The Decision-Maker® 3000 cabinet meets NFPA 110, Level 1 standards when equipped with the necessary accessories and installed according to NFPA standards. The Decision-Maker® 3000 cabinet uses patented software to manage sophisticated functions, such as voltage regulation and thermal protection of the alternator, which normally requires additional hardware. Additional features include: - A digital display with push buttons/rotary selector for easy access to local data. - Measurements in metric or imperial units. - A scrolling display to show critical data at a glance. - A digital display for power measurements (Kw and Kva). - An integrated hybrid voltage regulator providing regulation of ±0.5%. - An incorporated thermal alternator for overload protection.
