Product Overview:

LDD-1303-VC1 High Performance Laser Diode Driver

The LDD-1303-VC1 is a high performance current source which offers high compliance voltage for high voltage pumps (ie 808, 915, 940, 980nm) and laser diodes connected in series. It is a precision current source designed to bias laser diodes in continuous wave applications. Its power converter topology allows for an output voltage smaller, equal, or larger than the input voltage. This enables the LDD-1303-VC1 to efficiently drive laser diodes with up to 120V compliance voltage from a single 48V power supply. The LDD-1303 offers multiple laser diode safety features, including two inputs for laser diode temperature monitoring, current limits and a soft start current ramp. The device can be fully digitally controlled, the firmware is upgradeable and various digital communications interfaces are available. A 0 - 10V analog Input as well as a 0 - 10V analog output are integrated. Additionally, laser diode power control feedback is available by using an external photodiode is possible using the on-board amplifier.

The LDD-1303 has been developed as a CW Laser diode driver but can also be used as a pulsed driver (350 µs). In series even higher output voltages can be achieved. The LDD-1303 is fully digitally controlled; the firmware is upgradeable to offer various communication options and to meet specific customer requirements.

USB and RS485 Interfaces with Control Software

Configuration parameters further include: control source selection, maximum current limits, nominal current ramping, PID controller settings, NTC temperature sensor modeling coefficients, measurement circuitry calibration, error thresholds, etc. The LDD-1303 is configured over an industry-standard RS485 or a USB connection, either GUI-driven using the included LDD Service Software, or by direct parameter control using the predefined communication protocol.

The included PC-Software (USB / RS485) facilitates configuration, control, and real-time monitoring of the LDD-1303. All device settings are saved in non-volatile memory and can be backed up and restored.

Recommended Power Supply

This power supply is one that is recommended to use with the LDD-1303: Mean Well RSP-2400-48. Other suitable models are available; please inquire for more suggestions.
