It provides a 13.8 V main output for the load and a separate 13.4 V charging output for a sealed lead acid standby battery. If the mains supply is lost the battery takes over automatically, which makes it the standard building block for alarm panels, access control and small CCTV installations that must keep running through an outage.\u003c\/p\u003e\n\u003cp\u003eTotal rated power is 51.38 W across both channels. The main output is adjustable from 12 to 14.5 V. A battery low cut off between 9.5 and 11 V protects the battery from deep discharge. Protection covers overload with hiccup mode auto recovery, over voltage and short circuit. The unit is fanless with free air convection cooling and carries UL 62368-1, TUV EN 62368-1, CB, CE and the Australian RCM mark.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e Mean Well\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e AD-55\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e AD-55A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Enclosed security power supply with battery charger and UPS function\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMain Output CH1:\u003c\/strong\u003e 13.8 V DC, 3.5 A rated, 0 to 4 A range\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBattery Charging Output CH2:\u003c\/strong\u003e 13.4 V DC, 0.23 A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTotal Rated Power:\u003c\/strong\u003e 51.38 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCH1 Adjustment Range:\u003c\/strong\u003e 12 to 14.5 V\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRipple and Noise:\u003c\/strong\u003e 100 mV peak to peak maximum\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput:\u003c\/strong\u003e 88 to 264 V AC or 124 to 370 V DC, 47 to 63 Hz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Current:\u003c\/strong\u003e 1.6 A at 115 V AC, 1 A at 230 V AC typical\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInrush Current:\u003c\/strong\u003e 20 A at 115 V AC, 40 A at 230 V AC cold start\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEfficiency:\u003c\/strong\u003e 71 percent\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBackup Function:\u003c\/strong\u003e Powers the load and charges the battery simultaneously.
