00:00 - Hi, I'm Zac from High Performance Academy and welcome to our Power Management Unit Configuration course.
00:06 This course will teach you about PMUs, what they are, why we use them and the massive benefits they offer when we're building the electrical systems in our cars.
00:15 We're going to discuss the technical theory required when specifying and configuring a PMU for your project and follow this up by putting that theory into practice with several real world examples of PMUs being used in performance automotive applications.
00:28 Before we go any further, we need to clear up some terminology around this subject.
00:33 There are a few common names given to the devices that we'll be working with in this course.
00:38 We're going to refer to them as power management units or PMUs but if you see the names power distribution unit, PDU or power distribution module, PDM, rest assured that these are just different names for the same type of device.
00:52 This will be very clear when you're at the stage of specifying a device for your project but it's best that we mention it now to avoid any confusion down the line.
01:01 Installing and configuring PMUs is a relatively advanced topic and some prior automotive electrical knowledge is assumed.
01:08 While we do cover most of the required basic electrical theory in this course, if you're completely new to the automotive electrical world, I would suggest having a look at our Wiring Fundamentals course before diving into this one.
01:21 It assumes no prior knowledge and provides a solid foundation on which this PMU configuration course builds.
01:27 Using a PMU in your project does require a lot of up front planning to make sure a device with enough inputs, outputs and features is specified.
01:36 But this isn't typically any more complex than the planning required for a more conventional power distribution setup using relays and fuses.
01:43 In fact, using a PMU will likely result in an easier to understand system overall.
01:48 You'll also drastically increase the flexibilty of your system because when a module or device receives power, it's no longer hard wired to a particular switch or trigger signal and any changes can be made in the software rather than having to physically modify the wiring harness.
02:06 During this course, we'll be talking about logical functions such as " statements" "and statements" and "if statements" as well as covering terms like latching, flashes and timers.
02:17 Don't let any of these terms put you off though, they'll all be explained in relatable ways and once you have an understanding of them, they'll become second nature as you configure your PMU.
02:26 Understanding the fundamental operation of a PMU is not particularly complex but as you'll see, when we start combining these basic functions together, we can configure a PMU to perform very complex logic.
02:39 Because of this, the course is broken up into distinct sections that build on top of one another to give you a complete understanding of not just the basics of PMU configuration but also a good understanding of how they can be configured to perform those more complex tasks.
02:55 In the first course section we'll cover some general purpose electrical theory that'll be essential background knowledge to have when designing a performance automotive electrical system.
03:04 In the second section we cover topics specific to the installation and configuration of a PMU in your project.
03:10 Allowing us then in the 3rd section to detail some case studies of using those basic PMU functions to perform more complex operations.
03:20 Finally we outline the HPA PMU configuration 6 step process.
03:25 This is going to give you a solid guide on Installing and configuring a PMU in your project.
03:30 This is followed up by worked examples of this process being put to practice in the real world to give you the confidence to tackle a PMU installation in your own project.
