HD-BUPS

Dedicated lightning protection box for compotator UPS This product is applicable to lightning and electric surge protection of lightning protection area LPZ1 or LPZ2 to LPZ3 area (Grade D or Grade Ⅲ), as well as single-phase and three-phase supply circuit. Vital components of this product adopt the advanced high capacity surge absorber member MOV, and have passed the burn-in screen with even quality and quick response time. Product connection in series is superior to that of parallel connection in protective property. It has even lower limit to output voltage and can protect the equipment effectively. With LC filter circuit and current limiting device, its protection grade can reach IP30. This kind of product is of complete function, convenient installation, and the function of operating light as well as fault detection.

Section of minimum installed conductor 6mm2 Multi-folded wire Sheathing material Metal Spraying Mode of connection Connection in series Protection mode Overall protection Installation Method: Ground the null line repeatedly when long-distance overhead incoming feeder is connected to the building. L and N are terminal for power incoming feeder; L ' and N ' are terminal for lead-in equipment, which is installed at the leading end of DPS incoming feeder. It's suggested power earthing (PE) be well connected with lightning protection ground lead (suggested earth resistance ≤4Ω).Suggested specification of the lead wire: no less than 10m2, short and straight.
