Rackmount power supply
16 October, 2009 byThe Mean Well HRP-75 series is a 75 W AC/DC enclosed power supply, designed to provide energy savings through features such as low ‘no-load’ energy consumption, built-in active PFC function (PF >0.9), high operating efficiency and built-in remote ‘on/off’ control.
DC power rectifier
15 October, 2009 byThe eSure DC power rectifier is designed to be used to power electronic equipment in the telecommunications industry, delivering a claimed 97% energy efficiency, meaning far less energy is wasted in the conversion from AC to DC power. Less wasted energy results in an equivalent reduction of generated heat, which results in lower cooling requirements and reduced infrastructure costs.
DC-DC converters
25 September, 2009The Vicor DC-DC 28 VDC input family has been expanded with the addition of eight wide-input Micro DC-DC converters.
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.
Power factor correction capacitor banks
02 September, 2009 byPower factor correction capacitor banks from Janitza Electronics are suitable for LV three-phase power distribution. They are supplied with detuning chokes, discharge resistors, internal busbar system and HRC fusegear.
Three-phase uninterruptible power supply
02 September, 2009 byThe MGE Galaxy 3500 is a three-phase general-purpose uninterruptible power supply (UPS) designed for applications in the 10-40 kVA segment – from small electrical rooms up to demanding industrial environments.
Energy-storing capacitors
02 September, 2009 byThe WIMA SuperCap double-layer capacitors are now available as cascaded and balanced modules with capacitances up to 200 F or with nominal voltages up to 28 VDC, for use in applications such as slip control of large wind power plants, starting micro-turbines, fuel cell start-up, starting large V16 or V24 cylinder motors in train or naval drives, energy storage in conjunction with photovoltaic devices, recuperation of braking energy for automobiles and parallel connection to batteries in vehicles or other applications.
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.
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.
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.
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.
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.
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.
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.
