Power Requirements, Risk of damage to the board | Emerson PMPPC7448

Setup: PmPPC7448 Setup

Caution: Do not install the board in a rack or remove the board from a rack while power is applied, at

!risk of damage to the board.

Power Requirements

Be sure your power supply is sufficient for the PmPPC7448 circuit board. Standard power is

3.3volts, however a dual power supply option is available. Table 2-2lists the board’s specific power requirements.

Table 2-2:Power Requirements

		Current
Voltage:	Range:	(typical):	Watt Requirements/Configuration:
+3.3 V	+/- 5%	5.1 amps	1 GHz MPC7448 and 1 GB DDR SDRAM
			configuration typically requires 17 watts

Specific PmPPC7448 configurations may draw over 20 watts of power. The configurations with a faster core CPU frequency and increased DDR memory draw more power and gener- ate more heat. When monitoring the ambient air temperature increase across the module (from the inlet side of the PmPPC7448 to the outlet), the temperature can rise approxi- mately 4-7° C at high airflow (300 lfm) to 5-12° C at low airflow (100 lfm). The system designer should consider the cumulative effects of installing multiple PMC modules on a single carrier and ensure adequate airflow.

Environmental Considerations

As with any printed circuit board, be sure that air flow to the board is adequate. Chassis constraints and other factors greatly affect the air flow rate. The environmental require- ments are as follows:

Table 2-3:Environmental Requirements

Environment:	Range:	Relative Humidity:
Operating Temperature	0° to +55° Centigrade, ambient	Not to exceed 85%
	(at board)	(non-condensing)

Storage Temperature	—40° to 85° Centigrade	Not to exceed 95%
		(non-condensing)

Altitude	0 to 4,000 meters above sea level	n/a

Air Flow1	100 linear feet/minute @ 45° C ambient	n/a
	200 linear feet/minute @ 55° C ambient

1.Airflow is required at the processor to maintain junction temperature less than 95° C at specified ambient temperature.
