2025 Controller

Buyer is responsible to understand and properly wire according system requirements.

The diagram below is for a 24V Electrathon, and provided for refernce only. For use with other applications, a contactor may be required in addition to the main powe switc shown.

For use with 36V and higher, install an appropriate pre-charge resistor across the main pwer switch as specified by the manufacturer:
     36V=250 Ohm, 10Watt
     48V=450Ohm, 10Watt
     72V=1000Ohm, 10Watt

  • To protect the controller from reverse polarity, also place a diode in-line with the 12V 2A fuse shown.
  • For added safety, wire a micro switch that is OPEN (when throttle lever is in the OFF position) in-line with the 12V 2A fuse shown. This switch is often standard on pot-box throttle input assemblies.
  • For added safety, place an additional (small) interlock/ignition switch or key-switch in-line with the 12V 2A fuse shown.
