*For Active PFC Vin=100~240Vac full-range, PF=0.95min.
*For Passive PFC Vin=115/230Vac by-switch, PF=0.85 typ.
*For Active PFC Vin=100~240Vac full-range, PF=0.95min.
*For Passive PFC Vin=115/230Vac by-switch, PF=0.85 typ.
3.1.2 AC over current Protection:
The power supply shall incorporate primary fusing for input overcurrent protection. Fuses
should be slow-blow type or equivalent to prevent nuisance trips.
should be slow-blow type or equivalent to prevent nuisance trips.
3.1.3 Inrush Current Limiting:
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.

3.1.4 Input under voltage:
The power supply shall contain protection circuitry such that the application of an input
voltage below the minimum specified in Section 3.1, Table 1, shall not cause damage to
the power supply.

the power supply.
3.1.5 Electrical fast transient/burst:
No unsafe operation is allowed under any condition. No user-noticeable performance
degradation up to +- 1 kV Mains, +- 500V Signal Cable, is allowed. Automatic or manual
recovery is allowed for other conditions.
