► Introducing remote CP monitoring and adjustment from REO-USA: REOTRON SMP power supplies

September 17th, 2015

One person, one location, and one REO-USA REOTRON SMP-CP series DC power supplies unit for use with cathodic protection devices. That's all it takes to monitor corrosion prevention along an entire pipeline, or throughout refinery piping and storage, in water treatment facilities, bridge infrastructure - any industry that requires cathodic protection. All monitoring is done remotely.

REOTRON SMP-CP for use in cathodic protection applications
While remote CP monitoring and adjustment eliminates time and labor, operational efficiency is enhanced by low ripple (+/- 100mV) with REO-USA's REOTRON SMP-CP series power supplies. Output power options: 500W or 1000W. The SMP-CP/M is a plug-in model.



The same person can then also adjust CP current flow, if and as needed. Remotely. No need to send someone out to measure CP at every device, every 4-6 weeks. No need to manually adjust rectifiers. Centrally located REO-USA REOTRON primary switched power supplies render such routines obsolete.

"Time and labor savings can be huge," says Charlie Presley, Technical Sales Engineer for Indianapolis-based REO-USA. "Service organizations can simply focus on periodic system maintenance that may be needed every six months, instead of spending time on CP at six - week intervals or even more often."

Next-generation REO-USA technology

"This truly is next-generation technology versus old-school rectifiers and labor-intensive efforts," Presley continues. He notes that various companies produce sensing equipment that can measure the potential for corrosion in a structure. They send that signal to the REOTRON SMP supply via Internet link, satellite communication systems or other interface options built into REO-USA SMP units.

► REO-USA introduces a new generation of 5-limb chokes

July 8th, 2015

REO-USA has introduced its new generation of CNW 910 and CNW MC 835 series of 5-limb chokes, offered with or without water-cooling the devices can be either used as three-phase network chokes or motor chokes, and in the standard version are dimensional for nominal currents up to 1,200 amperes.

In addition to huge savings in weight and volume - up to 40% and combined with low thermal heating - due to their special 5-limb body they are indispensable to the electromagnetic compatibility (EMC) of the entire system.

The new generation of 5-limb chokes from REO-USA offers a host of outstanding benefits.

"When using regenerative converters, chokes are generally employed to provide clean, sine wave-shaped power. Depending on the type of converter, common-mode interference can occur, creating additional thermal loading on the choke," remarked Rick Jones, Senior Director of Engineering for REO-USA.

"Similar problems occur with motor chokes generally known to allow longer motor supply lines and designed to protect the motor and its insulation. In both cases, magnetic fields lying outside the core can seriously affect components located in the vicinity of the choke."

Jones said an additional unwound limb ensures the choke are able to both transmit and damp common-mode noise until such time as it can be ultimately conducted to earth. The new generation of REO-USA chokes not only provides an effective solution to these problems, but also demonstrates low levels of noise emission. Space-saving design and reduced manufacturing costs make the new chokes even more cost-effective.
