Product information "LDxCHA Laser Diode Drivers"

Output Current LD 2.5-15 A; Chassis Mount; Compatible with Type A & B Lasers

Wavelength Electronics’ LDxCHA series of low noise module type laser diode drivers provides current levels from 2.5 A up to 15 A. The following models are available: LD2.5CHA (2.5 A), LD5CHA (5 A), LD10CHA (10 A), or LD15CHA (15 A).

These drivers meet laser compliance requirements from 3 V with a single 5 V supply, and up to 28 V with an additional 30 V power supply, supporting applications such as materials processing, industrial laser cutting, and laser diode bars / stacks. This product family supports A & B type laser diodes.

The new circuitry in the LDxCHA allows for the laser diode current limit and the laser diode current setpoint to be fine-tuned without output current enabled to the laser. This allows users to set the specific safety and output levels required without risk of overdriving the laser during initial configuration.

The LDxCHA drivers, with their small size and easy mountability, can be attached directly to an optics table or designed into a system. Two trimpots set the current limit and current setpoint, while five spring loaded terminal blocks allow for simple wiring.

Built-in safety features ensure robust designs for real world operating conditions: clipping current limit ensures that the output current will never exceed the setpoint; and slow start circuit ramps the output current. Thoughtfully designed features provide valuable benefits and protect the laser against operational anomalies.
