find a suitable

alternative.

CAUTION: Hazardous internal voltages and high temperatures.

Ensure that unit is not user accessible.
