Appendix B Power Supply Specifications 109
B.4 Environmental Specifications
Operating temperature: 0 ~ 50° C, rated load
Storage temperature: -40 ~ 85° C
B.5 Features
Efficiency: Higher than 70% (typical) while measuring at nominal line
and rated load.
Hold up time: Longer than 16 ms at 115 V
AC
input and rated load, which
is measured from the end of the last charging pulse to when the main
output drops down to 95% output voltage.
Protection: If the power supply fails to control itself, the built-in
excess voltage protection circuit will shut down the outputs to avoid
damaging external circuits. The trip point of the crowbar circuit is
around 5.7 V to 7.0 V for output voltage. The power supply will go into
latch-off mode under short circuit or overload conditions. Recovery
from these adverse conditions should be set as cycle AC, input OFF
and ON.
Safety ground leakage current: It should be less than 100 µA at 244
V
AC
input.
