Alpha 400 Handbook
Valid voltage ranges for @ and @/@ for each module are as follows:
Module Voltage Range
A @ = 4.5 – 5.5V
AA @ = 4.5 – 6.5V
BB @ = 4.5 – 6.5V
B @ = 4.5 – 5.5V
C @ = 5 – 16V
D @ = 18 – 29V
E @/@ = 5 – 16V / 5 – 16V
EB @/@ = 4.5 – 5.5V / 4.5 – 5.5V
EQ @/@ = 4.5 – 5.5V / 2.7 – 3.9V
F @ = 9 – 16V
G @ = 17.5 – 29V
H @/@ = 18 – 32V / 18 – 32V
J @ = 30 – 48V
Secondary Options:
Option Description
_PA Forces paralleled modules to share load current. Additionally it also provides the module
good signal.
_PP Provides either of the following functions:
a) Reduces module current limit and caters for paralleled modules with busbar linking. For
use with modules providing a max output of up to 16V only; or
b) Identical to _PA except that the module is paralleled at the output of the module with
busbar linking.
_IN Provides an external signal which may be used to inhibit the output of the module.
_RP Provides remote programming of the module output voltage.
Note:
The RP option can only be used on modules with output voltages rated up to 16V.
Not for use with a module voltage range of 18-29V or twin output modules.

Adjustment and Derating:
The Alpha 400 series is designed to provide a max output power of 400W at nominal output voltages. The following
procedure must be used to ensure the PSU is operated within its ratings:
a) Calculate user power for each module (volts x amps).
b) Add all the individual module powers together. The total power must not exceed the power rating of the
C converter 400W.
