the universal driver for leds d-31m

驅動d-31m提供了兩種運行模式：

ü準連續波(qcw) (準穩態)模式。在這種模式下，電流可以在25ma到250ma之間進行調節。其中有四個頻率可以選擇(0.5 khz, 2 khz, 8 khz and 16 khz)。

脈沖模式：在這種模式下，除了頻率可以改變以外，脈沖寬度也可以在0.6-20μs范圍內進行選擇。峰值電流在脈沖模式下可以在0-2a范圍內進行調節。

特性

driver d-31m provides two modes of operation:
¤quasi continuous wave (qcw)(quasi steady-state) mode:
this mode provides maximumaverage optical powerfrom the led. current 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:this mode provides maximumpeak optical powerfrom the led. in this mode in addition to adjusting of frequency, pulse duration can be also selected in the range 0.6-20 μs. peak current can be changed in the range 0-2 a. please, don't use combination of frequency and pulse duration that gives duty cycle >10%. we recommend using 2 a pulse current only at pulse duration <1 μs.
