Power Supplies: Have you ever considered the benefits of models with dual rating?

Switching power supplies with dual rating offer compact, lightweight, and cost-effective solutions without compromising the performance and reliability of the device.

When there is a need for power supplies for systems that require higher power peaks than a normal power supply for short periods, one generally opts for expensive, bulkier, and more powerful products.

Typical applications falling into this category may include:

• Printers
• Pumps
• Engines

Generally used in the following sectors:

• Industrial automation
• Medical devices
• Robotics
• Power tools
• Packaging, testing, storage systems, and printers

In applications like these, the average power demand is well below the starting peak. By opting for an ac/dc power supply with lower power consumption compared to the initial peak power, a more compact, lighter, and certainly more economical power supply can be installed.

Such reductions and savings in terms of space and consumption would not compromise the reliability and long-term use of the devices. If the device is correctly certified and safe to withstand initial power peaks, it can be easily installed in systems with requirements similar to those illustrated earlier.

Power supply models with dual rating are evaluated both on the higher power rating and thermally for air cooling. This is ideal for applications requiring power peaks, where the peak does not exceed the fan cooling rating, and the average load is lower than the free air cooling rating.

In general, the wider the difference between fan cooling and free air cooling, the more the peak load capacity is reduced. Industrial power supplies with dual rating normally specify the components and their temperature rating to ensure safe and reliable operation. It is important to pay attention to this information so that the product does not overheat during
