SLD模块对驱动电流/电压非常敏感，在驱动电路设计上的任何错误都可能导致SLD模块的损坏或失败。在大多数情况下，模块是不能由这种损坏而修理的。为了提供一个适当水平的SLD保护，势在必行的是有一个适当设计的电路和温度控制器。Superlum公司提供PILOT驱动器容许在高水平的稳定性和保护上运转本公司生产的所有类型的冷却的SLD模块。
紧凑式底座对所有类型的模块( DIL, BUT 和 TOW)都有效。光纤耦合模块嫰够很容易地由客户在底座上替换-没有焊接要求。用TOW1和TOW2封装组建的和用TOW底座安装的自由空间输出SLD模块不能由客户更换。 专业设计的9V直流驱动控制器能够确保SLD模块有稳定的光功率输出，同时采用了多种措施以保护电流对SLD光源器件可能造成的损坏。
Pilot4-DC是经过用户大量使用的，证实的理想驱动控制器，是我们推荐的SLD模块驱动器。
特征：
• driving of all types of cooled modules of SUPERLUM,
• stabilization of SLD temperature at any value within range of +10 °C to +40 °C, with indication of the set temperature,
• stabilization of SLD direct current at any value from 0 mA to 400 mA with indication of the set current value. Higher current ranges are available on request.
• High level of SLD protection against overloading
• Low noise
Accessories:
- Mounts for modules (DIL, BUT, TOW)
- Connecting cables
- External low pass filter
Optional: remote control of SLD status and its on/off by external logic
Stability and noise
All PILOT controllers allow excellent stability of SLD modules. Typical short-term (15 min, 22±0.1 °C ambient) and long-term (3 h, 22±0,5 °C) stability of SLD modules driven by PILOTs is 500 ppm and 3000 ppm, correspondently.
No any excess noise to SLD intensity noise is added by PILOT-4 in frequency range 0,05-10 MHz; external LPF allows no excess noise starting 1 KHz frequency.
