Din Rail Power Supplies
Din Rail Power Supplies
DIN rail power supplies are compact, panel-mount AC/DC converters designed to snap onto standard DIN rails inside electrical cabinets and control panels. They convert incoming AC mains voltage — typically 85–264 V AC — into stable DC output voltages such as 12 V, 24 V, or 48 V DC to power PLCs, sensors, relays, HMIs, and other industrial electronics. Their standardized mounting format simplifies installation and replacement in automation environments.
These power supplies are widely used across industrial automation, building management, machine control, and process instrumentation. Engineers select them based on output current capacity, input voltage range, efficiency class, and compliance with standards such as IEC 61010 and UL 508.
Typical Applications
- Industrial automation: powering PLCs, I/O modules, and field devices in manufacturing cells
- Building automation: BMS controllers, access control panels, and HVAC systems
- Machine control: CNC machines, robotics, and conveyor systems
- Process instrumentation: transmitters, flow meters, and sensors in process plants
- Transportation infrastructure: rail signaling and traffic management systems
