4.6 Saving the Power Supply’s Current State
The current state of the power supply is saved after 2 seconds from the last
adjustment or after the “SAVE” command is received through the RS232 interface.
4.7 Connecting Two Power Supplies in Series
Two power supplies may be connected in series to provide a variable 0-60 volt
output. In this configuration, the two power supplies can supply up to 60V-1A. See
When connected in series, the voltage controls of each power supply exercise control
over a 0-30 volt range. Add the LED display readings together or connect an external
voltmeter across the load to determine the total output voltage.
Load current may be monitored from either supply; the readings will be identical
since they are connected in series. Also, since the supplies are connected in series, it
is only necessary to set the current limit on one of the supplies; the other may be set
for maximum.
