This product is a high-precision, low-noise linear constant current source designed for applications such as TDLAS gas detection systems, semiconductor laser (LD/LED) drivers, and sensor constant current excitation. Employing a linear constant current topology, it achieves output accuracy better than one-thousandth while ensuring extremely low current noise and excellent long-term stability.

Dual-mode drive, flexible adaptationIt supports multiple driving modes such as DC, DC+AC, and AC+AC, and is suitable for various constant current driving scenarios.

Ultra-high precision, better than one-thousandthOutput current accuracy is better than 0.1% (one in a thousand), and typical current fluctuation is as low as 1μA, ensuring stable laser wavelength or pure sensor excitation signal, effectively improving the system's detection signal-to-noise ratio.

Extremely low noise, linear constant currentIt adopts a linear voltage regulation and constant current architecture, which fundamentally suppresses switching noise and has extremely low output ripple, making it particularly suitable for precision optical measurement scenarios that are sensitive to power supply noise.
