OEM/ODM Manufacturer Frequency Transformer 50hz To 60hz - High-performance Frequency Inverter for Water Pump LSD-H7000 – LINGSHIDA

Product Introduction

LSD-H7000 series frequency inverter is a special water pump inverter, mainly used in equipment occasions that require automatic constant pressure function (such as fans, pumps, etc.). After the related equipment is equipped with this series of inverters and the required pressure is set. If the pressure exceeds the set value, the inverter will start to decelerate. When 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 automatically start when the pressure is lower than the set lower limit threshold, which simplifies human operation to the greatest extent and saves worry and effort.

Product Application

According to the current working status of the air compressor and water pump, if the pressure reaches the preset value, the motor will run after unloading, which will generate unnecessary electricity demand and waste electric energy. After installing the frequency converter, and setting the required pressure, if the pressure exceeds the set value, the frequency converter starts to decelerate, to make the pressure be constant within the set range. The frequency converter controls the air compressor or water pump motor to automatically adjust the speed, so that the equipment used can achieve the best energy-saving effect under the condition that the pressure is basically unchanged. If it runs at the set pressure value for a long time, it will automatically stop. And when the pressure is lower than the set lower limit threshold, it will automatically start.

Product Technical Features
