SLD模塊對驅(qū)動電流/電壓非常敏感，在驅(qū)動電路設計上的任何錯誤都可能導致SLD模塊的損壞或失敗。在大多數(shù)情況下，模塊是不能由這種損壞而修理的。為了提供一個適當水平的SLD保護，勢在必行的是有一個適當設計的電路和溫度控制器。Superlum公司提供PILOT驅(qū)動器容許在高水平的穩(wěn)定性和保護上運轉(zhuǎn)本公司生產(chǎn)的所有類型的冷卻的SLD模塊。
緊湊式底座對所有類型的模塊( DIL, BUT 和 TOW)都有效。光纖耦合模塊嫰夠很容易地由客戶在底座上替換-沒有焊接要求。用TOW1和TOW2封裝組建的和用TOW底座安裝的自由空間輸出SLD模塊不能由客戶更換。 專業(yè)設計的9V直流驅(qū)動控制器能夠確保SLD模塊有穩(wěn)定的光功率輸出，同時采用了多種措施以保護電流對SLD光源器件可能造成的損壞。
Pilot4-DC是經(jīng)過用戶大量使用的，證實的理想驅(qū)動控制器，是我們推薦的SLD模塊驅(qū)動器。
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.
