6. SERIES AND PARALLEL OPERATION
Users may connect the outputs of Genesys™ Power Supplies together to produce:
▬
Voltages greater than any one supply rating (series connection).
▬
Plus and minus polarity (series connection).
▬
More current than any one supply rating (parallel connection).
In addition to connecting the outputs together, Remote Analog control connections are
used to ensure the supplies are properly sharing the total voltage or current. Remote
Digital programming through the RS-232/RS-485, LAN, IEMD or USB is allowed for all
power supplies.
NOTE
Consult your local TDK-Lambda Sales/Technical Support representative to
discuss your Series or Parallel application in detail.
NOTE
When a Power Supply is set to Remote Analog control then the
corresponding voltage or current encoder (and their PREView settings) will
not be effective.
Although the front panel seems like it can be used to adjust the Output
settings, it is the Remote Analog control lines that actually set the
programming limits.
6.1. Series Operation
Power supplies of the SAME MODEL can be connected in series to obtain increased
Output voltage. Split connection of the power supplies gives positive and negative Output
voltage.
CAUTION
Do not connect power supplies from different manufacturers in
series or in parallel.
Use only the same models for series or parallel connection.
6.1.1. Series Connection for Increased Output Voltage
In this mode, two units are connected so that their Output voltages are summed
(Series Operation). Set the Output current limit of each Power Supply to the
maximum that the load can handle without damage. It is recommended that diodes
be connected in parallel with each unit Output to prevent reverse voltage during the
startup sequence or in case one unit shuts down. Each diode should be rated for at
least the Power Supply rated Output voltage and Output current. Refer to Fig.6-1 and
6-2 for Series Operation with Local and Remote sensing.
