The basic parameters of the product series: AC690 + series inverter supply voltage: Low Power Phase: Three-phase Brand: Parker PARKER output voltage regulation mode: high carrier frequency PWM control filter: filter built Rated voltage: Three-phase AC380-500 V Rated current : 0-400 A Rated Capacity: 0-315 kVA applicable motor power: 2.2 kw Details Product Overview: AC690 + series AC drives in a single series, is designed to meet all the needs of frequency applications, including simple single motor speed control to advanced multi-drive systems. AC690 + is the core of the motor-driven model based on advanced 32-bit microprocessor, which provides an excellent platform for dynamic performance, increase a variety of communications and control options, you can adjust the drive to meet your demanding needs. AC690 + offers 380-500V three-phase 0.75kW to 900kW and 220V-240V 0.75 - 45kW, including single-phase input 0.75 - 2.2kW. Product parameters: open-loop (V / F) for controlling the mode for basic motor speed control or parallel control. Quick Setup menu and full-character display and start troubleshooting to ensure quick and easy. Sensorless vector control through sophisticated MRAS (model reference adaptation system) provides high starting torque and fast speed regulation. Through continuous motor model, MRAS provides accurate speed simulation (without any speed measuring device). Closed-loop vector control AC690 + plus encoder feedback option, enabling closed-loop flux vector performance. 100% full load static torque and high dynamic response speed loop (bandwidth up to 45Hz). Meet the needs of the vast majority of the number of applications. For applications that require regeneration line 4-quadrant operation or frequent braking capacity, AC690 + series offers AFE unit to replace the dynamic braking resistor to achieve efficient use of energy. AFE allows safe and effective regenerative power returned to the grid, to achieve unity power factor. AC690 + AFE can also meet the needs of low harmonics. Parker AFE provides total solutions package, including LCL filters and other required components
