Power Supply Specifications - Intergraph InterServe 80 SL System Reference Manual

Power Supply Specifications

The InterServe 80 SL uses a 250-watt manual-ranging supply. It switches between 90-132
VAC or 180-264 VAC, depending on the range setting. The input frequency is 47-63 Hz,
single phase. At full load, the power supply has a minimum efficiency of 65 percent.
The power supply contains no user- or field-serviceable parts. The power supply is enclosed
in a case that includes a fan to provide additional airflow through the system. Refer to
"Cooling Fan Specifications" later in this chapter for more information.
The following table details the DC output specifications for the power supply.

The following notes apply:
1. Power supply should meet or exceed these specifications. For the noted specifications,
the maximum values describe the smallest acceptable maximum load and the minimum
values describe the largest acceptable minimum load.
2. The maximum combined continuous load of the +5.0V and +3.3V outputs shall not
exceed 170 Watts.
