Adjustment and Derating.
The Vega 900 series is designed to provide a max output power of 900W at nominal output volt-
ages. 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 value
given.
c Calculate secondary transformer turns x amps for each module. See the outputs table
for transformer secondary turns.
d Add all the module turns x amps together and this must not exceed the ampere turns.
e If necessary reduce the loading until the conditions are met, ie. power and ampere-turns
maxima.

Note 1:The PSU main transformer has three regions for module secondaries seperated by two
primary windings. Starting nearest slot 1, region A, primary winding, region B, primary winding,
region C. The total ampere turns (AT) in any two adjacent regions is limited to that in the table
above column, " Max AT in adjacent regions (note 1)".See mains transformer regions table
below for modules allowed in each region. The table uses module widths with a twin output
module being single width

Customer Air Cooling (option C):
The following method must be used for determining the safe operation of PSUs when C option
165 - 240VAC (Customer Air) is fitted, ie fan not fitted to PSU.
150 - 264VAC
For PSUs cooled by customer supplied airflow the components listed in the following table must
47- 63Hz
not exceed the temperatures given. Additionally ratings specified for units with an internal fan
9 A AC
must still be complied with, eg mains input voltage range, maximum output power, ampere turns,
<40 AMPS
module voltage / current ratings and maximum ambient temperature. To determine the component
temperatures the heating tests must be conducted in accordance with the requirements of
IEC/EN/CSA60950-1:2001 Clause 4.5. Consideration should also be give to the requirements of
other safety standards.
Test requirements include: PSU to be fitted in its end-use equipment and operated under the
most adverse conditions permitted in the end-use equipment handbook/specification and which
will result in the highest temperatures in the PSU. To determine the most adverse conditions
consideration should be given to the end use equipment maximum operating ambient, the PSU
loading and input voltage, ventilation, end use equipment orientation, the position of doors & cov-
ers, etc. Temperatures should be monitored using type K fine wire thermocouples (secured with
cyanoacrylate adhesive, or similar) placed on the hottest part of the component (out of any direct
airflow) and the equipment should be run until all temperatures have stabilised.
