That&rsquo;s not just a random set of numbers. Here&rsquo;s the why: running at 400V keeps the current lower for the same wattage. That means less voltage drop across the line, and you can get away with smaller wiring. And the 300mm length? It gives you enough surface area to blast 2500W of heat into a tight zone—without having to build a bulky, oversized assembly.</p>
