Specifications

Details

Integrated controls make the LDTC1020 a plug-and-play module. Monitor signals are brought out on one cable. Onboard trimpots set current limits and operating setpoints. Remote inputs are provided for both laser driver current setpoint and temperature setpoint. Onboard switches set laser diode current Enable/Disable and select Constant Current or Constant Power mode. The unit is 2.4x2.9x1.1 inches.

The LDTC1020 protects against brownouts and slowly ramps the current for maximum protection. The temperature controller has added default protection in case a D/A remote setpoint is lost, automatically setting control near ambient. Default is 25°C for a 10 kΩ thermistor (1 V).

The robust module has been integrated into demanding applications such as military, spectroscopy, and biosciences.
