LDxCHA Series

The LDxCHA product family has current levels from 2.5 A up to 15 A. The following models are available: LD2.5CHA (2.5A), LD5CHA (5A), LD10ACH (10A), LD15CHA (15).

Additional information

  • 2.5, 5, 10 & 15 A Output Options
  • Single supply operation at +5 VDC for single emitters (3 V maximum to laser)
  • Dual supply operation up to +30 VDC (28 V maximum to laser)
  • Constant Current or Constant Power Mode
  • Adjustable clipping current limit
  • Slow-start and delay circuitry
  • Brownout protection
  • Over-voltage protection
  • Bandwidth 600-1080 kHz (3 dB at Full Current, Constant Current Mode, Sinewave) - model dependent
  • RMS Noise Current 7 - 35 μA at 100 kHz - model dependent

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.

DESIGNED FOR EASY INTEGRATION

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.

LASER SAFETY FEATURES

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. Long‑term reliability means better up-time, fewer service calls, and more satisfied customers.

PRACTICAL, ROBUST DESIGN

Thoughtfully designed features provide valuable benefits and protect the laser against operational anomalies.
