AC DC adapters, such as the GSM90A15-P1M, are devices used to convert an alternating current (AC) power source to a direct current (DC) form. They can also be referred to by other names, such as power converters, line power adapters, and wall plug-in adapters. There are many applications where AC DC adapters can be used to help meet the power and voltage requirements of the specific device or product.

The GSM90A15-P1M is a desktop AC DC adapter, produced by JPI, that is designed for operating in the 90-264VAC range and provides an output of 15VDC/600mA. This desktop adapter is supplied with a 1 metre detachable power cord with fly lead and a UK 3-pin plug. The input fuse is covered and protected for safety, and there is internal over voltage and short circuit protection. An LED indicator is also set on the power adapter to indicate the power status.

The primary purpose of the GSM90A15-P1M is to supply power to electromagnetic locking devices and access control systems. This includes applications such as motorised locks, strikes, magnets, door openers, and other similar devices. It can also be used with other desktop electronic devices and products that require a constant current source.

The GSM90A15-P1M has a smart power conversion system that is able to automatically adjust itself to the input voltage, making it suitable for use in both international and local power systems. This adapter provides a clean, stable DC output that is safe and reliable. The output voltage is only slightly adjustable, making it an ideal choice for applications where stability and consistency are important.

The working principle of this adapter is based on a flyback circuit design. This is a type of electrical converter that allows for the switching of power from one DC source to another with the use of inductors. In this case, the converter is used to convert the AC power source into a lower DC input which is then outputted in the required voltage. This is achieved by using an integrated controller chip to regulate the switching sequence, as well as a transistor for power switching. The power is then converted through an inductor where the output is regulated and inverted into a DC form.

The GSM90A15-P1M is a reliable and efficient AC DC adapter that can be used in many applications. Its efficiency and safety features make it a perfect choice for applications such as access control systems and other desktop electronic devices.
