The H7848 Power Supply is used on the following computers resp. options:

Model H7848-AA is for nominal 115 V input and model H7848-AB is for nominal 230 V input.

The power supply assembly includes an ac power connector, an ac power switch, and a variable-speed cooling fan.

Output Power Ratings / Noise
Voltage (V) Current (A) Noise (mV)
Nominal Minimum Maximum Minimum Maximum Maximum
+5.10 +4.85 +5.35 3.00 10.00̣̣̣ 50
+12.10 +11.50 12.70 0.50 4.00 70
-12.00 -11.40 -12.60 0.00 0.25 120
-9.00 -8.55 -9.45 0.00 0.20 50
  • If the + 12.1 Vdc is limited to 3.0 Amps maximum, the +5.1 Vdc can supply up to 12.0 Amps.
  • If the + 12.1 Vdc is limited to 2.0 Amps maximum, the +5.1 Vdc can supply up to 13.0 Amps.

For options that to not provide the minimum loads, there is the 54-17163 Loads Board:

  • 5V, 3A
  • 12V, 1A

The board can be jumpered (using 0 Ohm resistors) to either loads or both.
