About the
P120-250
Power Supply
The P120-250 is an AC input isolated power supply module for a Compact 984 CPU
installed in a DC environment. It is also suitable for use with the A120 I/O. A
conformal coated version, the P120-250C, is also available.
The P120-250(C) accepts input voltages from 90 to 264 VAC, and supplies 24 VDC
to the CPU at 2.0 A continuous current.
This supply is designed to be inserted in any available I/O slot in the backplane just
like the standard A120 I/O module, but connections are not made through the
backplane. Connections are made to the appropriate terminals located on the front
of the Power supply.
The following figure shows the front view of the P120-250(C) power supply.
