Meanwell DRDN40-48 DIN Rail Power Supply

The Meanwell DRDN40-48 belongs to the dependable DRD Series and is specifically engineered to improve overall system reliability through redundancy design. It supports 1+1 and N+1 redundancy configurations, featuring dual input channels and a single output, ensuring that if one 48V DC power supply fails, the other continues operation seamlessly. With a maximum output current of 40A, this Meanwell 40A DIN Rail Redundancy Module delivers consistent power flow without voltage drops, protecting sensitive equipment such as PLCs, HMIs, and control relays.

Built using advanced AC/DC conversion technology, the DRDN40-48 operates on a 48V DC input and is fully compliant with EN/UL/IEC 62368-1 safety standards for IT and AV applications. Its DC OK control signal provides real-time monitoring, allowing engineers to detect faults or voltage anomalies instantly. The compact design—measuring 55mm (W) × 125.2mm (H) × 100mm (D)—saves space in crowded panels and simplifies installation on standard DIN rails. The fanless design minimizes noise and eliminates moving parts, significantly reducing maintenance requirements.

Although the DRDN40-48 SMPS carries no IP rating, it performs optimally within enclosed electrical cabinets. Its robust construction, combined with Meanwell’s engineering precision, guarantees stable performance under continuous load conditions. Every component, from its dual-channel input architecture to its high-current handling capacity, is designed to extend system uptime and safeguard mission-critical automation systems. Engineers trust this module for its proven efficiency, global certification, and field-tested reliability across industries.

The Meanwell DRDN40-48 SMPS is widely used in industrial automation systems, PLC control panels, machine tool controllers, and server power backups that require uninterrupted 48V DC power. It serves as a vital link in redundant power configurations, ensuring that even if one SMPS fails, power continues without interruption. This reliability is critical in sectors such as factory automation, process control, and building management systems, where downtime can cause production losses or equipment malfunction.

Panel builders and maintenance engineers prefer the DRDN40-48 for its straightforward DIN rail mounting, real-time DC OK signal, and minimal wiring complexity. The module’s compact form allows easy integration in tight panels, and its redundancy capability helps engineers design fail-safe electrical architectures. Students and young engineers studying redundant SMPS systems or power reliability engineering often refer to the DRDN40-48 datasheet for practical understanding of dual-channel DC distribution, load sharing, and control signaling.

The Meanwell DRDN40-48 is often searched under variations such as DRDN40-48, DRDN40 48, meanwell DRDN40-48, and DRDN40-48 meanwell. It is one of the most trusted Meanwell 40A DIN Rail Redundancy Module models, ensuring fault-tolerant operation for high-availability systems. Engineers looking for the DRDN40-48 datasheet, DRDN40-48 manual, or updated DRDN40-48 price can refer to Meanwell’s official platform or authorized industrial distributors. With its precision design and high reliability, the Meanwell DRDN40-48 SMPS continues to set a benchmark in power redundancy for industrial automation and energy management systems.
