DIN rail power supply 120W 48V 2.5A SDR-120-48

Universal DIN rail mounting power supply

The SDR-120-48 is a reliable 48V DC power source with a power of 120W, designed for use in industrial automation, monitoring systems, control systems and anywhere a stable and safe power supply is required. Mounting on a DIN TH35 rail simplifies installation in control cabinets and switchboards. The device is characterized by high efficiency, compact dimensions and a wide range of protections.

Design and functionality

The power supply has been designed for durability and ease of use. The housing, only 40mm wide, allows for efficient use of space inside cabinets. Built-in protections protect both the power supply itself and the devices connected to it from overloads, short circuits, overvoltages and overheating. Additionally, an LED indicates correct operation of the power supply. The active PFC (Power Factor Correction) function improves energy efficiency and reduces harmonic distortion in the power grid. The ability to briefly overload to 150% of the rated power for 3 seconds allows for trouble-free starting of devices with high inrush current.

Applications and benefits

The SDR-120-48 power supply is used in:

• Industrial automation: powering PLC controllers, sensors, valves and other automation devices.
• Monitoring systems: powering industrial cameras, DVR/NVR recorders.
• Alarm systems: powering alarm control panels, motion detectors, door/window opening sensors.
• LED lighting: powering LED luminaires with a voltage of 48V DC.
• Telecommunication devices: powering routers, switches, modems.

Thanks to the high efficiency (up to 91%), energy losses are minimized and operating costs are reduced. A three-year warranty provides peace of mind and confidence in reliable operation for a long time. Compliance with safety and electromagnetic standards confirms the high quality of the product and its safe use. A wide input voltage range (88-264V AC / 124-370V DC) allows operation in various network conditions.
