when terminated in the load impedance specified.Ripple and noise are measured at the
connectors with a 0.1uF ceramic capacitor and A 47uF electrolytic capacitor to simulate
system loading. Ripple shall be measured under any condition of line voltage,output load,
line frequency, operation temperature.
2.3 Efficiency
Power supply efficiency minimum 70% at normal AC main voltage and full load .
F
3.0 PROTECTION
3.1 Over-power protection
The power supply will be shut down when output power over 150% of
rated DC output.
(The power supply will be self recovering when the fault condition is removed.)
3.2 Short circuit
The power supply shall shut down for shorting the+12VDC output.
(The power supply will be self recovering when the fault condition is removed.)
