DIN Rail Power Supplies – Efficient & Reliable Solutions for Automation, Smart Homes and Industry
DIN rail power supplies are essential components in modern industrial automation systems, home automation (smart home) installations, and other technical environments. At Electrónica Embajadores, we offer a wide range of switched-mode power supplies (SMPS) for DIN rail mounting, designed to deliver stable, efficient power in a compact and easy-to-integrate format for control cabinets, switchboards and electrical panels.
These industrial power supplies convert alternating current (AC) into direct current (DC) with high energy efficiency and low ripple, making them ideal for powering PLCs, sensors, actuators, communication modules, and industrial controllers.
Key Technical Features
- High Energy Efficiency
Our DIN rail power supplies use advanced switching technology to achieve efficiencies above 90%, reducing heat generation, improving energy savings, and extending the lifespan of connected equipment.
- Low Ripple Output
Low ripple ensures a stable and clean DC output, which is vital for sensitive control electronics. It minimises interference and guarantees system reliability.
- Wide Input Voltage Range
Most models accept a wide input voltage range, typically from 85V to 264V AC, making them suitable for various installation environments, even those with unstable or fluctuating mains supply.
- Adjustable Output Voltage
Many power supplies offer a ±10% adjustable output voltage, which allows compensation for voltage drops over long cable runs or adjustment to suit specific equipment needs. Always check the individual model specifications.
- Built-in Protection
Our DIN rail power supplies include integrated protection against short-circuits, overloads, overvoltage, and overheating, ensuring maximum safety and durability in demanding applications.
Common Applications
DIN rail-mounted PSUs are extremely versatile and widely used in:
- Industrial automation: powering PLCs, sensors, relay modules, motor controllers, HMIs, and more
- Home automation (smart homes): lighting control, HVAC systems, automated blinds, security cameras, and alarm systems
- Electrical cabinets and panels: safe and efficient power distribution in modular systems
- Robotics and machinery: motor drivers, motion controllers, and I/O modules
- Industrial communication systems: routers, switches, gateways and IoT nodes
Whether you’re looking for a 24V DIN rail power supply, 12V or even 48V models, our range covers a variety of voltage and power levels.
How to Choose the Right DIN Rail Power Supply
Before selecting a DIN rail PSU, consider these key factors:
- Required output voltage: commonly available in 5V, 12V, 24V, 48V DC
- Power rating: calculate total load and add a safety margin (typically 20-30%)
- Type of load: resistive, inductive or capacitive
- Environmental conditions: temperature, humidity, enclosure ventilation
- Available installation space
- Compliance and certifications for your application
For harsh or demanding environments, choose industrial-grade power supplies with proper safety and EMC certifications.
