VMA Electrostatic system
The micronised particles of the treatment liquid, due to their electrostatic charge, are attracted to the vegetation causing the atomised liquid to cover the leaves COMPLETELY thereby extending the benefits further. This is why the combination of low volume with the electrostatic system signifies a veritable quantum leap in treatments on a global scale.
The electrostatic generator for atomizers VMA consists of a single sheet made of modern technology, in order to ensure maximum reliability. The sheet is sealed to allow high operating tensions in reduced spaces. The circuit consists of a generator that brings the output voltage to 18kV. The circuit is equipped with the following hardware protections: • reverse power polarity: you can reverse polarity without damaging the card. • resettable electronic fuse. Overvoltage arrester on the input voltage, in case of excessive battery voltage intervenes by protecting the electronic card failures. If excessive ambient temperatures the card is disabled preventing failures. The operation is guaranteed at high temperatures (50 ° C environment).
HOW DOES IT WORK
The circuit is composed of an intermediate voltage booster generator connected to a voltage multiplier that brings the output voltage to 18kV. The electrostatic system, connected to suitable electrodes placed in the vicinity of the nozzles, generates a positive electric field able to induce a negative charge in the air that exits from the atomizer. The ions are then attracted to the electrode but before they can reach it they are incorporated in the treatment flow by switching to it the electrical charge. Because the vegetation often has a natural positive charge, albeit weak, due, for example, by the presence of potassium cations, the liquid is attracted towards the negatively charged vegetative wall greatly reducing the effect of the drift and thereby saving the plant protection product to be used.
The flow of air also has the task of avoiding that the jet of water and the electrode are never in contact. In any case a safety device included in the system warns the cases of short-circuit and immediately interrupts the the power supply to the electrodes in order to avoid any damage, then automatically turn on after a few seconds.
• Input voltage in operation from 9V to 18V • Automatic shut-off for voltages out of range (<9V or> 18V) • Limit voltage 35V • Overtemperature protection: shut-off for temperatures over a maximum settable limit • Over-current protection with resettable electronic fuse • Rated circuit output voltage: 18kV • Duty point at maximum output power: 12kV-800uA • Continue Electronic Limitation beyond this value in order to limit the output current under 800uA • Approximatedimensions: 125x125x35mm
• Place the control panel of the electrostatic charging system in the cab of the tractor • Make sure the system power switch is OFF • Connect the appropriate power plug to the user in charge of the tractor
