Product Description

Product Profile

VTF880-RFcan be used as both a rectifier and an inverter, operating in four quadrant mode. Adopting IGBTand SPWMmode, it

can control the size and phase of ACpower, and make the ACinput wave close to sine wave through various filtering and energy

storage links in the front end. The power factor is adjustable positive and negative with a midpoint of 1. When the braking energy on

the motor side returns through the inverter, the DCbus voltage increases, It can make the phase of the ACinput wave opposite to

the power supply voltage, achieve regenerative power generation operation, and feed back the regenerative energy to the AC power

grid to meet the control requirements of high-performance inverters.

Product Features

 

PWM control method, current harmonics<5% (GB/T14549-1993);
The DC bus voltage remains stable;
By controlling the phase difference angle between voltage and current, the power factor can be adjusted between -1~+1;
Chinese 7-inch touch screen display, calculus measurement and feedback of power grid energy;
Higher reliability, with protection against overvoltage, undervoltage, overcurrent, short circuit, and lock
