It drives my pump well with 4-20 mA pressure sensor. However, would be nice if it could throw an error if a sensor is disconnected. Otherwise it can damage equipment it is attached to. As a workaround I'm going to apply energy to the inverter trough a mechanical pressure sensor which will discharge the device if pressure is above the maximum threshold.
It's home and the merchandise is not complete,, Mr. "Seller. I regret that there is no communication with you until after 6 days when the goods were in Slovakia at the Customs office. This was the fact that workers from the AliExpresu had to advance the withdrawal period for the delivery of the goods in order not to have a problem. I ask you to send the English manual in book form as it should be along with the product! I ask you for a reply with yours John
