[NJARC] 5A Buck Converter 4-40V with Display - use for Filament or detector supply

[Jim Whartenby]

I see your $12.95 and raise you $6.49 with free shipping!  eBay item # 222790259448 and it measures either input or output E&I or output I&P!  Sneaky little bugger, isn't it?
   
   - Function Description:
   - Module has IN / OUT, ON / OFF two buttons: IN / OUT button to switch the input voltage and output voltage display, long press to switch the output current output power display; ON / OFF button control output ON or OFF, long press Set power on default output status is ON or OFF.
   - CC is the current setting potentiometer, clockwise rotation, can increase the set current, when the load current reaches the set current, enter the constant current state, CC constant current indicator (red) lights up; the right CV is the voltage setting Potentiometer, clockwise rotation, can increase the output voltage. ON indicator is the output status indicator, when the output voltage is on, otherwise off.


Jim I wonder why people argue over the 10% of their differences and ignore the 90% they agree on?
