Open & DIN Power Supply Units

A reliable power supply unit (PSU) is at the heart of any dependable electrical or automation system. Whether you're powering control equipment, industrial machinery or embedded electronics, our range of open frame power supply units and DIN Rail PSUs is designed to deliver stable, efficient power where it matters most. With options for a wide range of voltages, power ratings and installation requirements, finding the right PSU for your application is simple.

What are open & DIN rail power supply units?

Power supply units (PSUs) convert mains electricity into the stable DC voltage needed to power equipment safely and reliably. From industrial automation systems to control panels and electronic devices, the right PSU helps protect sensitive components and maintain consistent performance.

Depending on your setup, you may need an open frame PSU for compact integration or a DIN Rail PSU for straightforward panel installation and maintenance.

Types of power supply unit

Different applications require different PSU designs, depending on space, power demands and installation preferences.

DIN rail PSUs

DIN Rail PSUs are designed to clip directly onto DIN rails within control cabinets and electrical enclosures. Their compact, organised installation makes them a popular choice for industrial automation, building management systems and control panels.

Open frame power supply units

Open frame power supply units are designed for integration into equipment where space may be limited. Often used inside machinery, kiosks, test equipment and embedded systems, they provide efficient power conversion in a compact format.

Choosing the right PSU

When selecting a power supply unit, it’s important to consider factors such as output voltage, current rating, power output, efficiency and mounting style. Choosing a PSU with the right specifications helps ensure reliable performance and long-term system stability.

If your application involves a control panel or cabinet, a DIN Rail PSU may offer easier installation and maintenance. For compact devices or embedded systems, an open frame solution may be the better fit.

Typical applications

Open frame and DIN Rail PSUs are widely used across electrical and industrial systems, including:

• Industrial automation and control panels
• Building management systems
• Manufacturing equipment and machinery
• Test and measurement equipment
• Embedded electronics and OEM systems

Reliable power is essential to system performance, and the right power supply unit helps ensure your equipment operates efficiently, consistently and safely.
