Integral Power Supply
Warning: The integral power supply in racks utilize high voltage
(120 or 240VAC). Unplug the unit before servicing.
The power supply for the series 8000 rack enclosures are integral to the chassis and mounted
on the back panel for better heat dissipation. All of the Series 8000 power supplies provide a
+/-15VDC+/-.5V linear regulated output for low noise operation. The available current is
500mA per side in the 1/2 and 3/4 rack configurations and 1A per side in full rack
configurations. Most measuring channels and function cards from Kaman typically draw less
than 70mA per side. When adding additional function cards or measuring channels to the unit
you should check on the actual current amount by referring to the specifications on each module
and adding up the total current draw from the power supply. For example, if you had 10
measuring channels you should allow for the supply to be able to handle 700mA (full rack
configuration). The MCD-8000 or other 1/8 DIN display modules are powered directly off the
AC input and therefore draw no current from the integral supplies. The power supply
specifications are summarized in table 1 below:
