2.2. INRUSH CURRENT
Maximum inrush current from power-on (with power on at any point on the AC sine) and including, but not limited to,
three line cycles, shall be limited to a level below the surge rating of the input line cord, AC switch if present, bridge
rectifier, fuse, and EMI filter components. Repetitive ON/OFF cycling of the AC input voltage should not damage the
power supply or cause the input fuse to blow.

2.4. AC-DC power supplies shall not perform at less than:
(AC input=230V)
1. Power factor 0.8 at 20% of rated output.
2. Power factor 0.9 at 50% of rated output.
3. Power factor 0.95 at 100% of rated output.
3. EFFICIENCY
Under the load conditions defined in table 1. And table 2.
The loading condition for testing efficiency shown in Table 1 represents a fully loaded system. A ~ 50% (typical)
loaded system and a ~ 20% (light) loaded system.
