Noker Drawer Active Harmonic Filter 3 Phase 3/4 Wire Apf Ahf For Dynamic Harmonics Compensation

Short Description:

More and more loads are non-linear, introducing harmonics into the power grid and thus significantly impairing the power quality.The drawer active harmonic filter is an ideal product effectively reduces the unwanted harmonics.

Non-linear loads, by contrast with linear loads, have become increasingly common: frequency converters in drive systems, the large numbers of switch-mode power supplies used in IT and communications equipment, and also more and more in household electronics. Even lighting technology employs mainly non-linear power supplies. Non-linear loads becomes more and more in industrial plants, office buildings, data centers or even private households.

The user can set the parameters so that the active power filter can simultaneously filter out harmonics, dynamically compensate reactive power, compensate for three phase unbalance, and compensate for voltage drop, etc.

Features

Active harmonic filter Ahf operates on the base of three-level topology circuit, provide power quality solutions such as eliminate harmonic, stepless power factor correction, and load balance. The AHF module can be rack mounted and wall mounted optional. The current from 30A to 200A. Active power filter allows 12 modules to connect in parallel, and users can easily get the target filter current capacity. It is very ideal device to eliminate harmonic wave.

Product display

The active filters adopt the hardware structure of FPGA, and the components are of high quality. Thermal simulation technology is used for thermal design of the system, and multi-layer PCB circuit board design ensures reliable isolation of high and low voltage, which provides guarantee for system safety. The apf active power filter adopts the 3-level topology, has a lower ripple in the output current and half of the output voltage transient thanks to a higher quality output voltage. This improves performance and reduces the internal filter requirement.

Application

400v active power filter can be widely used in power system, electroplating, water treatment equipment, petrochemical enterprises, large shopping malls and office buildings, precision electronics enterprises, airport/port power supply system, medical institutions and so on.
