Laser diode bars and matrixes pumping current generator
SVETINFO-I
 

Application

Universal generator SVETINFO-I provides current pulses with amplitude up to 350A for laser diode bars and matrixes (LDB and LDM) in-feeding. Autonomous and external guide (PC with USB interface) moedes are foreseen.

Unified command system allows to integrate SVETINFO-I into LDB/LDM characteristics measurement and climatic/endurance survey automated sets.

Active power corrector in integrated PSU provides protection from input power overvoltage and robustness to high power line noise.
