Setup

Current

Sharing

Network

To set up multiple supplies for current share operation, follow these steps:

1. Configure each supply with a unique multichannel address. (See “Multichannel

Operation (6000 Watt only)” on page 113.)
Configure one supply to operate as the master. Configure others to operate as
slaves.

2. Power down the units. Connect the CAN ports of all paralleled units as you

would for multichannel operation

3. Make load connections. It is recommended to keep load cables the same length

if possible. See Figure 5.1.

4. Power up the master, then all slaves.
5. Set the voltage on the master, then enable the output.
