LED drivers, also commonly referred to as LED power adapters, represent a key component to any lighting schematic. They regulate the amount of power going to the LED, maintaining the LEDs lifespan and protecting them from overloads or faults. There are cases wherein AC-DC LED drivers are necessary. HLN-80H-54A is a product from MS DC to DC converters and AC to DC LED drivers. This type of LED driver is ideal for cost conscious designs in applications which require an efficient and reliable power source for running LED loads within a low profile and compact design.

The HLN-80H-54A possesses an excellent combination of features which make it a powerful and successful device. These features include its low cost, class 2 rated (double) overload and short circuit protection, its reliable semi-conductor switching, low ripple and noise, high efficiency, compact size, and its output power and voltage. It also has a no-load power consumption of less than 0.15W, which helps contribute to its greater efficiency and performance. With its 75% typical efficiency, it is one of the best of its kind, capable of providing an economical solution for small to large LED lighting projects.

The HLN-80H-54A has a wide range of potential applications, with its output voltage measuring anywhere from the minimum about 28V and maximum of 54V. These applications range from interior and exterior LED lighting, to general low voltage DC applications. Architectural lighting, landscape lighting and signage are merely a few examples of its potential applications. The HLN-80H-54A is also an ideal device for interior LED lighting applications due to its radiation performance and high efficiency.

The HLN-80H-54A possesses several unique features which separate it from its competitors. One feature in particular is the auto protection function. This function provides double output overload and short circuit protection. In this way, the device is able to protect the connection circuits and LED load during the operation. This is especially useful during an overload, as it will automatically reduce the current in order to protect the device from overheating and possible damage.

The HLN-80H-54A also possesses a number of advanced safety features. These include the short circuit protection, low output, overvoltage and over temperature protection. It also possesses a dielectric strength of 4kV (between output to casing and any two pins). In order to maintain its ideal performance and high level of safety, this device is compliant with a number of widely recognized safety standards, such as UL58, UL60950-1, CSA 22.2№60950-1. Therefore, it is a perfect AC to DC LED driver for many different applications.

The working principle of the HLN-80H-54A is based on one of the two common topologies referred to as “flyback”. In this circuit type, the output of the secondary winding of the transformer is connected to the rectifier circuit which in turn provides DC output. The primary winding of the transformer is passed through an external switch and controller input to control the on/off cycle, resulting in a regulated output. The set frequency of the device is determined by the external/internal controller and the operating switching frequency can be adjusted depending on the intended application.

In summary, the HLN-80H-54A AC to DC LED driver is suitable for a wide variety of applications from interior and exterior lighting, to general low voltage DC applications. It has a number of features which make it a successful device such as its low cost, double overload and short circuit protection, and auto protection functions. It also possesses a number of standard safety features, as well as a dielectric strength of 4kV. Its working principle is based on the “flyback” topology and, with its 75% efficiency, is capable of providing excellent performance and greater efficiency for its intended applications.
