Scottish Water has replaced the ageing DC pump drive motors of three large sludge pumps at one of its wastewater facilities with matched W21 high-efficiency AC motors and CFW-09 drives from WEG. The DC motors were employed on Whitehead and Poole piston ram pumps that are used to transfer sludge from the Laighpark wastewater treatment site, which serves around 150,000 people in the Paisley area of Glasgow, to Shieldhall wastewater treatment plant. They had been installed for some years, providing the high torque at start-up necessary for the pumping operation, and the facility for variable speed control of the pumps via a simple potentiometer. Because the capacity for storing sludge at Laighpark is limited, transfers to Shieldhall are made daily. This places a premium on the reliability of the two front-line motors - the third is a duty stand-by - which are generally called upon to operate for six hours a day. This was not a problem until recently, when the age of the motors starting...

With its price, its flexibility and a power range of up to 20 Hp, the Lenze AC Tech SMVector drive excels in environments where inverter technology was once considered too costly, including packaging machinery, food processing machinery, material handling/conveying systems and HVAC systems. The Lenze AC Tech SMVector Inverter carries all the features required by demanding applications including four modes of operation (V/Hz, Enhanced V/Hz, Vector Speed, and Torque), high starting torque, auto-tuning, advanced low-speed control, and dynamic speed regulation. The Lenze AC Tech SMVector Drives continue our price leadership tradition in the highly competitive AC drive market. The Lenze Group's SMVector VFD delivers on its promise of price leadership while delivering unparalleled performance and simplicity. The SMVector is the right choice when you need it all. Program the SMVector quickly and easily using the electronic programming module (EPM). The EPM stores the AC Tech drives p...

TURCK's New M12 Eurofast AC/DC Junction Box contains an integrated DC power supply that allows the use of DC sensors in AC applications. This unique 4-port junction box simulates a 2-wire AC sensor providing a cost-effective solution that is easier than installing a separate power supply and relays. Costs are reduced by using DC sensors, which are generally less expensive, instead of AC sensors. The newly integrated power supply also permits the end user to utilize the more prevalent and varied DC sensors in every application, and reduces sensor stock levels. The AC/DC Interlink BT Junction Box offers 85-132 VAC input, 100 mA output per port, and 24 VDC output to PNP short-circuit protected sensors only. The die-cast aluminum alloy, fully encapsulated housing offers IP 67 protection when all ports are connected or are covered with closure caps. A 7-pin minifast ® connector provides home run quick connection.
