Introduction to DIN Rail Power Supplies

A DIN rail power supply is a compact, rail-mounted device that converts electrical input (AC/DC) into regulated output for industrial equipment. Designed to fit standardized DIN rails (35mm width per ISO 60715), these units simplify installation in control panels, PLC cabinets, and automation systems.

Key Features:

• Space Efficiency: Saves 30–50% panel space compared to traditional PSUs.

• Universal Input: Operates at 85–264V AC (single-phase) or 18–60V DC.

• Robust Design: IP20-rated enclosures resist dust and humidity.

Core Components & Technical Specifications

Technical Breakdown

Critical Components:

• EMI Filters: Reduce electrical noise (e.g., FEAS GmbH’s PSGK10 model).

• Protection Circuits: Overload, short-circuit, and over-temperature safeguards.

• DC OK Signal: Alerts system failures (JVL’s PSU05-045).

Industrial Applications & Case Studies

Real-World Use Cases

• Factory Automation: Powers PLCs, sensors, and actuators in automotive assembly lines (e.g., ifm electronic’s DN4013).

• Energy Infrastructure: Supports Cisco’s 480W DIN rail PSUs for industrial routers in smart grids.

• Emergency Systems: Integrates with uninterruptible power supplies (UPS) for backup in data centers.

Case Study: Shenzhen’s Live-Line Robot (2025)
A dual-arm robot powered by DIN rail PSUs performed 10kV line maintenance, reducing human risk and boosting efficiency by 40%.

How to Choose the Right DIN Rail Power Supply

Selection Checklist

1. Input/Output Requirements: Match voltage/current to load (e.g., 24V/10A for motors).

2. Environmental Conditions: Opt for conformal coating in humid areas.

3. Certifications: UL 60950-1, CE, and RoHS compliance.

4. Scalability: Leyu’s modular designs allow easy upgrades Product Page.
