Bodine’s patented Auto-Dim is a feature unique to our ELI series inverters which allows for a lighting load to be much greater than the inverter’s ratings when in the normal AC mode. Auto-Dim allows for your fixtures to be on, off, switched, or dimmed, all without affecting emergency operation.
When normal power is present, the inverter simply passes AC power to the connected luminaires. When power fails, the inverter’s internal circuitry draws power from the battery to supply 120 or 277 VAC. If this power draw exceeds the inverter’s output ratings, lesser inverters may not reach their rated runtime or, worse still, not function at all. A Bodine ELI series inverter with Auto-Dim monitors its output voltage and current to detect the power draw of the connected luminaires and controls the 0-10V lines to optimize their power draw.
