| LED Driver and Temperature Controller Model DLT-27
|
- Driver DLT-27 is designed for power supply of all models Mid-IR LED's with built-in thermocoolers. Driver provides two modes of operation:
- Quasi Continuous Wave (quasi steady-state) mode. Such mode provides maximum average optical power from the LED. Current in this mode can be changed in the range 20-250 mA. Frequence of modulation is 16 kHz.
- Pulse mode. Such mode provides maximum peak optical power from the LED. Peak current in pulse mode can be changed in the range 0-2 A. Pulse duration is 1 µs
- Temperature controller that is built in DLT-27 provides selecting and stabilizing of the temperature on LED's chip in wide range. That gives possibility to tune wavelength or optical power.
- Frequency can be changed accordingly the customer's request.
Also at the using of photoresistor of PR43 model the pulse duration must be changed to 10 µs.
