3. Description

High-stability light source requires high-stability driver. The stability of the driving current determines the stability of the light source. The BLP-PCS-650 uses deep negative feedback technology to provide ultra-low current ripple. Each is small and easy to use with supply voltage of 5V. All products are specified for operation from –20°C to +125°C
