2022 New Design 480V Input Emergency LED Driver ————Helpower Technology Input 480VLED Emergency Drive, independently developed by Helpower Technology, it’s made of compact metal shell with wide input voltage 277~480Vac and output voltage 280~550Vdc, external installation application, connected between the Utility Power and LED lamps, no need to change the original structure of the Lights When mounting.It can be mix-wise used with LED drivers in the range of AC100-550V to reach Lighting conditions. The Li-ion battery is used as the energy storage power source. When the ambient temperature is 0-50 ℃, it can meet the charging and discharging requirements of the battery, and the PF value of the charging state is as high as 0.99. During emergency working state, the 480EM Driver will provide constant power output and not less than 90mins. The Driver has output short-circuit protection, open-circuit protection, overload protection, overcharge protection, over-discharge protection ect, which improve the life of Lights and LED Emergency Driver effectively, and make it safer to use. Features: Multiple Protection Functions: short-circuit protection, overload protection, open circuit protection, overcharge protection, overdischarge protection. The minimum emergency time is 90 mins, which meets the discharge time requirements of UL emergency lamps. Surge level: L-N 3KV, L&N-PE 3KV Ringing wave: L-N 2.5KV, L&N-PE 2.5KV Certifications: UL/cUL 924 Listed certification PF value up to 0.99 when charging Constant power output Warranty: 5 years Model: Model VIN VOUT EM Power Discharge Size EMA-20AAAWW-YY 277~480Vac 280~550Vdc 20 w 1.5h 313*59*46 EMA-40AAAWW-YY 277~480Vac 280~550Vdc 40 w 1.5h 313*59*46 Wiring: 1.
