APF Series Harmonic Suppression Drawer Type Wall Hanging Active Power Filters
Application
Active power filter (APF) adopted modern power electronic
technology, is a new power harmonic treatment equipment on basis of
hi-speed DSP, digital signal processing technology. It consists of
instructive current calculation circuit and compensated current
production circuit. The instructive current calculation circuit
monitor the current of the line at real time, and convert analog
current signal to digital signal, transmitted into DSP, and
processed, separate the harmonic waves from basic content, send
driving pulse to compensated current production circuit via PWM
signal, drive IGBT or IPM power module, produce a compensated
current with same amplitude of the harmonic wave, but reverse
polarity, to eliminate the harmonic waves in the system.
APF active power filter is an ideal product for the enterprise that
need high electric quality or its power system is heavily distorted
and need improved, it can be used widely in steel metallurgy,
communication field, rail transportation, tobacco, medical field,
water treatment system, cement filed, automobile field, program
control field, papermaking field, solar energy field, printing
field, building field and etc. The product has steady quality, good
performance, meanwhile it can save energy, save material, which is
a new way to solve the harmonic waves of the current.

Rated capacity | 50A | 75A | 100A | 150A | 200A | 250A | 300A | 500A |
Rated voltage | AC380V±15%/690V±15% | |||||||
Electrical wiring | Three phases and three lines, three phases and four lines | |||||||
Rated working frequency | 50Hz±5% | |||||||
Filter range | 2-50 harmonics (selectively filtered, each harmonic compensation can be set separately) | |||||||
Level of filtering | Each harmonic is selected for an amplitude compensation setting | |||||||
Automatic flow limit output function | When the harmonic function current to the load side is greater than the device current, the device limits the output current to the rated value | |||||||
Overtemperature protection | The radiator temperature above 65℃ starts the fan automatically | |||||||
No-voltage protection | The system voltage below the Un85%, main circuit breaker will lose voltage protection and the device stops working | |||||||
In line with overflow protection | The current flowing through the load exceeds the threshold, and the device stops working | |||||||
Compensation for overflow protection | The equipment has two protection of software and hardware, software protection point (peak current) can be set by itself, generally can be set as 2 times the rated current (RMS) and hardware protection point is 2.3 times the rated current (RMS). When the compensation current exceeds the protection threshold, the equipment is stopped and reported to the corresponding guarantee | |||||||
System voltage protection | The system side voltage underthreshold or overvoltage threshold and the device stops working | |||||||
DC voltage protection | The equipment has two protection of software and hardware, software protection point (peak current) can be set by itself, generally can be set to 1.1 times the normal voltage and hardware protection point is 1.3 times the normal voltage. When the DC voltage exceeds the protection threshold, the equipment is stopped and reported to the corresponding guarantee | |||||||
IGBT protect | The internal temperature of IGBT exceeds 108℃, the unit stops working and reports the IGBT fault | |||||||
Impact current; | Double the IGBT rated current in the power module | |||||||
Filter energy | 95% | |||||||
Filter effect | Comply with the GB/T 14549-93 assurance requirements | |||||||
Compensation mode | 1, Supplementary harmonic, and the harmonic times are optional | |||||||
2,Reharmonic and reactive, some models are available | ||||||||
Overload capacity | 120% | |||||||
