2 Ways, 3A Step Down DC-DC Regulator
This 2 Ways, 3A Step Down DC-DC Regulator is manufactured by Sure Electronics and designed for heavy duty use. It is a low-cost, high-reliable, heavy duty load DC-DC converter. Both ways could generate 3A continuous output and work stably. Output voltage could be selected from 3.3/5/9/12/15 by encode switches, and could be well adjusted through multiturn potentiometers. If in need, just change some resistor values, and you could get other output value.
All regulators are 100% tested in full load condition, the burning time in test lasts for over 12 hours in several conditions.
All test results are from real measurement, and all diagrams are printed directly from DSO’ screen capture, we promise that all such snaps are reliable and trusty.
DC Output Range could be selected by encode switch. All regulators pass full load burn-in test.
