4-40v to 1.25-37v 74w 2a LM2596:




This is a simple and inexpensive low powered buck regulator based on the LM2596 regulator IC. Voltage is
adjusted by a heli-pot on the top, and displays current or voltage on the onboard segmented LED display. Press
the TAC button to toggle between displaying output voltage and current. Include two SMD LEDs to indicate
input and output power, and a reverse polarity dummy diode on the input. Hard to beat the price, 2 for $10
shipped. I keep a few of these on-hand to handle unanticipated needs.
