CH1 supplies the load at 41.5V (up to 1.9A) while CH2 charges an external 36V battery at 41.5V \/ 1A. When AC mains fails, the unit switches to UPS mode and the battery takes over the load; a battery cutoff at 32V ±0.5V protects the battery from deep discharge.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCH1 load output 41.5V, 1.9A rated (0–2.9A); CH2 battery charger 41.5V, 1A\u003c\/li\u003e\n\u003cli\u003eBuilt-in UPS function: automatic switch to battery on AC failure\u003c\/li\u003e\n\u003cli\u003eBattery cutoff 32V ±0.5V; battery reverse polarity protection (an external fuse in series with the battery is required)\u003c\/li\u003e\n\u003cli\u003eSignal outputs: AC OK, battery low, battery full, battery disconnect\/reverse polarity, discharge (TTL)\u003c\/li\u003e\n\u003cli\u003eInput: 90–264VAC \/ 127–370VDC\u003c\/li\u003e\n\u003cli\u003eProtections: overload, over voltage, over temperature\u003c\/li\u003e\n\u003cli\u003eTypical efficiency 88%\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eOutput\u003c\/th\u003e\n\u003cth\u003eVoltage\u003c\/th\u003e\n\u003cth\u003eRated current\u003c\/th\u003e\n\u003cth\u003eCurrent range\u003c\/th\u003e\n\u003cth\u003eRipple \u0026amp; noise (max.)\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCH1 (load)\u003c\/td\u003e\n\u003ctd\u003e41.5V\u003c\/td\u003e\n\u003ctd\u003e1.9A\u003c\/td\u003e\n\u003ctd\u003e0–2.9A\u003c\/td\u003e\n\u003ctd\u003e240mVp-p\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCH2 (battery charger)\u003c\/td\u003e\n\u003ctd\u003e41.5V\u003c\/td\u003e\n\u003ctd\u003e1A\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eLAD-120C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eLAD-120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal rated power\u003c\/td\u003e\n\u003ctd\u003e120.35W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCH1 voltage adjustment\u003c\/td\u003e\n\u003ctd\u003e32.4–43.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery cutoff\u003c\/td\u003e\n\u003ctd\u003e32V ±0.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput\u003c\/td\u003e\n\u003ctd\u003e90–264VAC \/ 127–370VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficiency (typ.)\u003c\/td\u003e\n\u003ctd\u003e88%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorking temperature\u003c\/td\u003e\n\u003ctd\u003e-20 to +60°C (-4 to 140°F) ambient, derating per datasheet curve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e159 × 97 × 30 mm (6.26 × 3.82 × 1.18 in) (L × W × H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.42 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003eTypical applications: security and access-control systems, fire alarm panels, emergency and backup-powered equipment.\u003c\/p\u003e\n\u003cp\u003eDatasheet: \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0681\/4675\/7799\/files\/LAD-120-spec.pdf?v=1772468153\"\u003eLAD-120 series specification (PDF)\u003c\/a\u003e.
