tions. P rotection circuits in the power supply will not cause the AC fuse to blow unless a compo-
nent in the power supply has failed. This includes DC output load short conditions. The DC load
short circuit protection circuits will shut down or limit power supply without causing the AC line
fuse to blow.
5.5.3.3 Power Factor Correction
The power supply incorporates a power factor correction circuit.
The power supply is tested as described in EN 61000-3-2: Electromagnetic Compatibility (EMC)
Part 3: Limits- Section 2: Limits for Harmonic Current Emissions, and must meet the harmonic
current emissions limits specified for ITE equipment.
The power supply is tested as described in JEIDA MITI Guideline for Suppression of High Har-
monics in Appliances and General-Use Equipment and must meet the harmonic current emis-
sions limits specified for ITE equipment.
5.5.4 DC Output Specification
The power supply DC output specification is met by a single supply, by two supplies, or by three
supplies operating with their outputs directly paralleled. When operated in parallel, the supplies
share the total load currents equally within the limits specified, and meet all performance require-
ments of individual supplies. Failure of a supply in a paralleled group, or removal of an opera-
tional or failed supply from a paralleled group will not cause DC output transients in excess of the
limits specified. Adding an operational or failed supply to a paralleled group will not cause DC
output transients in excess of the limits specified.
5.5.4.1 DC Outputs Rating
The steady state and peak DC output load currents are in the ranges shown in Table 5-4: Load
Range.
