Use the WLD33ND-2AEV Evaluation Board to rapidly prototype a complete laser diode control system using the cutting edge technology of the WLD33ND Laser Diode Driver. Onboard switches, connectors, and trimpots make configuration and operation simple. Input and output cables are also included. For lower noise operation use the WLD33ND-2L. For lower voltage operation compatible with Li-Ion batteries, the WLD33ND-HB can be used. This evaluation board does not include the controller. Adjust laser diode forward current (Constant Current Mode) or monitor photodiode current (Constant Power Mode) using the 12-turn onboard current setpoint trimpot. Laser Diode current range (200 mA or 2 A) and Photodiode current range (200 µA or 2 mA) are configurable. It works with A, B, and C type laser diodes. A trimpot configures the laser diode forward current limit. A switch sets mode as either Constant Current or Constant Power. Power it through the terminal strip or using the 2.5 mm circular connector and the PWRPAK-5V, PWRPAK-7V, PWRPAK-9V, or PWRPAK-12V power supplies. The input cable set allows easy connection to your power supply and monitoring equipment while the output cable set quickly connects to your laser diode and monitor photodiode. High power applications can use the onboard fan connector to power a WXC303 or WXC304 (+5 V or +12 V DC fan) attached to a WHS302 heatsink. The LDMOUNT-5A, a 14-pin butterfly laser diode mount with integrated heat sinking, is available for simple connections between the WLD3393 and the laser. This driver board is widely used in electro-optic qualification, spectrometers, medical diagnostic equipment, range finders, and on research benches. Free, effective, and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard product can be easily modified to meet your application requirements.
