6. Connection to the Load
Two-Wire Method
In parallel operation, power supplies can be connected for local or remote
sensing. Refer to
Fig. 6-7 and 6-8 for typical connections of parallel power
supplies. The figures show the connections for two (2) units, however the
same connection method applies for up to four (4) units.
With local sensing, it is important to minimize the wire length and
resistance. Also, the positive and negative wire resistance should be as
close as possible to each other to achieve current balance between power
supplies.
Single-Wire Method
In Parallel operation, power supplies can be connected for local or remote
sensing. Refer to
Fig. 6-9 and 6-10 for typical connections of parallel
power supplies. The figures show the connections for two (2) units,
however the same connection method applies for up to four (4) units.
With local sensing, it is important to minimize the wire length and
resistance. Also, the positive and negative wire resistance should be as
close as possible to each other to achieve current balance between power
supplies.
6.2.2. Advanced Parallel Operation (Two-Wire/Single-Wire Method)
In this method, multiple supplies can be configured to parallel operation as a single power
supply. The total load current and Output Voltage are displayed by the Master unit and
can be read back from the Master unit. The Slave units display only their operating
status (On, Off or Fault condition).
Refer to the following procedure to configure multiple supplies for Advanced Parallel
operation.
NOTE
When operating in the “ Advanced Parallel ” configuration using Single-Wire
control, the Output current delivered by each Power Supply may not be equal and is
considered typical operation.
In an “ Advanced Parallel ” system, the Output current measured by the Master unit
is only the Master unit’s Output current multiplied by two, three or four (depending
on the number of Slave units in the system).
The total parallel system Output current may be different, subject to the combined
output errors of the Slave units.
It is required to use the Shutoff Daisy-Chain with the “ Advanced Parallel ”
configuration.
