Depending on the intended use, an open frame power supply might comprise a frame without a cover, a simple chassis plate, or even just a separate PCB. The power spectrum is very broad and the design can also be customised to particular industries, such as those in the medical or manufacturing industries.
In what is recognised by the industry as an open frame format, typically AC-DC power supplies are supplied. Open frame typically is defined as a device that is a build-only PCB, a part power supply to be inserted into an end application that supplies the whole product with the enclosure.
When choosing an open frame power supply, there are a variety of factors, but they are essentially related to the following three main areas:
1. Safety
2. Electromagnetic Compatibility (EMC)
3. Thermal management
The required creep and clearance distances to the equipment enclosure on all faces of the supply should be observed when mounting the power supply. Spacing issues will cause last-minute failure if the dimensions of the open-frame power supply are not considered at the design level. Inside the equipment enclosure, installing an open-frame power supply requires close consideration of clearance and creepage distances on both sides. As calculated, along with the layer of any insulation that is present, creepage refers to a path between a conductive component and the boundary of the equipment casing. Insulation can build a conductive path that can trigger a short circuit and fires can be triggered by shorts, so a good technique is to follow a gap that prevents creeping.
There is no enclosure on an open frame which would often serve to shield electromagnetic interference. EMC control technology aims to suppress noise created by electronics, as well as protect the electronic system against external noise. For appliances or machines, input and output wiring can be mounted far apart, while still preventing location near the open-frame power supply.
Open frame power supplies may have a power rating when cooled by convection, air-cooled by force, or both. An open-frame power supply represents compliance with requirements as-is, with no containment included facilitating heat build-up. The thermal efficiency of the power supply will be influenced by several specific variables arising from the operation, such as the space around it, heat dissipation of neighboring parts, mounting location and direction, the load to be applied and the equipment cooling available.
The mounting location, accompanying space and surrounding parts are specific to each application, along with any air cooling, so it is vital to verify the working temperature of key components after they have been assembled. This guarantees that their overall scores are not exceeded by the safety-critical elements and that reliability and service life are not compromised.
