Near Intersection of I-35 & I-90 Southern Mn. | I agree. Ag Leader introduced a high current PWM driver at the recent Dealer Meeting. I don't know if it is available yet. This driver is installed in between the Liquid module and the 12V device.
This driver or an equivalent is used when the device needs more current than the module can provide directly. The driver uses a direct connection to the battery to provide the current that is actually used to run the device.
In theory this arrangement should work with up to 10 sections as has been mentioned. One consideration is whether the pump can handle what might be a rather wide range of flow rates. One should check the maximum and minimum flow rates (gallons/minute) that the system would need to handle. This will also help in the decision of the proper flowmeter to use.
The maximum would be with all sections ON, maximum ground speed and applied rate. The minimum would be with only one section ON, minimum ground speed and applied rate.
