di/dt = 0.1A/µs, Vin = 48VDC, 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
Long Form Data Sheet.
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.
Recommended input fusing is a 5A HRC 200V rated fuse.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
Measured with no external Pi filter. Significant reduction possible with
external filter. See Application Note 118.
Start-up into resistive load.
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.
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’
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.
