Isolated DC converter pinout. Need some clarification please

Postby WV Kokamo Joe » Sun May 22, 2016 2:55 pm

I have the WRB2405CS-2W isolated power converter for the 3 digit power display. I know the Red and Black from the meter is the power in R +, Black -, Green & Blue wires connect to the laser tube wire coming from the LSPU and the other from the end of the laser tube (Cathode), Not sure which connects to what color wire. I read somewhere on here that if there is no power displaying when the laser is firing, to just reverse the blue and green wires and it should display the power.

The power converter has 6 pins, The actual labeling is 123 ** 678, 3 on each side, I found info that says Pin 1 (On the far left with the labeling facing you) is Neg 24vdc in, pin 2 is positive, pin 3 is N/C. Pin 6 is V + out, pin 7 says 0V and pin 8 is V- out

Do I connect the Red from the meter to pin 6 V+ and the Black from the meter to pin 7 or pin 8? I am assuming pins 6 and 8 for the 5vdc out to power the meter as 6 is + and 8 is -, is this correct?

I trust you have the data sheet.

Pin 1 = GND from input 24 VDC supply
Pin 2 = + from input 24 VDC supply
Pin 6 = +5 VDC to meter (RED)
Pin 7 = GND to meter (BLACK)

I didn't see that one that shows the single and dual pinout, whereas single says CS for pin 8. Don't know why they wouldn't label it Gnd.

Regardless...Thanks very much! You have answered my question! =}
