Canworld designed CDE500Y series special frequency converter for the application of oil field boring machines and tower pumping units. Treating for motor energy feedback without braking unit and energy feedback devices. In China, there is no other company to produce this special inverter. And CDE500Y avoids overvoltage and smooth operation during working, saving investment costs and energy saving.
＞Using energy loops and power loops to achieve smooth control of the bus voltage, to avoid the over-voltage of the inverter caused by the motor's power generation in the reciprocating operation of the boring machine
＞Without braking units and braking resistors, saving costs and energy
＞Can set the punching time
＞Drop slowly and rise fastly: drop slowly can pump more oil; rise fastly can improve efficiency
＞Can achieve constant power operation, optimize the oil field pumping process, and achieve energy savings
＞Supports remote 3G/GPRS wireless network communication to achieve networked, intelligent and centralized control of all work units in the oil field
＞Perfect protection: input phase loss; output phase loss; phase-to-phase short circuit; ground short circuit; moisture-proof design
