• Simultaneous Current Control for 8 Diodes
• Built-In Laser Diode Protection
• Operation of Up to 64 Laser Diodes with One PRO8000 Chassis

The MLC8100-8CG Laser Diode Controller Module for the PRO8 platform is designed to control up to eight lasers from a single laser diode controller module. When fully populated, a PRO8000 Chassis can simultaneously power up to 64 laser diodes. The MLC8100-8CG Module has been designed for burn-in applications. The high density (64 lasers / chassis) drive capability coupled with the user-friendly advanced control features of the PRO8000 Mainframe make this product line an ideal choice for this application. This series provides eight different maximum drive current ranges. The PRO8100-8CG Chassis can support up to a total of 16 A of laser diode drive current - the sum of the output drive currents from all installed modules - and can therefore easily support the demands of driving 64 lasers at 100 mA each.

The MLC8100-8CG Module incorporates proven laser protection features to safeguard sensitive laser diodes. These features include a hardware current limit, a soft start circuit, and an interrupt sensing circuit that can detect a break in the connectors going to the laser diode, and then shut the driver down. Additionally, extensive precautions have been taken to protect the laser diodes during AC power interruptions or outage. When switched off, all lasers are electronically shorted. Even in case of an AC power interruption, the laser current remains transient-free. Voltage peaks on the AC line are effectively suppressed by electronic filters, shielding of the transformer, and careful grounding of the modules and chassis.
