- 9W Indian high power factor (PF) (based on YT2302EHS7) emergency (based on YT7207AS10) lighting solution. - It supports operation within an ultra-wide input voltage range (90 - 440 Vac). In the high-voltage section (> 350 Vac) and the low-voltage section (< 150 Vac) of the grid voltage, the output current is reduced to improve system reliability. - Strong surge resistance: The surge capability is greater than 4 kV. - High power factor: > 0.95 @ 230 Vac input (Connect battery). - Battery voltage overcharge protection: > 4.24 Vdc. - Battery voltage overdischarge protection: > 2.7 Vdc. - Intelligent grid impedance detection algorithm to stably start and stop the emergency state. - It supports the mixed connection of the L and N phases of the grid. - Programmable charging current: Supports 500 mA fast charging. - Programmable discharge duration: Supports ultra-long time (> 8 hours) emergency lighting.

Due to the unstable power supply in countries and regions such as India and Bangladesh, especially the sharp increase in residential electricity consumption brought about by the high-temperature season from May to August every year, most areas in India will suffer from severe power shortages. In extreme cases, some residents can only get 2 to 3 hours of unstable power supply every day. Therefore, emergency lighting has emerged as the times require. In particular, functions such as fast charging (fully charging the battery within 5 hours or even less), slow discharging (discharging for 6 hours or even the advertised 24 hours), and charging while the light is off (that is, the function that enables the backup battery to be charged even when the main lighting is not turned on) have become the标志性 functions of emergency lighting.
