Model S20013.8 DC Switching Power Supply Regulated 13.8V, up to 15A (200W) Overview This DC switching power supply provides a stable 13.8V DC output for monitoring, security, intercom, and access control systems. It is built for continuous indoor use with selectable AC input and multiple protection features to protect connected equipment and the power supply itself. Key benefits Regulated output: Delivers a stable DC 13.8V output suitable for cameras, DVRs, access control panels, intercoms, and other 12Vclass devices. Capacity options: Available configurations include 140W (10A) and 200W (15A) capacity. The S20013.8 model provides up to 200W and 15A continuous output. Reliable protection: Builtin short circuit, overload, and overvoltage protection. When output current exceeds the rated value the unit will automatically cut off output to prevent damage. Input flexibility: AC input selectable between 110V and 220V via switch, with tolerance of ±15% and support for 50Hz and 60Hz mains. Reduced inrush and stable startup: Softstart circuitry reduces AC input impact at poweron, protecting upstream circuits and fuses. Quality assurance: 100 percent fullload burnin test performed to ensure stable operation under continuous load. Compact footprint: Measures 199 x 98 x 42 mm, allowing installation in cabinets and enclosure spaces with limited depth. Specifications Model: S20013.8 Input voltage: AC 110V or 220V selectable by switch, tolerance ±15% Input frequency: 50Hz/60Hz Output voltage: DC 13.8V Output current: 0 to 15A (200W version); 10A for 140W version Output power: 140W or 200W options; listing corresponds to up to 200W Output type: Single output Output terminals: AC input poles L N FG; DC output terminals V V +V +V for multiple connections or load distribution Size: 199 x 98 x 42 mm Operating characteristics: efficiency, low operating temperature, softstart, fullload burnin tested Protection and safety features Overload protection: Automatic cutoff when load exceeds rated current to prevent damage. Short circuit protection: Immediate response to short circuits on the DC output. Overvoltage protection: Prevents output voltage from rising above safe limits. Grounding: FG terminal for protective earth connection; follow local wiring codes when grounding. Environment: Designed for dry, ventilated indoor use only. Do not place near sources of heat, moisture, or flammable materials. Installation and use guidance Select input voltage before powering: Set the AC input switch to the correct 110V or 220V position prior to connecting mains. Wiring: Use appropriate wire gauge for the load current and ensure secure terminal connections. Use both +V and V terminals for load distribution when needed. Plugging and unplugging: Turn off attached equipment before making or breaking connections to avoid sparks. Load planning: Sum the power requirements of all connected devices and choose the converter capacity accordingly. Allow margin above the total device draw to avoid frequent tripping. Operating environment: Install in a dry and ventilated location. Avoid exposure to humidity, temperature, or corrosive atmospheres. Practical applications CCTV systems: Power multiple cameras and recording equipment while maintaining steady voltage for consistent image quality. Access control and electric locks: Supply stable power to door controllers, magnetic locks, and related peripherals. Intercom and monitoring panels: Provide reliable 13.8V supply for communication panels, alarm sensors, and internal electronics. What makes it stand out Selectable mains input and softstart reduce installation complexity and protect upstream circuits. Multiple output terminals allow convenient distribution and parallel connections for several devices. Comprehensive protection features and fullload burnin testing increase reliability in continuoususe security and access control environments. considerations Confirm whether the 140W or 200W capacity meets your total system power requirement. Ensure correct input voltage selection and proper grounding during installation. Use in dry, ventilated indoor spaces and follow the provided protection and wiring guidance for safe operation.
