380V Active Power Filter (APF): 25A/35A

Specifications

380V Active Power Filter:

Applicable to three-phase three-wire and three-phase four-wire system.

Applications:

In the fields of architecture, medical treatment,communication, factory and others, there are many types of nonlinear loads such as UPS, transducer,charger,office equipment,lamp,elevator and air-conditioner, etc.,they produce a large amount of harmonic waves in the running process and result in serious pollution to the power distribution system and even interrupt the control system and cause production breakdown or growth of defective products.

Working Priniple:

Our 380V Active Power Filter provides real-time monitor to the load current through the external current mutual inductor, and pick up the harmonic wave of the load current via the internal DSP,and then send to IGBT by PWM to control the inverter to produce a harmonic current that has the same current and reverse direction with the load current,which shall be delivered into the electric net.

Characteristics:

1. Able to filiter 2 to 50 times of harmonic wave or in specified times at one time

2. Response time < 300us

3. Three compensation modes: harmonic wave,reactive and unbalance

Significant advantage:

1. Small Size, wall-mounting and rack-mounting save the most space for user

2. 3DSP+CPLD control mode with strong calculation

3. Work efficiency is higher than 97%, low consumption

4. Modular design,applicable to all kinds of work conditions, realize N+1 redundancy

5. 3.8" LCD monitoring system, PC enhanced software

6. Application cases in diversified industries,applicable to various complicated nonlinear systems.
