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 cannot 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
You can connect up to four E36100 Series power supplies up to the output isolation rating of any one
supply to obtain a higher voltage than a single power supply can produce. 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 the 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.
Parallel connections
You can connect up to four E36100 Series power supplies in parallel to obtain a total output current
greater than a single power supply can produce. The total output current is the sum of the output
currents of the individual power supplies. The output of each power supply can be set separately. The
output voltage controls of one power supply should be set to the desired output voltage; the other
power supply should be set for a slightly higher output voltage. The supply with the higher output
voltage setting will deliver its constant current output, and drop its output voltage until it equals the
output of the other supply, and the other supply will remain in the constant voltage operation and only
deliver that fraction of its rated output current which is necessary to fulfill the total load demand.
