280kW Electrical Frequency Converter
GK1000 Sensorless Vector Control Variable Frequency Drive Inverter
Brand: GTAKE
Certificate: CE, RoHS
| VFDs Model | Power Rating | Input Voltage | Output FREQ | Type |
| GK1000 series | 30kW-630kW | 380V~480V, ±10% | 0.00-600.00Hz | DC/AC to AC inverters |
Advantages
Thanks to sophisticated engineers, scientific producing workmanship, rigorous quality control systems and management team, GTAKE frequency inverters are equipped with advanced features, some of which are listed as below:
01 | GK1000 consists of an active front end (AFE) and an inverter, which operate in four quadrants. The AFE and the drive are separately deployed in the cabinet, extremely convenient for operation and maintenance; |
02 | Abundant options: equipped with basic platform plus extensional function modules, achieving not only the basic function of AFE plus AC drives, but also abundant selection of dedicated functions. Numerous options are available for port expansion, function combination and system upgrade; |
03 | GK1000 AFE drives can auto adjust bus voltage, which ensures the stability of drive output current and motor rotary speed. Even if there is a big fluctuation on power supply voltage for short time, or sudden change on the load, GK1000 bus voltage self-adaption can make sure of the system operation without trip, reducing motor temperature rise and prolonging the load lifespan; |
04 | GK1000 AFE drives have quick and marvelous dynamic response to load change, no matter load is added or lessened. The drive can output suited torque simultaneously to a sharp change load; |
05 | Active Front End allows real-time regeneration of energy back into the power line. The active front end also provides power factor control for power quality management and greatly reduces unwanted power harmonics; |
06 | GK1000 are much greener than general drives since they are equipped with function of active power factor adjustment. The output current THD is less than 2.5%, no pollution to grid power supply according to standard GB14549, GB/Z 17625.6-2003; |
07 | Four control modes: V/f, SVC1, SVC2 and VC, for the purpose of fulfilling a wide variety of industrial applications with optimized control algorithm. SVC1 is the robust open-loop vector control mode accepting static auto-tune1, SVC2, the precise open-loop vector control, requires rotary auto-tune, while VC is the high performance closed-loop vector control with PG; |
