Electric Vehicle Power Take-off Step-Down Box (IEC C13 Connector)

My electric bike used to be 48v, and I bought a water pump that was also 48v. Now the electric bike has been replaced with a 72v one, so I made a step-down box to convert it to 48v. This way, the water pump can continue to be used, otherwise high voltage would burn it out

Theoretically, converting a 60v electric bike to 48v is also possible, and 72v to 60v is also possible. As long as it's a step-down conversion, this circuit board can be used. This circuit board is adjustable

This circuit board is nominally rated for 600w, my water pump is nominally rated for 300w, and it worked fine in actual testing

Required:

1 circuit board (approx 25 RMB on PDD);

1 AC01 socket (2.5 RMB on PDD);

1 figure-eight power cord (like those for rice cookers or monitors; if the electric bike interface is the new national standard, a new national standard cable or adapter will be needed)

8 heat-set inserts (M3*H3*OD5);

8 M3 nuts
