2.1.2 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.
2.1.3 Withstand Voltage
The power supply is capable of withstanding a maximum 1500 VDC
potential between the input and ground for a period of 1 second.
2.1.4 Catastrophic Failure Protection
If a component failure occurs, the power supply will not exhibit any of
the following:
1)
Flame
2) Excessive smoke
3) Charred PCB
4) Fused PCB conductor
5) Startling noise
6) Emission of molten material
2.2 DC Output
2.2.1 DC Voltage Regulation
The DC output voltages are remain within the regulation ranges shown in Table
2 when measured at the load end of the output connectors under all line, Load,
and environmental conditions.
Table 2. DC Input Line Requirements
Output Range Min. Nom.(1) Max. Unit
+12V1DC ± 5% +11.40 +12.00 +12.60 Volts
+12V2DC ± 5% +11.40 +12.00 +12.60 Volts
+5VDC ± 5% +4.75 +5.00 +5.25 Volts
