SPS101 Quad-channel adjustable power supply
Koheron SPS101 is a 25 W power supply with 4 adjustable outputs (3 positive and 1 negative rails). It operates from a single 18 V to 33 V input supply. Integrated input and output EMI filters ensure low levels of ripple and radiated emissions (< 10 mVpp). The SPS101 allows powering different modules from a single power supply.
