Main features:
 

• In strict accordance with the industrial product design, high reliability, to adapt to all kinds of harsh conditions.
• APF can filter out harmonic 2 times to *0 times, according to the need of harmonic frequency and filter out harmonic target set separately.
• Within a very short response time, 1ms to detect harmonic change, the step of harmonic compensation completely time is less than *0ms (1/2 frequency).
• Using 3 DSP + CPLD digital control mode and speed up to *0 KHZ IGBT, closed loop control, quick, precise filter harmonic.
• Harmonics, reactive power and unbalanced load compensation model, three kinds of system working stability, affordable - *0% ~ *0% voltage fluctuation.
• With functions of automatic frequency detection, can automatically adjust to changes in the power grid impedance and system impedance.
• The three-phase unbalanced load current, APF can be programmed, eliminate the phenomenon of unbalanced load
• With soft start control circuit, to avoid too much at the moment of start into current, and limit the current to the rated range.
• APF can automatically recognize and correct CT polarity, and can correct through software, do not change the connection mode.
• Have system self-diagnosis function and powerful protection function. In line with the GB/T ******3, protection grade IP*0 (customizable)
• APF uses electric total agreement, MODBUS RTU protocol, RS**2 or RS**5 communication interface standard, can be connected to the monitoring system of communication, realize the active filter, such as remote control, telemetry and remote communication function
• 3.*-inch LCD display system, fully functional PC software monitoring, condition monitoring and control configuration, including password lock function, data measurement functions, control configuration function, real time recording function, fault recording function, condition monitoring and alarm function, support unattended.
• Electric power parameter monitoring function display: voltage, current, frequency, voltage distortion, active power, reactive power, power factor, etc.

• compensation current：*0A/*0A/**0A/**0A/**0A/**0A/**0A/**0A
• Work tolerance: voltage：**0 v (*0% ~ + *0%) ; frequency: *5hz ~ *5hz
• Filter out harmonic number：2 harmonic to *0 harmonics range can select *0 kinds of harmonic
• The degree of filtering setting：can be set separately for each harmonic
• Filtering capacity：*7%ï¼›After compensation，THDI
• Reactive power compensation：Ranging of power factor from the perceptual 0.6 to capacitive 0.6
• Active power loss：< 3%
