KDC Series II DC Power Supplies
5.2.2
Auto-Series Operation
In the auto-series mode of operation, a master/auxiliary configuration is established as shown in
Figure 5-10.
Note:
For this mode of operation, both power supply controllers are hardware
configured for stand-alone operation. Thus, the auxiliary unit must not be
configured for the
–AUX parallel mode. The –AUX configuration settings
outlined in section 5.2.1.3 only apply to the auto parallel mode.

Vsum = Vmstr + Vaux (Note: Maximum allowed is 600 VDC).
Rx = 2 * (Vmstr - 10) KOhm
For units with range > 300Vdc, use 2 RN60 Resistors
(0.5 Rx + 0. 5 Rx ) in series.

Note:
The cable used to connect to the analog I/O connector J22 on the Auxiliary
unit must have a ferrite bead with 5 turns of both wires through it to reduce
RF noise pickup. Suitable bead is C/I P/N 211159, Amidon # FT87A-F.
