Extending the Voltage Range and Current Range

Extending the Voltage Range and Current Range
The power supply may be able to provide voltages and
currents greater than its rated maximum outputs if the
power- line voltage is at or above its nominal value.
Operation can be extended up to 3% over the rated output
without damage to the power supply, but performance can
not be guaranteed to meet specifications in this region. If
the power- line voltage is maintained in the upper end of the
input voltage range, the power supply will probably operate
within its specifications. The power supply is more likely to
stay within specifications if only one of the voltage or
current outputs is exceeded.
Series connections
Series operation of two or more power supplies can be
accomplished up to the output isolation rating of any one
supply to obtain a higher voltage than that available from a
single supply. Series connected power supplies can be
operated with one load across both power supplies or with a
separate load for each power supply. The power supply has
a reverse polarity diode connected across the output
terminals so that if operated in series with other power
supplies, damage will not occur if the load is short- circuited
or if one power supply is turned on separately from its
series partners.
When series connection is used, the output voltage is the
sum of the voltages of the individual power supplies. The
current is the current of any one power supply. Each of the
individual power supplies must be adjusted in order to
obtain the total output voltage.
