Model S20013.8 Switching Power Supply 13.8V DC, 10A or 15A (140W or 200W) Description This compact switching power supply delivers a stable 13.8V DC output for LED lighting, monitoring, security systems, intercoms, and access control equipment. It is available in two output options: 10A (140W) and 15A (200W). The unit accepts AC110 or AC220 input selected by a switch and is designed for continuous operation with protections and features that minimize disturbance to the AC supply. Key specifications Model: S20013.8 Output voltage: DC 13.8V Output current options: 10A (140W) and 15A (200W) Output power range: 101 to 200W Input voltage: AC 110/220 plus or minus 15 percent, selectable by switch Input frequency: 50Hz or 60Hz Output type: Single Terminal layout: Input L N FG; Output terminals V V +V +V Size: 199 x 98 x 42 mm Why choose this power supply Stable 13.8V output for equipment that requires consistent DC power. Switchable AC input lets you use common mains voltages without rewiring. Builtin protections for short circuit, overload, and overvoltage to protect connected devices. If output current exceeds the rated value, the unit will automatically cut off the output. Soft start reduces inrush current and minimizes impact on the AC supply during power up. efficiency design supports lower operating temperature for reliable continuous use. Each unit undergoes fullload burnin testing to verify performance before shipment. Practical use scenarios Security camera systems: Provide continuous 13.8V DC power to CCTV cameras and recorders in surveillance installations. Access control and intercoms: Power door controllers, electric strike systems, and intercom units that require a stable DC supply. LED and monitoring installations: Run LED drivers, monitoring sensors, and related control equipment that need a constant 13.8V source. Installation notes Select the correct AC input position with the voltage selector switch before applying mains power. Observe polarity when connecting devices to the +V and V output terminals. Use the provided ground FG terminal to connect system ground as required by the installation. This power supply is suited for professional installations that require a compact, reliable 13.8V DC source with overload and fault protection.
