Open Frame Chassis Power Supplies

Open frame chassis power supplies are internal AC-DC conversion units designed for direct integration into electronic equipment where space efficiency, airflow and system flexibility are key considerations. Without a fully enclosed casing, these power supplies are intended to be installed within protected equipment housings, allowing designers to optimise layout and thermal performance.

At Ideal Power, our range of open frame power supplies supports a wide selection of output voltages and power ratings suitable for industrial control systems, ITE equipment, instrumentation and embedded applications. Each model includes clear electrical specifications and compliance information to support accurate and confident product selection.

Efficient Power for Integrated System Designs

Open frame power supplies are engineered to deliver regulated DC output while maintaining high operating efficiency. Their exposed chassis design supports improved airflow within equipment enclosures, helping manage heat dissipation in compact or densely populated systems.

These units are commonly selected where internal installation is required and where mechanical flexibility is important during system design and assembly.

Common Applications for Open Frame Power Supplies

Open frame PSUs are widely used in:

• Industrial automation and control systems
• Information technology equipment (ITE)
• Measurement and instrumentation devices
• Embedded electronic systems
• OEM equipment manufacturing

Their adaptable mounting options and efficient operation make them suitable for a broad range of commercial and industrial applications.

How to Choose the Right Open Frame Power Supply

When selecting an open frame chassis PSU, consider the following:

• Output Voltage and Current – Ensure the power supply matches total load requirements.
• Mechanical Dimensions – Confirm compatibility with available enclosure space.
• Cooling and Airflow – Assess ventilation within the final equipment housing.
• Compliance and Safety Standards – Verify that the unit meets relevant regulatory requirements.

Selecting the correct open frame power supply ensures stable operation, efficient performance and reliable long-term integration within your equipment design.
