HARACTERISTICS
D IMENSIONS
4.2 inch wide, 6.75 inch high, and 15 inch deep.
W EIGHT
375W: 8.2 pound maximum.
750W: 12.9 pound maximum.
M OUNTING P ROVISIONS
Captive retaining screw affixed to the front panel mating with the mainframe.
No module extraction provisions, such as levers, are provided; modules are
extracted using front-panel mounted handles
C OOLING P ROVISIONS
Operation at maximum limits of output power, ambient temperature, and
altitude requires 110CFM of airflow through module. Integral fans have variable
fan speed control that is dependent on internal module temperatures.
A COUSTIC N OISE
The speed of the integral fans is linearly variable, as a function of internal
heatsink temperature rise, to minimize acoustic noise and extend the fan life.
The speed varies from nominally 50% of full-speed to full-speed as the
heatsink temperature varies with ambient temperature and power dissipation
resulting from the input load.
F RONT P ANEL C ONNECTOR M ATING L IFE
500 mating cycles, maximum.
