Notes
1 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 EXB250 meets level A and level B conducted emissions only with
external components connected before the input pins to the converter.
See Application Note 119.
3 Recommended input fusing is a 10A 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 119.
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
EXB250-48S3V3-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
