"The reliability and availability of these Industrial Computers have
been improved with the availability of an optional 180-watt Battery
backup feature. This feature allows continuous operation through brief
main-power interruptions (nominal default of 10 seconds), providing
increased availability and minimizing down time."

The PSU itself [sans battery] is P/N 33F5202, FRU 57F2728, made by
Plessey in 46-91

Input 95-120V 3.6A 50-60 Hz
Input 200-240V 1.9A 50-60 Hz

Code 3225-18-001 [?]

Output DC: +5V 25.6 A / +12V 3.3A / -12V 1A

Battery Charger: 26V 40mA
Max Output Power 180 W

My SWAG is the battery did not come with the PSU, but was ordered
separately. There is an external two or four pin DC power plug that
hooks over a metal loop on the outside of the PSU. Not sure why.

My DIMM memories of the PSU in the 7162 I took apart was the battery
compartment at the front, below the power switch, had the actual plug
for the battery.

What the external plug is for is unknown, possumbly a case fan.

The industrial computers didn't get the love, and were kept in the dark.

I did winkle out the existence of the 7533, a 8530-286 planared
Industrial Computer.

Quoting myself,

"This PSU has an external, two pin Molex connector that provides power
to the case fan. There is a 9.25" (W) x 1.75" (H) hinged cover on the
lower outer side of the PSU. It is fastened at the front by a single
captive standard screw. The cover pivots open on the rear hinges,
revealing a three pin Molex power connector, like a female drive power
connector. The battery cavity is 1.875" deep."
