Intrinsically safe power supply
02 September, 2009 byThe RN221N combined active barrier and power supply is SIL2 rated and provides galvanic isolation for the 4 to 20 mA measured signal. It is suitable for use in hazardous areas and can be powered by 20 to 250 VAC/DC, reducing the need for different versions across the plant.
DIN-rail power supplies
02 September, 2009 byThe PBAMR product family is a Class II output DIN-rail switching power supply that is suited to building and factory automation applications and electromechanical and marine-related installations with medium to high power demand.
Branch circuit power meter
02 September, 2009 byPowerLogic Branch Circuit Power Meter (BCPM) is a high-accuracy, full-featured meter designed for the multi-circuit and minimal space requirements of a distribution board or a high-performance power distribution unit (PDU). In data centres, for example, the meter helps plan and optimise the critical power infrastructure to meet the demands of continuous availability.
Janitza DIN-rail power quality analyser
02 September, 2009The Janitza DIN-rail mounting, UMG 511 power quality analyser is capable of providing 24/7 continuous monitoring and analysis of single- and three-phase, three- and four-wire networks.
PRO-M switchmode power supplies
02 September, 2009The PRO-M range of switchmode power supplies provides a claimed 50% space saving over regular power supplies and no ventilation gap required between multiple units, enabling them to be installed into tight locations within switchboards or machines.
Transformer analyser
09 July, 2009 byThe Serveron continuous, online, dissolved gas analysis monitor for transformers is available in two models, both based on closed-loop gas chromatography.
High-density power hub
09 July, 2009 byThe FieldConnex 500 mA high-density power hub is an addition to the FieldConnex fieldbus interface products, designed for fast installation and reliable long-term operation in a fieldbus infrastructure.
Protective relay testing
09 July, 2009 byTo enable electrical installations and relays to be tested to the new IEC 61850 international communication standard for electricity substations, an IEC 61850 option has been introduced for the MPRT protective relay test system, together with MGC configurator software.
Energy storage batteries
09 July, 2009 byThe SEC TSG range of 12 V sealed lead acid batteries deploys Monobloc Catalyst technology for long-life operation, thereby combining the safety and low-maintenance advantages of sealed lead acid batteries with the long life of normal lead acid batteries.
Strain gauge signal conditioner
09 July, 2009 byThe ACT20P-Bridge strain gauge signal conditioner and isolator provides four switch-selectable input ranges of 0 to ±10, 20, 30 and 50 mV and proportional analog output of between 0-22 mA with loads of <600 Ω, and 0-11 V with loads >1 kΩ. Accuracy is claimed as being better than 0.05%, with a temperature drift of better that 50 ppm over the range of -40 to +70 °C.
Low harmonic drives
09 July, 2009 byThe VLT low harmonic drive eliminates the harmonic disturbances on the supply grid by actively imposing currents into the grid so that the high-quality sine wave of the grid current is restored.
