There are several factors to consider when selecting a power supply that delivers the high voltages often needed by large and complex high-performance systems. For almost all electronic products and systems, high reliability should be expected. Still, in some markets, reliability cannot be compromised or a trade-off for other performance factors. In particular, mission-critical industrial […]
