M850 MULTIFUNCTION METERS DESCRIPTION The new range of Hobut multifunction panel meters feature 96 x 96mm sizes complete with unique blue LED screen, which can be seen in direct sunlight. The range is easy to use, features user-programmable CT & VT ratios, and can be used on any single or 3 phase system with any input voltage without re-programming. APPLICATION The range is a cost effective replacement for traditional panel meters and is suitable for low, medium and high voltage control panels, gensets, building management systems, power management and more.
