REOWAVE®passiveThe new generation of harmonic filters
Electrical components are continually becoming smaller, more efficient and cheaper. To achieve this, most applications include components such as thyristors or frequency converters. The components are also known as “non-linear loads“ because their characteristic curve is not a straight line, which leads to many undesirable problems. In particular, these include harmonics.
Harmonics are an example of the type of problem that are often simply not recognised correctly, but can cause significant malfunctioning – particularly with the increasing use of non-linear loads. Harmonics cause, for example, interference phenomena such as:
• Creating additional losses resulting in unnecessary consumption of energy• Reduced lifetime of transformers due to destruction of the insulation• Resonances in the supply networks• Measurement errors• Errors in tripping fuses• Serious faults in IT systems.
The solution for these problems is the REOWAVE®passive!This device is used at the place where the problems arise – where the biggest effect can be achieved. REOWAVE®passive is based on proven components of the REO CNW family such as REO mains filters and REO harmonic filters which, thanks to their excellent characteristics and the special circuit design of REOWAVE®passive, efficiently keep the harmonics away from the mains network.

REOWAVE®passive – harmonic filter with a potential for savings
REOWAVE®passive doesn’t only give protection against harmonics – significant reduction of costs is also possible. The way that REOWAVE®passive works results in reductions in current and current harmonics, enabling significantly smaller fuses, cabling and transformers to be used. REOWAVE®passive therefore enables not only energy cost savings but also savings in equipment costs.

Image 5: The design allows for the parallel connection of two REOWAVEpassive to increase the power capacity.
Image 6: Naturally several non-linear loads can be suppressed with a single REOWAVEpassive. The filter must merely be suitably rated for the required power.
Another advantage : simple integration into existing systems
In the development of the filter, REO has taken special care over simple integration into existing systems. Based on the “plug and play” idea, only the inputs and outputs of the filter need to be connected and the device will begin its cost-saving operation without problems from harmonics.
Thanks to the integral thermostat, a fan is switched on automatically as required. Another advantage of the REOWAVE®passive is the built-in mains choke. The latter ensures that only the interference in your area is suppressed, and no stray harmonics are filtered out of the mains.

REOWAVE®passive – approved REO quality
REOWAVEpassive is a filter unit which consists out of approved REO CNW components. This filter unit includes a REO mains filter and a REO harmonics filter. The mains filters function is the pre-supression of the mains as well as the shielding against external harmonics. It filters the harmonics caused by the B6 circuit (thyristor, diode bridge etc.), effects a preliminary suppression of network interference, screens the application from extraneous harmonics and enables a cost-saving in equipment selection and energy consumption.
