Alpha Configuring Guide
The extensive range of output modules and options make it possible to achieve many combinations of Volts and Amps. To achieve
the optimum configuration, please contact our sales office. However you can also create your own configuration from this datasheet
by using the guide below.
Configuring from Datasheet
1 Calculate total output power to determine Alpha 400W, 600W, 1000W or 1500W and select converter, then select required

Notes:

b) Contact sales office for details
Ensure that the total width of all selected modules is within the slots for the chosen converter. For example:-
2 Select Output Modules and Options from the Output Voltages tables.
Example - if you require 5.2V / 18A with output inhibit : -
a) select B as closest match for voltage and current and prefix with voltage (e.g.
5.2B)
b) add suffix for option (if required)
‘_PA’ for parallel/current share (for N+1 redundant applications)
‘_PP’ for parallel (increase current from one PSU)
‘_IN’ for inhibit
‘_RP’ for remote programming
‘_MF’ (only applicable on 1st module) for global inhibit, ac fail and 5V/50mA standby supply
c) repeat for other outputs
CA600LL 5A 12/12E 24D
which represents a four output 600W Alpha with Forward air, 240µA Earth Leakage, with:-
Output 1 = 5V / 60A with remote sense
Output 2 = 12V / 8A
Output 3 = 12V / 8A
Output 4 = 24V / 8A with remote sense
