Alpha 400 Handbook
Valid voltage ranges for @ and @/@ for each module are as follows:
Module
Voltage Range
AA
@ = 4.5 – 7V
A
@ = 4.5 – 6V
AL
@ = 4.75 – 5.3V
BB
@ = 4.5 – 7V
B
@ = 4.5 – 6V
C, CC
@ = 5 – 16V
CL
@ = 4.6 – 5.6V
CM
@ = 5 – 7V
CH
@ = 11.4 – 13.5V
D, DD
@ = 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
EL
@ = 5 – 7V / 11 – 13V
EH
@ = 11 – 13V / 11 – 13V
F, FF
@ = 9 – 16V

Description
_MG
Provides a module good signal with indicates output voltage is within limits.
_PA, RJ
Forces paralleled modules to share load current. Additionally it also provides the module
good signal.
_PP, PJ
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, IJ
Provides an external signal which may be used to inhibit the output of the module.
_RP
Provides remote programming of the module output voltage.
RPA
Provides voltage programming of the module output voltage only.
RPB
Provides voltage programming of the module output voltage and has an output VA limiting
circuit.
RPC
Provides an output VA limiting circuit
RPD
Provides voltage programming of the module output voltage and has an output VA limiting
circuit.
Note:
The RPA option can only be used on modules with output voltages rated up to 32V.
The RP, RPB, RPC and RPD options 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.
