+ | '''Intensify Nx 50''' is a compact stackable constant current laser diode bar driver featuring the latest multiphase switched-mode topology delivering up to 50A continuous current at unforeseen efficiency. Parallel capability allows stacking multiple Intensify boards to scale up the current up to 150A. Intensify is intended for OEM applications such as fiber laser pumping, laser tooling and laser diode burn-in. | ||
