6.4.1. Setting the Supplies for Advanced Parallel
The front panel is used to set a power supply as an Advanced Parallel master or slave.
To set the master, it is required to know how many parallel slaves will be tied to its
output.
a) Depress and hold the FINE button for 3 seconds. The default setting, "H1", may
appear on the current display.
b) Rotate the current encoder to obtain the desired mode from the table below.
CURRENT Display
c) To lock in the new master or slave setting, wait a few seconds for the display to clear.
6.4.2. Master and Slave Units Default Operation
a) When a unit is programmed to Slave mode it enters the Remote mode with Local
Lockout. In this mode, the front panel controls are disabled.
b) The slave front panel display will only show "On" or a fault condition.
c) The Slave units parameters will automatically set the following:
 Output voltage to ~102% of rated output voltage
 Programmed Current to zero
 UVL to zero volts
 OVP to its maximum value
d) The Master and Slave modes are stored in the power supply EPROM when the AC
power is turned off. The system will return to the Master/Slave mode upon re-
application of AC power.
6.4.3. Current Display Accuracy
In the advanced parallel mode, the Master unit does not display actual total current of all
units in parallel. In this method, the CURRENT display accuracy is 2% +/- 1 count.
In cases that higher accuracy is required, it is recommended to use the basic parallel
operation mode and get the current measurements from each supply and add them to get
the total current.
H1 Single supply (default)
H2 Master supply with 1 Slave supply
H3 Master supply with 2 Slave supplies
H4
Master supply with 3 Slave supplies
S Slave supply
