Product Overview:

20 Amp, 120 Volt OEM Laser Diode Driver Overview

The LDD-1303 is an OEM high performance current source that is primarily designed to operate in CW mode. Basic system status is visually indicated by on-board LEDs, more detailed status information can be polled at any time. The LDD-1303 can operate in a stand-alone configuration as well as in a remotely-controlled manner, with parameters adjusted on the fly. The laser diode driver is current-PID-controlled.

Equipped with optional light measurement circuitry, the LDD-1303 can also be operated as a Laser Power Controller (LPC).

Low Noise Output / Industry Leading Laser Diode Protection Features

These modules are innovative current drivers that contain a proprietary current source able to precisely drive laser diodes in pulsed or CW mode. It can be equipped with an optional laser power measurement circuit / photo-diode input. The LDD-1303 can also monitor laser diode temperature (NTC thermistor input) and includes an auxiliary thermistor input to monitor the heatsink temperature. 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.

The LDD-1303 is part of the LDD family of Meerstetter laser diode drivers, which are designed to operate alongside devices of the TEC family of Peltier controllers.

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.
