| LED Driver Model D-31
|
- Driver D-31 is designed for power supply of all models Mid-IR LED's manufactured by IBSG. 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 25-250 mA. One of four frequences (0.5 kHz, 2 kHz, 8 kHz and 16 kHz) can be selected.
- Pulse mode. Such mode provides maximum peak optical power from the LED. In this mode besides changing of frequency, pulse duration can be also selected in the range 0.6-20 s. Peak current in pulse mode can be changed in the range 0.25-2 A. For operation together with photoresistor PR43 should be shorter then 10 s (positions 7-9) and current not higher then 1A.
