Puls Power Supply Has Three Micro Controllers Puls has launched its latest Q-series unit, a 40A, three-phase power supply. The QT 40 measures 110 x 124 x 127mm and weighs 1.5kg Two versions of the QT 40 are available - 24V 40A and 48V 20A - both delivering 960W with efficiency of 95.3 per cent. The QT 40 uses three micro controllers to maintain optimum efficiency at all levels of load. This also makes power sharing easy by allowing multiple units to be mounted side by side on the DIN rail without the need for fan cooling. Other features include near-zero inrush at switch-on, shut-down input with high Mean Time Between Failure (MTBF) values and built-in mains fuses. Puls' Bonus Power overload design provides 150 per cent current reserves for up to 4sec to help start demanding loads. The QT 40 is suitable for industrial bulk-power applications, such as control systems for large electric motors powering production equipment, conveyors and machine tools. It is also suitable for o...

Hitek Power Supply Offers 0-70kV Output Voltage Hitek Power has added an RS232-controlled variant to its XRG70 series of compact, high-voltage power supplies for high-performance analytical and measurement X-ray applications. The XRG70-703 RS232 offers an output-voltage range of 0 to 70kV at 0 to 1mA and maximum output power of 70W. The unit also incorporates a 5.5V DC, 3.5A grounded-filament power supply, part of of Hitek 's range of products designed for use in grounded-cathode applications. The filament supply is automatically controlled by the integral beam-current loop control and the power stage uses a current-fed resonant push-pull converter to give high efficiency while ensuring reliable operation. The product combines surface-mount technology, high-voltage stress control and new packaging techniques. It measures 140 (W) x 73 (H) x 233mm (D) and weighs 3.3kg. The RS232 interface offers remote monitoring of output voltage and current, filament voltage and current, volt...

GPEG And 4D Systems To Supply 'Smart OLED' Modules GPEG International has announced its partnership with 4D Systems, which will provide customers with 'Smart OLED' modules. These passive- and active-matrix OLED display modules feature a built-in embedded graphics controller that ensures feature-rich functionality that can be simply and effectively incorporated into new product designs. All 4D Systems's 'Smart OLEDs' feature: a near-360-degree viewing angle; high contrast with resolutions up to QVGA (320x240); a five-pin interface to any host device (5V, TX, RX and GND) and reset; a supply voltage from 3.6V to 6.0V; serial RS-232 (0V to 3.3V) with an auto-baud feature (300K to 128K baud); an optional USB interface via the 4D Systems micro USB (uUSB-MB5) modules; an onboard micro-SD (uSD) memory card adaptor included for storing icons, images and animations; three selectable font sizes (5x7, 8x8 and 8x12) for ASCII characters and user-defined bitmapped cha...

Stahl Releases Fieldbus Power Supply System Stahl has expanded the ISbus range, adding a modular Fieldbus power supply system that provides up to 28V and 500mA for Foundation Fieldbus H1 segments, and allows for redundant supply. In Boost mode, a parallel connection of two power supplies enables users to continuously supply the bus with up to 1A, providing sufficient power reserves even for special Fieldbus applications. An integrated basic diagnosis function monitors each segment for line faults, reporting these via a potential-free relay contact and indicating them via a red Error LED. The activation of the integrated switchable Fieldbus terminator is clearly indicated by a yellow LED. The units can be installed on a DIN rail or clicked into place on special bus carriers. On each bus carrier, up to eight segments with a standard supply or four segments with a redundant supply are connected to a host via optional precon-figured system cables. The bus carrier can be operated with...

Steelplanner Optimises Duferco's Supply Chain Duferco La Louviere has implemented two Steelplanner modules for the optimisation of its supply chain, complementing the existing Steelplanner environment. The first additional module is Betamatcher Midterm for the optimal Hot Strip Mill coffin selection. To efficiently manage a HSM, a planning department must tackle two complex and consecutive problems: the assignment of slabs to orders and the scheduling of those assigned slabs. Traditionally, these two logistical problems are solved independently. However, this way of working has many drawbacks. This may result in assigned slab-populations that are not feasible to schedule or that result in poor schedule-quality. The implementation of Betamatcher at Duferco La Louviere has resolved these issues. It has solved the assignment problem and the HSM-scheduling critical constraints in one optimisation round. Mr Tufaru, planning manager at Duferco, said: 'Betamatcher Midterm added...
