Technical detail about product Datasheet
The LDTC2/2 includes both a Laser Diode Driver and a Temperature Controller that each drive up to 2.2 A. The LDTC 2/2 E includes the chassis enclosure. The LDTC 2/2 O includes only the open frame electronics. For 500 mA laser diode current, the LDTC0520 is available. For 1 A laser diode current, the LDTC1020 is available. Integrated controls make this a plug-and-play module. Add only a power supply, laser diode, thermoelectric and sensor, and heatsinking. All cable sets are included.

The temperature controller is compatible with thermistors or linear temperature sensors such as the LM335 or AD590. Adjust temperature using onboard trimpot or a remote voltage input. This voltage input has added default protection for when a D/A remote setpoint is turned off, unplugged or goes down and it automatically sets the temperature to control near ambient. Default is 25°C for a 10 kΩ thermistor (1 V). Adjustable trimpots configure heat and cool limits.

The laser diode driver maintains precision laser diode current (Constant Current mode) or stable photodiode current (Constant Power mode) using electronics compatible with A/B Type lasers. The LDTC2/2 delays and slowly ramps the current for maximum protection. Onboard trimpots set current limit and setpoint. Alternately, you can switch to remote inputs for the laser driver current setpoint. Use either the onboard Enable/Disable switch or a remote input. An LED indicates status of the laser diode output current. Switches select Constant Current or Constant Power mode.

Ideal for integrated laser driver or LED packages that include temperature control, often used in medical diagnostics equipment, remote sensing, analytical instrumentation, military and communications applications.

NOTE: Customization to 3 A laser diode output current using the WLD3343-3A is available.
