Profile: Shenzhen Powtran Technology Co., Ltd. is a manufacturer and supplier of variable frequency drives. Our products include inverters & converters, soft starters, servo drives & motors, EMI filters and spare parts. Our inverters & converters feature novel structure design, optimized production technique and mature test equipment. These are widely applied in electronics, metallurgy, mining, petrochemical, transportation, building materials, municipal, metal processing, paper making, injection machine, central air conditioning, and numerical control machine tool. Our PI7800 family inverter supplies the more comprehensive motor control solution. It employs the advanced technology of PWM control & vector control, high performance power module and DSP control. It is with internal current loop to realize high precision of close loop control and reach the stability & precision of current & frequency. Our soft starters are applied in motor drives of larger KW. It adapts 16 single chip Micyoco digital automation control. The mode of connection is three input and six output. It can provide motor slip start progress and reduce the starting current on the impact of power grid. It also reduces vibration and noise of equipment & extend the life span of mechanical transmission & improve the working environment for artificial. It has different kinds of protection such as over current, over load and line input phase loss to ensure the safety of equipment & motor. We export our products to various countries worldwide.
