The high-performance current-mode PWM controller is specifically designed for cost-effective AC/DC conversion, providing up to 8W/DC24V continuous output power within a wide voltage range of AC110V-250V from the mains. The peak output power can reach 15W output, with current limiting for lithium battery charging.

It uses lithium polymer batteries, assembled into six series (2AH). During emergency lighting discharge, under rated power conditions, the time can reach over 4 hours. The cycle life of charging and discharging exceeds 500 times, ensuring a long service life.

A dedicated lithium battery protection chip ensures high-precision detection of each battery cell (over-discharge protection voltage: 2.7V±25mV (25℃), over-discharge release threshold: 3.0V±25mV (25℃), over-charge protection voltage: 4.20V±25mV (25℃), over-charge release threshold: 4.05±25mV (25℃)).

The panel switch in the 'I' position indicates standby charging status when mains power is available; when mains power is absent, it automatically switches to output DC24V, with battery charging voltage at 25V.

Protection features include overload, short circuit, high and low voltage battery protection; built-in battery disconnection protection cuts off charging and discharging within 30 seconds.
