Power Distribution Units (PDUs) are essential components in vehicle electrical systems, responsible for efficiently distributing electrical power to various subsystems. They ensure that power is delivered safely and reliably, managing the flow of electricity to critical components such as the engine control unit, lighting systems, and infotainment modules. PDUs are designed to handle high current loads and often incorporate features like circuit protection, voltage regulation, and diagnostic capabilities. By centralizing power distribution, PDUs reduce wiring complexity, enhance system reliability, and facilitate easier maintenance. Their robust construction and advanced design make them indispensable in modern automotive applications, supporting the increasing electrical demands of today's vehicles.
