LDxCHA Laser Diode Drivers

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.

3A Temp Controller for 0,062" PCB HTC3000-62
The advanced and reliable circuitry of the HTC series achieves 0.0009°C temperature stability. Its small, low profile package is ideal for designs with space constraints. The linear, PI control loop offers maximum stability while the bipolar current source has been designed for higher efficiency.The HTC temperature controllers are easily configured for any design. Virtually any type of temperature sensor can be used with the HTC and a built in sensor bias current source simplifies use with resistive temperature sensors. The independently adjustable Proportional Gain (P) and Integrator Time Constant (I) can be modified to optimize temperature overshoot and stability.Other features offer added flexibility. A single resistor sets the maximum output current to your load. Add a diode to operate resistive heaters with a unipolar output current. An onboard reference voltage simplifies potentiometer control of the temperature setpoint. You can also choose to operate remotely with an external setpoint voltage. Two monitor pins provide access to the temperature setpoint voltage and the actual sensor voltage. Key Features Compact Size - 1.5 and 3.0 A Models Interfaces with Thermistors, IC Sensors, & RTDs Single supply operation +5 V to +12 VDC (contact factory for higher voltage operation) +11 V compliance with +12 V input Stabilities as low as 0.0009°C Temperature Setpoint, Output Current Limit, Sensor Bias, Proportional Gain, and Integrator Time Constant are User Adjustable Monitor outputs for Temperature Setpoint and Actual Temperature Linear Bipolar or Unipolar Output operates thermoelectrics or resistive heaters
