690V Active Power Filter: 25/35A

690V Active Power Filter:

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

Applications:

Produce 30-180A compensation current, applicable to the nonlinear load in 690V voltage level power distribution system.

In consideration that some power distribution systems in the fields of coal, petrochemical, metallurgy and harbor adopt 690V voltage level. our 690V active wave filter realizes harmonic wave control to the nonlinear load. those industries use a lot of large power transducers, intermediate frequency furnaces, rolling machines and DC speed regulators, which have serious pollution to the power grid.q.

Characteristics:

1. Passive wave filter compensates the reactive and filters the lower harmonic waves, other harmonic waves shall be filtered by active power filter.

2. Solve the problems that passive filter is easy to suffer power impedance and easy to have resonance with the system, work principle: show low impedance status to a certain frequency harmonic current, filter the harmonic wave that has fixed times, bad flexbility, big volume and low utilization.Active power filiter can filter 2~50times of harmonic wave and ave real-time response to realize dynamic filtering.

3. Mixed type filter may exert their own advantages to make the device with big capacity, low cost and good performance.

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.
