Stamping Heatsink Plates for Open Frame Power Supply

The open frame power supplies offering versatile output voltages, minimal leakage current, and compliance with international safety standards. The range of low to medium power AC-DC open frame power supplies extends from 10 watts to 800 watts, and offers an exceptionally wide variety of configuration options. Most of these power supplies are available with a choice of single or multiple isolated outputs with numerous different voltage combinations, and a considerable number also provide auxiliary outputs for powering fans and standby circuits.

Open Frame Power Supply with Heatsink

The open frame power supply does not have a closed casing, and its internal circuit components such as transformers, capacitors, inductors, rectifier diodes, etc. are partially or completely exposed. This design makes the power supply have better heat dissipation performance, because the heat can be directly dissipated into the surrounding environment, unlike the closed power supply which is restricted by the casing. For example, in some industrial equipment that does not require high space but has strict heat dissipation requirements, the open frame power supply can effectively dissipate heat and avoid power failure due to overheating.

Although it is an open structure, it usually has a relatively compact size. This is to facilitate installation inside various equipment and provide power support for equipment in a limited space. For example, in some small electronic equipment test benches or communication equipment racks, the open-frame power supply can fit the space well and power the equipment.

All low to medium power AC-DC power supplies are high efficiency switch-mode designs and feature a universal AC input, making them suitable for use almost anywhere in the world. These open frame power supplies are ideally suited to applications in communications, computing, storage, business systems, test, instrumentation and industrial equipment. Many of the supplies are also available with medical approvals, for applications such as patient monitoring systems and other equipment used in medical wards and surgical operating theaters.
