That power density? It&rsquo;s deliberate. It means you get heat, fast. Really fast. And it all fits into a tight spot, <a href="https://o-yate.com">perfect</a> for those cramped machine bays. Going with 400V also keeps the current lower on the supply side. That&rsquo;s a big win because it lets you use smaller wiring and cuts down on voltage drop over distance. Once the tube hits its sweet spot, you get steady, predictable output. No surprises.</p>
