4.13. LAST SETTING MEMORY
The power supply is equipped with Last Setting Memory, which stores power supply parameters at
each AC turn-off sequence.
STOREDPARAMETERS:
1. Output voltage setting
2. Output constant・current mode・limit
3. OVP level
4. UVL level
5. FOLD setting
6. Start-up mode (Safe or Auto-restart)
7. Remote/Local (If the last setting was Local Lockout, the supply will return to Remote mode)
8. Address setting
9. Baud rate
10. Locked /Unlocked front panel
(Items 7, 8, 9 are related to Remote digital control operation and explained in chapter 6)
4.14. 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.
5.14.1 Series connection for increased output voltage
In this mode, two units are connected so that their outputs are summed. Set the 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 start up
sequence or in case one of the units shuts down. Each diode should be rated to at least the power
supply rated output voltage and output current. Refer to Fig.5-1 and 5-2 for series operation with
local and remote sensing.
CAUTION
Do not connect power supplies from different manufacturers in series or in
parallel.
WARNING
When power supplies are connected in series, and the load or one of the output
terminals is grounded, no point may be at a greater potential of +/-60VDC
from ground for models up to 60VDC Rated Output and +/-600VDC from
ground for models >60VDC Rated Output. When using RS232/485 or IEEE,
refer to the OUTPUT TERMINALS GROUNDING warning, section 3.9.11.
