LT4275BHMS#PBF is a high voltage, efficient, and flexible power over Ethernet (PoE) Controllers specially designed for use in application and telecommunication fields. The controller is capable of delivering up to 15 amps of fault-protected and direct-current power to up to 8 separate network endpoints.The LT4275BHMS#PBF is capable of supplying power to a wide range of IP devices, making it a great solution for applications including IP cameras, wireless radios, VoIP phones, LED lighting and other PoE powered devices. It is also capable of delivering up to 15 watts of power to a single device. The controller offers many features that help ensure reliable and consistent power delivery to the endpoint devices.The LT4275BHMS#PBF works by utilizing a dual-stage power supply system, which combines four dedicated power conversion stages in order to provide power to up to 8 devices simultaneously. The controller is capable of operating under POWER over Ethernet (PoE) standards up to IEEE 802.3at levels, as well as providing up to 15 Watts of peak power. The controller has the ability to monitor the current and power levels at each endpoint device, allowing it to properly adjust the power supply. This ensures that the correct amount of power is delivered to each device while still maintaining a nominal voltage level.The LT4275BHMS#PBF also has a feature that helps protect the connected equipment from over-voltage and under-voltage situations. This feature will disconnect the controller from the power source if either situation exists for longer than a certain amount of time, protecting the equipment from being damaged by an excessive power flow. The controller also has current limiting and short circuit protection capabilities to help reduce the risk of equipment failure.The LT4275BHMS#PBF also has an integrated thermal management system that helps keep the controller running cool during heavy usage. This system utilizes a fan and heat sink paired with temperature sensor probes to adjust the internal heat level to ensure the controller remains within safe temperature limits.Overall, the LT4275BHMS#PBF is a highly efficient and flexible Power Over Ethernet (PoE) Controller that is ideal for applications across the application field and telecommunication space. The controller is capable of providing up to 15 amps of consistent and fault-protected power to up to 8 endpoint devices, and features a multitude of features that help ensure power delivery to the devices is reliable and consistent. It also features integrated thermal management, current limiting and short circuit protection, and over-voltage and under-voltage protection, making it an ideal choice for any PoE powered device.
