TELECOM SPECIFICATION
Central office interface A
ETS300-132-2 input voltage
and current requirements
(<20mΩ short)
Continuous
Non-latching clamp
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.
2
The EXQ50 meets level A and level B conducted emissions only with
external components connected before the input pins to the converter.
See Application Note 120 for details.
3
Recommended input fusing is a 3.15A 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.
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
EXQ50-48S3V3-R.
8
This parameter is calculated at worst case line, load, temperature and
initial settings.
9
This is inclusive of the output trim range. If 6.0% trim-up is used, for
example, then only 4.0% output sense is available.
10
Maximum, not typical, specification.
CAUTION: Hazardous internal voltages and high temperatures.
Ensure that unit is not user accessible.
