The RPS Series DC regulated power supplies are designed for use in laboratories, schools, and production lines, and their output voltage and output load current are continuously adjustable from 0 to nominal. It has a shutdown external circuit protection function and comes with a fixed output of 3.3V/5.0V/1A. Power supply stability and ripple factor
Both are very good and have perfect protection circuits.
This series of power supply is a linear regulated power supply with true pure copper transformer. It has high stability, minimal ripple, low noise interference, accurate and reliable, and can output at full load for a long time. It is a research institute and the laboratory recommends it first!
