134 Using Agilent 668xA Series Power Supplies in Autoparallel
Example: 1 master unit, 2 slave units, Agilent Models 6680A (5V, 875A)
Iout = Im ( 3.0508 ) - 44.4A
The master current limit must be set above 44.4A /3.0508 = 14.55A to obtain any output current. For a no-load condition:
Master current =14.55A
Each slave current = -14.55A /2 = -7.28A
Iout = 0A
Note 2 All Agilent 668xAand 669xA power supplies have an output current programmed at power-on. The
default current value programmed at power-on can be found in Table 3-1 of the Programming Guide (p/n
5964-8269). See *RST and *SAV in the Programming Guide to change the power-on current value.
Note 3 A current programmed via the rear panel +Ip or -Ip inputs will be summed with the current programmed
via the front panel keypad or over the GPIB. When programming slave supplies via the rear panel +Ip or
-Ip
inputs, all slave current programming values must be zero (0 ).
