High power laser diode driver with parallel connection capability

Granite Devices Granite Devices, has released a new kind of high power laser diode driver for OEM market. Intensify Nx50 has unique parallel connection capability to scale up continuous and pulsed output current rating to 150A and beyond. Intensify Nx50 accepts standard 12 V DC input voltage while output current is adjustable from 0 to 50A per Nx50 device. Maximum output voltage of 5.0V allows driving up to two laser diodes in a series connection. Intensify is one of the first laser diode drives employing high frequency three-phase switching converter to minimize output ripple and physical size. Due to this construction, Nx50 yields record breaking efficiency of 96 per cent thus eliminating the need of active cooling. Cool running devices also exhibit unforeseen durability of 1.2 million hour MTBF. The device includes under voltage, over temperature, ESD and laser diode protections as standard feature. The driver is targeted for OEM laser diode applications such as optical pumping, material processing and printing where reliability and cost are critical factors. Intensify is available worldwide through Granite Devices web shop for €273/pcs at 50pcs quantity.
