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.
Input Parameters
Output Parameters
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.
Customer Air Cooling (option C):
The following method must be used for determining the safe operation of PSUs when C option
(Customer Air) is fitted, ie fan not fitted to PSU.
For PSUs cooled by customer supplied airflow the components listed in the following table must
not exceed the temperatures given. Additionally ratings specified for units with an internal fan
must still be complied with, eg mains input voltage range, maximum output power, ampere turns,
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.
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.

4 SELV and Outputs connected in Series
Outputs are SELV except as described below
- Non-earthed outputs that have secondaries with 2 or more turns are non-SELV as
a single fault in the secondary may make them exceed the SELV limit between
output and earth.
- Non-earthed ouputs that are connected in series are non-SELV unless all the
seriesed outputs use 1 turn secondaries and there are no more than 3 outputs
connected in series.
- Outputs connected in series are non-SELV if the total output voltage + 20% of the
max, rated output voltage of the output with the highest rated voltage exceeds
60dc (the 20% addition allows for a single fault in any one individual channel)
- The total voltage of a seriesed output must not exceed 160V
- If any ouput or seriesed output is non-SELV then all the outputs in the PSU must
be considered non-SELV
Note
- Non-SELV outputs must be gaurded or a deflector fitted during installation to
avoid a service
engineer making inadvertent contact with the output terminals, or dropping a tool
onto them.
- All outputs operational spacings to earth, and due consideration must be given to
this in the end product design.

6 Actual voltage and current output of an X module is dependent, and limited by, the
ratings of the modules from which it is fed. The ratings given above for the X module
are additional rating limitations imposed by the X module itself.

following power:

8. Adjusting output voltage beyond the stated range may cause overvoltage protection
(OVP) to operate, whereby all outputs will turn off. To reset OVP, turn back output
voltage adjustment and remove the mains supply for 30 seconds and then will switch
back on.
Approval Limitations: Use in North America (AC units only)
When this product is used on 180VAC-250VAC mains with no neutral, connect the two live wires
to L(live) and N (neutral) terminals on the input connector. In this instance double pole fusing is
required.
High Voltage Warning
Dangerous voltages present within the power supply. Do not remove covers.
External Hot Surfaces
Section 6 of the Health and Safety at Work Act requires that manufacturers have an obligation to
protect service engineers as well as users. In order to comply with this, a label must be fitted to
these products which is clearly visible to service personnel accessing the overall equipment, and
which legibly warns that surfaces of these products may be hot and must not be touched when the
products are in operation.
Safety Earthing Screw
On products with an enclosure, special safety earthing screws are used which connect the cover to
the chassis. They must not be removed.
Safety Class of Protection
These products are designed for the following parameters : Material Group IIIb, Pollution Degree 2,
Overvoltage Category II, Class 1 (earthed), Indoor use as part of an overall equipment such that
the product is accessible to service engineers only.
Energy Hazards
Certain modules are capable of providing hazardous energy (240VA) according to output voltage
setting. Final equipment manufacturers must provide protection to service personnel against
inadvertent contact with these module output terminals. If set such that hazardous energy can
occur then the module terminals or connections must not be user accessible.
Servicing
These products are not customer serviceable. Repairs may only be carried out by Lambda UK or
their authorised agents. These products are not authorised for use as critical components in nuclear
control systems, life support systems or equipment for use in hazardous environments without the
express written approval of the Managing Director of Coutant Lambda Ltd.
Important safety instructions
The Vega family of component power supplies is designed for use within other equipment or
enclosures which restrict access to authorised competent personnel only. For safe installation and
operation of this product, carefully follow the instructions listed below.
i) The unit covers/chassis are designed to protect only skilled personnel from hazards and must
not be made user accessible.
ii) These products are Class 1 and must therefore be reliably earthed and professionally installed
in accordance with the prevailing electrical wiring regulations and the safety standards covered
herein.
iii) These products are IPX0, and therefore chemicals/solvents, cleaning agents and other liquids
must not be used.
iv) If the earth terminal of the Vega PSU is connected to the main incoming earth conductor of
the end equipment, the installer must cover the Vega earth symbol with a label bearing the earth
symbol of IEC60417-5019.

Special instructions for applications covered by IEC/EN/UL/CSA61010-1.
Whilst all individual module single outputs are classed as SELV outputs in accordance with IEC/EN/
UL/CSAEN60950-1 (<60Vdc or 42.4V peak) serried combinations of these modules may exceed
these values and become hazardous output voltages. For IEC/EN/UL/CSA61010-1 the equivalent
limits are 70Vdc, 33Vrms or 46.7V peak.
Under single fault conditions these limits are increased for IEC/EN/UL.CSA61010-1 and UL3101-1
to 140Vdc, 55Vrms or 78V peak. Provided these levels are not exceeded, the outputs are not
considered hazardous for IEC/EN/UL/CSA61010-1
