WEEDit runs on a standard 12 volt system. Power is connected directly to the battery that runs to the interface box. The interface box does many tasks, one of them is to invert 12 volts up to 30 volts. A low voltage system suffers high power loss over large distances, so to overcome this WEEDit inverts 12 volts to higher voltage levels so that power loss across large 36m booms is minimized.
This inversion allows higher voltages to be used but most importantly allows the interface box to send a very high signal voltage to that specific solenoid for fast opening times. These solenoids are able to open in 1 millisecond and close in 5 milliseconds. At 25km/h the ‘delay distance’ to open the solenoid is only 8mm!
The ‘smarts’ inside the interface box send a high ‘opening voltage’ so that the solenoid opens quickly, but then the voltage is lowered to a ‘holding voltage’ should the solenoid need to remain open for longer bursts.
Be aware that some competitor systems require additional boxes to be installed to act as “boosters” to handle large distances, and these come at an extra cost to you.
