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 to 150A and beyond. Intensify is intended for OEM applications such as fiber laser pumping, laser tooling and laser diode burn-in.

Overview[edit | edit source]
Nx50 is one of the first laser diode drives deploying an state of the art high frequency three-phase switching converter. Each driver has three switching regulator running in separate time phases to minimize output ripple and passive component sizes.
- Designed for CW/QCW laser bar driving
- 50 A, 250 W constant output per board
- Small form factor of 94×77.5 mm / 3.7"×3.1"
- Parallel by stacking, scale to 150 A and beyond
- Laser diode current & voltage spike protection
- Overtemperature, undervoltage, ESD and short circuit proof
- Fully differential analog 0-10 V setpoint input
- Current and voltage monitor 0-10 V outputs
- Pulsing via digital pulse input or analog modulation
- OEM friendly pricing
