WPC Powebox Question


Recommended Posts

What is the Thermistor value for a WPC powerbox?

 

NTC 5D-11 is listed at Johns arcade MOV/NTC kit.

https://www.johns-arcade.com/product-page/mov-ntc

 

However the part number in WPC-95 schematic 5016-12978-00 indicates an 8amp 2.5 ohm R25 type (CL-030).

Which would be closer to NTC 3D-20

Is the cold resistance of 2.5 ohm a bit low and 5 ohm cold resistance a more desirable (less) current on power up?

 

5d-11 tend to get hot, I think its rated at 4 amps max so it could be running on the brink

 

I would recommend 5d-15, I think about 6 amps

This seller posts reasonably fast
