Active Power Filter

Active Power Filter We are looking for experienced Distributors and Agents worldwide! General introduction It adopts the most advanced analog logic method to eliminate harmonic. Real-time detect the wave form of the non-line loads in the grid. Active harmonic filtering, power factor improvement all in one, excellent quality, wth the characters of quick response, widely filtering, high efficiency filtering, won't affected by the parameter of the system and it is small in size. Working principle Real-time detect the load current, quick distinguish the harmonic current component and fundamental wave, input equal and opposite compensate current into the grid to realize instant filtering and power factor improvement. The passive current provided by ZAPF could be preact or hysteretic, in order to improve the grid power factor and realize power factor improvement. Main Characteristics Optimal double-closed loop control and filtering control technique adopted to ensure accurate sensing of harmonic and efficient filtering; Boasted dynamic quick response, wide-scale harmonic filtering; Well-developed portection system and intelligent control methods within the equipment can automatically limit current in response to the temperature to assure stable long-term operation of the device. Due to this, the resonance with user's power network system can be avoided to achieve safe work of the user's equipment. Harmonic and power factor improvement strategy applied optimizes the user's power factor imporvement technology. Unique control calculation ensures perfect combination of the two devices. LCD screen applied onthe operation interface, easy for handling;Display interface can show the voltage, current, harmonic and some other parameters; Optional function includs the harmonic filtering mode, power factor improvement mode and the combination of harmonic filtering and power factor improvement mode; Polarity and change rate of current transformer can be controlledthrough software; Target power factor and output current can be controlled to meet the demands; Device failure and unexpected errors can also be recorded. Simple design and scheme selection, easy for installment and operation, flexible cable arraangement (from the top and from the bottom); if special transformer is adopted, it is suitable for 10kv or below.
