The unit provides a SELV (Safety Extra-Low Voltage) isolated output across a 3-200VDC range, allowing it to power a wide range of LED fittings at their rated emergency wattage for a minimum 3-hour duration during mains failure.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial, retail, hospitality and public buildings where Building Regulations require emergency lighting compliance, the pack fits inside ceiling voids or behind luminaire housings where there is clearance for its 270 x 68 x 38mm casing. The DALI control interface allows the unit to communicate with building management systems for centralised monitoring, reporting test results and fault alerts without manual intervention.\u003c\/p\u003e\n\u003cp\u003eThe constant-power topology maintains stable output wattage throughout the 3-hour emergency discharge cycle, preventing the LED output from fading as battery voltage drops. The self-test function runs automated function and duration tests at programmed intervals, logging results to DALI-compliant control systems. The IP20 enclosure is rated for Zone 3 bathroom use only (outside shower zones) and general indoor applications.\u003c\/p\u003e\n\u003cp\u003eThe unit weighs 0.65kg and requires a minimum clearance envelope of 280 x 75 x 45mm when allowing for cable connections and fixing lugs. Emergency output voltage is field-adjustable via internal DIP switches to match the connected LED load, with the module drawing from an internal NiMH or LiFePO4 battery pack (cell chemistry varies by model variant).\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLED or Halogen\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eZone\u003c\/td\u003e\n\u003ctd\u003eSuitable for use in Zone 3 only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is constant-power driver technology?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eConstant-power means the unit maintains stable wattage output throughout the 3-hour emergency period, preventing the LED from dimming as battery voltage drops.
