Power Supply Monitor Manages DC/DC Converters

Image
Linear Technology has introduced the LTC2978 power supply monitor and controller for digital management of up to eight 0-6V power supplies. Configuring multiple DC/DC converters in an already complex system can be a complicated design task when using passive components. Values defined by external trim resistors and capacitors such as start-up time, set point value or switching frequency make a system inflexible. To alleviate these issues, digital control over analogue power suppliers has allowed for quick adjustment of output voltages and precise protection, monitoring and diagnostic mechanisms. The LTC2978's PMBus-compliant interface provides easy access to an on-board EEPROM, giving users supply configuration, fault response and logging capabilities. In addition, an array of supervising, margining and sequencing functions make the LTC2978 an all-in-one digital power management solution, simplifying the design challenges and reducing the component count typical of traditional ana...

Nexans To Supply Cable Link For Desalination Plant

Image
Nexans is to supply a high-voltage underground cable link that will power an Australian seawater desalination plant, which is currently under construction in the state of Victoria. The contract covers the supply of around 260km of 220kV XLPE cable, made and tested as a 275kV cable, to Thiess Degremont, which is contracted to design and construct the EUR2.2bn (GBP2bn) Victorian Desalination Project to deliver up to 150 billion litres of water a year to Melbourne and regional communities. The Victorian Desalination Project includes an 84km underground pipeline to connect the reverse-osmosis plant to a transfer main and then back to the reservoir. The electric power required by the new plant will be supplied by the 87km-long underground cables co-located with the pipeline, creating the world's longest high-voltage AC underground link operating at this power level. An underground link was the preferred option for the project since it is both more energy efficient and secure than overh...

Airsaver Unit Automatically Controls Air Supply

Image
The Airsaver control unit developed by Beckair is a compressed air control device designed to switch off the air supply when it is not needed. Any waste of compressed air is eliminated, which lowers energy consumption and cost. It has timed functions that combine to give 'supply on demand' operation. The air supply stops when a gap occurs in the containers on a conveyor or when a container stops in front of the sensor. The stop signal can be delayed to allow the last container to pass through a machine by means of an adjustable timer. The Airsaver can be used with a variety of sensors. Startup is instantaneous once a moving object is sensed again. One Airsaver unit can operate up to three valves. The sensor unit operates from a 24V DC supply and a power supply can be provided with options for both 110V and 230V AC. Payback time is typically within two to three months of use. It can be mounted onto existing installations and is protected to IP65, so it can be used in most envir...

Pressure Regulators Ensure Constant Gas Supply

Image
Dome-loaded 797 LE-HD gas-controlled pressure regulators from Witt can provide an economic and safe solution to ensure gas cutting systems receive a constant gas supply, according to the manufacturer. The company said this system of gas regulation is more economical than using a full electronic control system. In one application the three inlet lines for oxygen and propane are supplied via Witt pressure regulators to optimise the automatic gas supply. The gas control was regulated using proportional valves with changes in the gas pressure being adjusted by pressure changes, thereby controlling the cutting process. Witt pressure regulators can be used for numerous applications with a range of flow rates and gases. They are used as a primary pressure regulator, which can be installed in any orientation, in gas supply pipeline systems to ensure a consistent stable pressure up to a flow of 2300m3/h and are independent of any inlet pressure fluctuations in the gas supplies, including gas w...

SolaHD IP67 Rated Power Supplies Eliminate Need for Enclosures in Extreme Industrial Environments

With the increasing demand for machine device control and communication over industrial Ethernet, DeviceNet, and other networks, OEMs have found that installing traditional power supplies in distributed and remote locations has become prohibitively complex and costly because of the need for protective enclosures, fans, and excess wiring. In addition, enclosures introduce another potential point of failure into the production line. To reduce cost and complications, SolaHD has launched its new IP67 SCP-X self-sealed power supplies. They mount directly on machines or as freestanding components on a production line, removing the constraints imposed by power supplies that must be housed in enclosures. Compared to power supplies housed in a separate enclosure, the IP67 SCP-X reduces total cost of ownership by as much as 54 percent. Because the IP67 SCP-X is available in 100 watt and dual 100 watt models, it has the versatility to power from one to four loads. The 100 watt model has a s...
