This is the "small brother" of the monster base A-100PMB. It is very similar to the A-100PMB but has only half the width (2 x 84 HP for installation of modules). The suitcase versions A-100P6 or A-100P9 can be positioned on top of the A-100PB because the width of the A-100PB is a bit more than the width of A-100P6/P9 and the footprint of the A-100PB is adapted to the depth of A-100P6/P9. A-100PB is equipped with one power supply (1200mA) and two bus boards. The bus boards are located in the rear area (even those for the modules that are mounted in the front row). This was necessary to take advantage of the full height of the front area for installation of A-100 modules.

Measures:
outside: approx. 510 (width) x 210 (height) x 420 (depth) mm
inside: 2 x 84 HP x 3 U
usable depth for A-100 modules front row: approx. 70 mm
usable depth for A-100 modules rear row: approx. 100 mm

Weight (without modules): about 9 kg

Electrical specifications:
mains voltage: 115V~
output voltages/current: +12V/2000mA, -12V/1200mA, +5V/4000mA

The new power supply is named A-100PSU3 and has available 2000mA@+12V, 1200mA@-12V and additional +5V with 4000mA. +5V are no longer required for A-100 modules but there are many modules from other manufacturers that require +5V.
