Alpha 600 Handbook
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.

Adjustment and Derating.
The Alpha 600 series is designed to provide a maximum output power of 600W 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
converter, 600W.
c) Calculate secondary transformer turns x amps or each module see outputs table for transformer
secondary turns.
d) Add all the module turns x amps together and this must not exceed 120AT.
e) If necessary reduce the loading until the conditions are met. i.e. power and ampere-turns maxima.
