Notes
1 Latching OVP response time is 2 ms (typ.). OVP latch is reset by toggling
the control input, or by cycling the input voltage.
2 User must provide recommended fuses in order to comply with safety
approvals.
3 Meets both level A and level B conducted emissions only with external
components connected before the input pins to the converter.
4 Maximum temperature on hotspots not to exceed 110 ºC. See Application
Note 127 on Artesyn Technologies website www.artesyn.com.
5 See the longform datasheet for derating curves.
6 For stable operation connect an external output capacitor of at least
100 µF to each output. Recommended capacity AVX TPS series
(e.g. TPSD107*010#0100) or equivalents.
7 Active low remote ON/OFF, is available. Standard product is active high.
Designate with the suffix ‘-R’ e.g. EXB50-48D05-3V3-RJ.
8 Maximum total current from the module is 15 A for EXB50-48D05-3V3J and
17 A for EXB50-48D3V3-1V8J with airflow.
9 The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant.
TSE RoHS 5/6 (non Pb-free) compliant versions may be available on
special request, please contact your local sales representative for details.
10 NOTICE: Some models do not support all options. Please contact your
