DIN rail power supply 15.4W 48VDC HDR-15-48

DIN Rail Power Supplies – Reliable Power in a Compact Housing

The HDR-15-48 DIN rail power supply is a solid and efficient power source, ideal for applications in industrial automation, monitoring systems, control, and all types of devices requiring a stable 48V DC voltage. It belongs to the HDR-15 series from MEAN WELL, which is characterized by reduced dimensions and improved efficiency compared to the previous DR series. This makes this power supply particularly suitable for situations where mounting space is limited.

Design and Functionality

The HDR-15-48 power supply is designed for mounting on a standard TS35 DIN rail (7.5 or 15 mm), making it easy to integrate with existing installations. Cooling is done naturally – by air convection – which eliminates the risk of failure related to fan damage and ensures quiet operation. Built-in protections against overload, short circuit, and overvoltage guarantee safe and reliable operation of the device and protect the connected circuits. An LED indicates the correct operation of the power supply.

Applications and Benefits

This 15W power supply model with a 48V DC output voltage (0.32A current) is perfect for powering various devices, such as:

• Alarm and monitoring systems
• PLC controllers
• Sensors and transducers
• Industrial cameras
• Building automation devices
• Other applications requiring a stable 48V DC voltage

It is worth noting that MEAN WELL power supplies are characterized by high energy efficiency (up to 87% for the HDR-15-48 model), which translates into lower operating costs. Additionally, the operating temperature range from -30°C to +70°C allows them to be used in harsh environmental conditions. The power supply complies with UL-60950-1/508/1310 and EN60950-1/61558-2-16 standards, confirming its safety and quality. The design based on Class II insulation eliminates the need for grounding. No-load power consumption is very low – below 0.3W.
