HARMONICFILTER CNW 8981 – 60 Hz IP20

Description

Reduce Harmonics – save up to 30% energy costs.
The REOWAVE®passive filters harmonics caused by the B6 circuit (thyristor, diode bridge, etc.) and motor drives. The supply network is relieved by compensating the harmonics reactive power. This enables cost savings in material selection and energy consumption. Starting currents and current peaks are greatly attenuated.This increases the service life and reliability of electrical systems. Due to the compact and ready-build an easy installation is possible. The REOWAVE®passive helps to comply with international power quality standards IEEE 519 or EN 61000-3.

Advantages

What’s more, REOWAVE®passive can be supplied to the basic equipment as REOWAVE®passive Plus, including the following additional options:

Traffic light function
Temperature monitoring
potential-free signal contacts
Switching off of the filter function in the event of an error
Reduction of the THDI value
Increasing network stability
Reduction of the input current up to 30%
Compact design
easy integration into existing systems
higher reliability of electrical system
optionally with overcurrent indicator to check the filter effect

The options should help to better control the grid quality and issue messages to the control centre in the event of faults, meaning you have full control of your power consumption and increase operating safety at the same time.
