Current Sharing | Xantrex Technology GPIB-M-XFR, GPIB-M-XHR instruction

Section 5. Current Sharing

Overview

CAUTION

Always exercise caution when using the current sharing feature. If a unit is set to Master or Slave, it will be locked out of local operation. Current sharing units will have their outputs disabled if one power supply enters shutdown.

The current sharing function allows power supplies to current share between units connected in parallel. Current sharing can use a maximum of 5 supplies. All power supplies must be the same model. Every unit must have a unique address. See “Configure for Multichannel Operation” on page 35.
