1.[ Components]: power component combined with peripheral precision op-amp CV and CC loop would highly improve the overall performance of module 2.[Multiple Functions]: The 900W high precise control voltage boost converter supports input voltage stability and function and constant voltage and constant current regulation function 3.[Great Memory Function]: The memory function supports storing 10 groups of parameters and can be ly stored or recalled 4.[Digital Display]: 4 Digit display could show real-time voltage, current, power and capacity, and you can select automatic or manual display in turn. There are output(OUT), constant voltage(CV), constant current(CC) indicator lights that shows real-time state Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
