Technical Architecture & Functional Positioning

The F650BABF2G0I is identical in protection and control capability to the HI-supply version (F650BABF1G0HIC) but is factory-configured for low-voltage 24–48 V DC station batteries commonly found in telecom sites, older substations, solar farms, and many industrial plants. The LO power supply module includes wider input filtering and higher inrush tolerance to operate reliably on battery-backed DC systems that may experience deep discharge or ripple.

This variant is the standard choice wherever 110–250 V DC is unavailable or where standardization on 48 V DC plant power is required.
