The extensive range of output modules and options make it possible to achieve many combinations of Volts and Amps. To achieve the opti-
mum 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 Cooling and
Leakage Current from the following table:-
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
Ensure that the total width of all selected modules is within the slots for the chosen converter. For example:-
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
