20 Amp, 45 Volt OEM Laser Diode Driver Overview

The LDD-1301 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-1301 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-1301 can also be operated as a Laser Power Controller (LPC). Inquire for details and ordering information.

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 CW mode. The driver board can be equipped with an optional laser power measurement circuit / photo-diode input. The LDD-1301 includes an input to monitor laser diode temperature (NTC thermistor input) and includes an auxiliary thermistor input to monitor the heat sink temperature. The LDD-1301 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-1301 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-1301 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.
