Current Share Boards – Optional Feature (Cont.)
Requirements:
1.
For proper operation, the power supplies being paralleled should be enabled at the same time.
2.
–OUT conductors must be of equal length and wire gauge. Separate –OUT conductors must be
used from each supply to the load or the use of a "Y" connection to a common point must be used
as shown in Figure 1. Each leg of the "Y" must have a minimum of a few millivolts of drop in order
for proper operation. 50 – 100mV of drop will provide from 5 to 1% accuracy.
3.
–V1 and –V2 for all box-to-box circuits must be connected directly at the negative output power
studs or terminals to achieve accurate current sharing.
4.
D* can be added if redundancy is needed. If redundancy is not required, D* can be replaced with
direct wire connections.
5.
When using D*, the Power input should be connected on the cathode side of the paralleling diodes
as shown previously.
6.
Terminate sense leads either locally or remotely as shown in Figure 12.
7.
For paralleling more than two supplies consult factory for assistance.
