DetailsUltimaker 2 Hot End Heater - 50 Watts! This is more powerful than the default heater of 25 Watts (35W on machines since around Jan 1, 2016).
This is not an Ultimaker standard part. It is made by a different supplier.
For tinkerers only - you will have to modify your PID settings (cutting all 3 values in half because of the double wattage would in theory be the correct PID values to use).
