► REO-USA introduces next generation of current transducers for all industrial applications

August 25th, 2016


After developing highly successful technology used specifically for railway engineering, REO-USA is now introducing a new generation of closed loop current transducers.

The WKO-2C series is designed for use in all industrial applications and assures improved current measurement accuracy of better than 0.5% in the whole frequency range of DC to 120 kHz. It can be used in various applications such as variable frequency drives, servo motor drives, uninterruptable power supplies, and all types of switched mode power supplies and power supplies for welding applications, to name a few.

WKO-2C frequency response

REO-USA's frequency response in the +/- 0.5% range with double core technology compares favorably to a competitor's higher range.


"What we learned from our first series was implemented to develop the WKO-2C series for a wide range of applications. Our patented double core technology is a tremendous benefit. It has outstanding accuracy and frequency response and is more affordable than what was initially developed in the WKO-2C-B series," remarked Alex Ward, Technical Sales Engineer for REO-USA. "Similar technology is available in the marketplace, but none offers higher accuracy than our double core technology."

► REOHM Braking Resistors find acceptance with high protection and outstanding benefits

June 15th, 2016


With an optimal structure and power consumption to withstand vibration and shock tests and other advantages, air- and liquid-cooled REOHM Braking resistors from REO-USA are proving to be a solid choice for a variety of companies throughout North America, especially those with aggressive environments.

Braking resistors BW 155 and BW D 330 from REO-USA

Liquid-cooled and air-cooled REOHM Braking resistors from REO-USA offer high protection.




Used for braking or load resistor for drive technology, industrial applications and railway engineering, REOHM Braking resistors are available with power levels from 50W to 60 kW, and even greater with a modular installation. The liquid cooling method is proving to be very efficient for drawing heat away from a heat source, allowing for the spatial separation of the electricity and liquid carrying lines to ensure safe application.

There are many other benefits beginning with a unique design says Alex Ward, Technical Sales Engineer for REO-USA.

"Our customers have the choice of modular construction for higher power levels or a compact design, which allows for a very dynamic space savings," informed Ward. "Our Braking resistors offer a variety of cooling options and high protection with a rating up to IP67. This allows it to be used at higher ambient temperatures and in more aggressive environments."
