CP Automation has teamed up with Elektrotechnishe Anlagen to sell the RevCon system in the UK. RecCon is a new product for returning to the grid the energy produced when a motor slows down, which is a more attractive proposition than 'wasting' the energy as heat in braking resistors. CP Automation expects RevCon to find applications in a number of industries including manufacturing, elevation and processing.
RevCon is claimed to work with any AC drive and is said to be much more cost-efficient than using two inverters to achieve the same effect. Furthermore, the product features a harmonic filter as part of the package, which ensures that the electricity returned to the network is fit for purpose and G5/4 compliant. A CP Automation spokesman explained that there a several prestigious projects in the UK that are already planning to install the product.
RevCon uses a feed-in tariff, similar to those used on domestic and semi commercial wind turbines, to allow the customer to charge the electricity supplier for the returned power. However, Tony Young, a director of CP Automation, explains that, while RevCon is not a similar product to a wind turbine, the analogy is useful in outlining its efficiency: "A wind turbine is not particularly effective, normally operating at about 40 per cent efficiency. In contrast, when a motor slows down and begins to generate electricity, RevCon will operate at around 90 per cent efficiency.
"However, the bottom line for most businesses is the commercial imperative, and this is where the product really comes into its own. The cost savings can be quite extensive in a facility where there are several motors controlling manufacturing equipment, lifts and the like. This is the most compelling argument to present to the board!"
As well as acting as sales agent, CP Automation also offers advice on the overall project as well as repair and maintenance on motors, inverters, resistors and other peripheral products such as encoders. The company also provides replacement equipment when repair is impractical or not possible. In these instances, CP Automation's independence comes to the fore, allowing it to stock a range of products from all the major motor and inverter manufacturers. Indeed, replacement inverters, encoders and motors are normally installed in a matter of days.
