(S), unit of electrical . In the case of (DC), the conductance in siemens is the reciprocal of the in (S = per ); in the case of (AC), it is the reciprocal of the in ohms. A former term for the reciprocal of the is the mho (ohm spelled backward). It is disputed whether the siemens was named after the German-born engineer-inventor (1823–83) or his brother, the electrical engineer (1816–92). direct currentRead Moreresistance (electronics)Read MoreohmRead More Site ExplorerClose site explorer DC Protective Unit and ControllerSitras PRO for DC traction power supplyNEW YORK/FRANKFURT Siemens AG (SIEGn.DE) has approached Emerson Electric Co (EMR.N) to explore buying the network power business that the U.S. factory automation equipment maker is looking to shed for as much as $4 billion, people familiar with the matter said.Emerson said last June it planned to spin off the power business to concentrate on its industrial automation operations as well as its commercial and residential heating and air conditioning divisions.

Emerson's network power business provides equipment and services that stop mission-critical systems from failing, including surge prevention, uninterruptible power supplies and precision cooling. Its main customers are operators of data centres and telecoms networks and energy providers and its main rivals are Eaton (ETN.N) and Schneider Electric (SCHN.PA). Siemens could combine the business with its power-distribution activities.Emerson, also exploring options for the rest of its non-core businesses, is talking with private equity firms, including Platinum Equity LLC, about a sale, the people said, which would be simpler and less risky than a spin-off. Other companies have also expressed interest, according to the people.There is no certainty over which course of action Emerson will pursue and no deal is likely until later this year, the people said, asking not to be identified because the negotiations are confidential. Siemens, Emerson and Platinum Equity declined to comment.A price of $4 billion would imply an enterprise value of 0.9 times 2015 sales and 18 times EBIT (earnings before interest and tax), capital goods analysts at Barclays said, almost twice the EV/EBIT multiple of Emerson as a whole.

The Barclays analysts said Siemens would be able to combine some of its products with Emerson's but they also said: "We struggle to see at this stage how the company could materially improve the growth and margin profile of this business."Rain Head Shower HeadsBarclays rates Siemens "equal weight".

Siemens trades at 2015 EV/EBIT of 15.0, Eaton at 12.5 and Schneider Electric at 11.4. The remaining non-core businesses that Emerson has been looking to sell include its motors and drives, power generation and remaining storage businesses.Collectively, these assets generate around $200 million in annual earnings before interest, tax, depreciation and amortisation, sources have previously told Reuters. St. Louis, Missouri-based Emerson has seen its earnings hit by a strong dollar and a drop in oil prices, which have curtailed spending by customers. Rivals, such as General Electric Co (GE.N) and Rockwell Automation Inc (ROK.N), have also been hit by weak oil prices.Siemens' healthcare, transportation and energy-management businesses have benefited from a weak euro and cost cuts.

Traction & Rolling Stock, Passenger, InnoTrans Siemens to unveil Mireo modular EMU concept SIEMENS: Proposals for a new family of modular articulated electric multiple-units for commuter and regional services will be unveiled by Siemens at InnoTrans 2016. The Mireo is intended as a successor to the Desiro Main Line family which has been supplied to SNCB (305 trainsets), Austrian Federal Railways (101), GySEV (5) and MittelrheinBahn (17). It is aimed at a similar market to the Stadler Flirt (1 200 sold), Alstom Coradia Continental, Bombardier Talent 2 (445) and CAF Civity. Mireo EMUs would feature welded bodies formed from extruded aluminium profiles, with attention paid to aerodynamics. The driving cars would be 26 m long and intermediate cars 19 m long, with units of two to seven cars envisaged. Options would be available to suit platform heights of 960, 760 or 560 mm. The bogies would be based on the inside-framed design used on the Desiro City, with the end bogies having a wheelbase of 2 200 mm and the intermediate bogies 2 600 mm. Wheel diameter would be 860 mm, with an axleload of up to 20 tonnes.

AC units would have one high-efficiency transformer-rectifier, with a roof-mounted 750 V DC link to the inverters. Both end bogies would be powered, with a varying number of intermediate bogies powered according to the operator’s requirements. Siemens envisages three options: Eco giving an acceleration rate of 0·65 m/s², Midi with 1 m/s² and Speedy 1·2 m/s². The maximum speed would be 140 or 160 km/h.Railway Gazette is the official international media partner for InnoTrans 2016, which will be held at the Messe Berlin exhibition centre from September 20 to 23 2016.
