The universal driver for LEDs D-31M

驱动D-31M提供了两种运行模式：

ü 准连续波(qCW) (准稳态)模式。在这种模式下，电流可以在25mA到250mA之间进行调节。其中有四个频率可以选择(0.5 kHz, 2 kHz, 8 kHz and 16 kHz)。

脉冲模式：在这种模式下，除了频率可以改变以外，脉冲宽度也可以在0.6-20µs范围内进行选择。峰值电流在脉冲模式下可以在0-2A范围内进行调节。

特性

• §驱动D-31M提供了两种运行模式:准连续波模式(使LED取得*大平均光学功率)和脉冲模式(使LED获得*大峰值光学功率)。
• §可调的电流幅值，重复率和脉冲宽度，用于选择适合LED的*佳模式。
• §和选择的放大器或其它设备保持同步。
• §易用、耐用

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.
