HD-BUPS

Lightning protection box for UPS computer This product is suitable for lightning and surge protection of single-phase, three-phase power lines of lightning protection zone LPZ1 or LPZ2 to LPZ3 (grade D or III). Vital components of this product adopt the advanced high capacity surge absorber member MOV, and have passed the burn-in screen with stable quality and quick response time. Product in series is superior to that of parallel connection in protective property. It has lower output voltage limit 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 series connection Protection mode Full-protection Installation method： Ground the null line repeatedly when Long-distance overhead incoming lines enter buildings. Plug the power phase line (L) and null line (N）into corresponding connector of the electric surge protector and make sure it's firm and reliable. Connect the ground terminal of arrester with the ground lead of lightning protection well (recommended earth resistance ≤4Ω). Suggested specification of the lead wire: no less than 6mm2, short and straight.
