Introduction - MLC8000 Series Multi-Laser Controllers
The MLC8000 Series Laser Diode Controller Modules for the PRO8 platform are 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.

Burn-In System Applications
The MLC8000 Series Modules have 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 PRO8000 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 200 mA each. These modules have been field proven in demanding applications for many years.

Intuitive User-Friendly Controls
Each module provides eight independent outputs in which the laser injection current can be individually set for each laser. The current range, the hardware current limit and the operating mode (constant current or constant power mode) is set per module and thus is common for all 8 channels. The various modules of the MLC Series can be mixed and matched, along with modules from other PRO8 Series Modules, into any of the two chassis to implement a large variety of systems.

The PRO8 display menu allows to configure any module in the chassis individually. Mneumonic symbols provide user-friendly access to all operational parameters. All settings are retained in memory and automatically recalled upon powering on the mainframe as long as modules are not being moved to a different slot.

The polarity of the laser diodes (AG or CG) is factory fixed. The eight outputs are switched on together, the current control or power control is independent for each channel.

Built-in Laser Diode Protection

The MLC8000 Series Modules incorporate 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.

The current limit is accessed via a front panel trim-pot which reduces the risk of accidental adjustment.

After activating the laser power, a soft-start function smoothly increases the laser current, preventing overshoots.

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. The MLC8000 Series meets the international requirements regarding laser protection (e.g. CDRH US21 CFR 1040.10). All models include a key-operated power switch and interlock.

Connection Cables
For the MLC8000 Series there are no standard connection cables available.
