Power supplies are the backbone of any reliable industrial control system, converting mains AC voltage into the stable DC voltage required by PLCs, sensors, relays, and other automation components. In this category, you will find a curated selection of DIN rail mountable switched-mode power supplies from FINDER, a brand synonymous with precision and durability. These units typically offer single-phase input (100-240 VAC) and provide regulated outputs at common voltages such as 12 VDC or 24 VDC, with power ratings ranging from a few watts up to several hundred watts. Key technical features include high efficiency (often >85%), short-circuit protection, overload protection, and a wide operating temperature range suitable for industrial environments. The compact design allows for easy installation in standard electrical cabinets, and many models include LED indicators for status monitoring. Whether you need a basic unit for a simple sensor network or a robust supply for a complex automation cell, this range covers your requirements with the reliability that FINDER guarantees.
These power supplies are primarily deployed in industrial automation panels, building management systems, and process control cabinets. They are essential for powering programmable logic controllers (PLCs), human-machine interfaces (HMIs), distributed I/O modules, and field devices like proximity sensors and actuators. In commercial settings, they are used in access control systems, lighting control, and HVAC automation. The DIN rail form factor ensures they integrate seamlessly into existing electrical infrastructure, while the wide input voltage range makes them suitable for installations in regions with unstable mains supply. Additionally, they are commonly found in renewable energy systems, such as solar inverters and wind turbine controllers, where reliable DC power is critical for operation.
Within this category, the main subcategories include single-phase power supplies (e.g., FINDER 78.12.8.230.2400, a 24 VDC 2.4 A model) and three-phase units for higher power demands. The article codes typically follow a pattern like 78.xx.8.xxx.xxxx, where the first two digits indicate the series (78 for power supplies), the next two denote the output voltage and current, and the final digits specify the input voltage range and packaging. For example, 78.12.8.230.2400 indicates a 24 VDC output with 2.4 A current. Other notable codes include 78.12.8.230.1200 (12 VDC, 1.2 A) and 78.12.8.230.4800 (24 VDC, 4.8 A). These units are available with screw or spring-cage terminals, and some models offer additional features like remote on/off or DC OK relay contacts.
