de Haardt EV Shutdown Transponder

Every Electric kart to be controlled remotely must be equipped with an Xtra.EV Shutdown Transponder. Assembly is quite simple thanks to the V-shaped bottom which fits perfectly on both round and square frame tubes. Controlling may be done through individual kart, group of karts or all karts together. These numbers can be assigned by track operators using the Xtra.Remote Control. Multiple tracks can be controlled fully independently. Split tracks may be (re)combined to one single track with a few clicks on the Xtra.Remote Control.

The Xtra.EV Shutdown transponder is fully configurable by the user and therefore can work with a wide range of motor controllers. Thanks to the high efficiency electronics, the input voltage lies in the range of 10…95V. This exceptional range makes the Xtra.EV Shutdown transponder operate on electric karts using up to 6 series batteries of 12V. During charging of the batteries the Xtra.EV Shutdown transponder can be LOCKED. During the LOCK the Xtra.EV Shutdown transponder does not respond anymore to speed commands coming from the Xtra.Remote Control. This gives extra safety during charging.

The total battery voltage can be read out in real time using of the Xtra.Remote Control.
