Current Sharing (6000 Watt only)

Overview

SCPI

Select whether the unit will operate as a master or slave unit:

SOURCE:COMBine:CSHare:MODE [MASTer SLAVe OFF]

To query the total output current of all current sharing units, use the SCPI command:

MEAS:CURR? SUM

The current share subregister (CSHare) will show whether the master or slave is operating.

STAT:OPER:CSH:COND?

See Table 4.14, “Current SHare Sub-Register,” on page 148 for a description of the bits in this register.

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.
