Latching OVP response time is 2ms (typ.). OVP latch is reset by toggling
the control input, or by cycling the input voltage.
User must provide recommended fuses in order to comply with safety
approvals.
Meets both level A and level B conducted emissions only with external
components connected before the input pins to the converter.
Maximum temperature on hotspots not to exceed 110ºC. See Application
Note 127 on Artesyn Technologies website www.artesyn.com.
See the long form data sheet for derating curves.
For stable operation connect an external output capacitor of at least 100µF
to each output. Recommended capacity AVX TPS series
(e.g. TPSD107*010#0100) or equivalents.
Active low remote ON/OFF, is available. Standard product is active high.
Designate with the suffix ‘-R’ e.g. EXB50-48D05-3V3-R.
Maximum total current from the module is 15A for EXB50-48D05-3V3 and
17A for EXB50-48D3V3-1V8 with airflow.
