XCD-H7000 series is a high protection special frequency converter for water pump, which is mainly used in equipment occasions that require automatic constant pressure function (such as fans, water pumps, etc.). Its body protection level reaches IP65 and is suitable for various harsh working conditions. After the related equipment is equipped with this series of inverters and set the required pressure. If the pressure exceeds the set value, the inverter will start to decelerate to make the pressure is constant within the set range. The inverter will control the air compressor or water pump motor to automatically adjust the speed, the equipment used can achieve the best energy-saving effect under the condition of basically unchanged pressure. If it runs at the set pressure value for a long time, it will automatically stop, and it will also automatically start when the pressure is lower than the set lower limit threshold, which simplifies human operation.
