Setting Foldback Mode - Xantrex Watt Series Programmable DC Power Supply XG 850 Operating Manual

Setting Foldback Mode

between the operating modes. The power supply will turn off/disable the
output and lock in foldback mode after a specified delay if the power
supply transitions into CV mode or into CC mode, depending on the
foldback mode settings. This feature is particularly useful for protecting
