SDR-240 DIN rail power supplies
03 February, 2009The SDR-240 is the first model in the Meanwell Slim DIN rail product series of DIN rail power supplies. The slim design of 63.5 mm in width saves space on the rail and makes it 42% smaller in size in comparison to its predecessor model.
Harmonic filtering solutions for VSDs
03 February, 2009NHP’s Advanced Active Front End/Regenerative VSD solutions produce a very low level of harmonic distortion in addition to providing benefits for managing regenerative energy back into the mains power grid.
DC to AC inverter
02 February, 2009The Matrix modular DC to AC inverter is an integrated inverter power system designed for applications where high reliability backup AC supply is required.
Active power filter
02 February, 2009The SPC smart power conditioner from PQ Tech is an active harmonic filter series suitable for single-phase sub-distribution circuits in commercial buildings, shopping and entertainment centres and small industrial enterprises.
Energy-efficient UPS
02 February, 2009The Powerware 9130 series of UPS is designed to help users carry out green initiatives in IT environments. The 700-3000 VA UPS models are available in rack and tower formats and feature a high-efficiency design that is claimed to save energy without sacrificing reliability.
Line reactors for power systems
01 December, 2008The Practical Control Solutions line reactors are designed to attenuate harmonic distortion by impeding unwanted harmonic current resulting from the switching techniques used in many of these devices, which reflect unwanted harmonics back into the mains, often interfering with other equipment and causing excessively high neutral currents.
Power disturbance monitoring relay
01 December, 2008The PQube DIN rail-mountable power and disturbance monitoring relay captures voltage disturbances and time-stamped waveforms, storing captured information on a plug-in 4 GB SD card that provides exportable CSV Excel-compatible and GIF picture files via ethernet with email, DHCP, FTP and SNTP options.
Backup power
01 August, 2008The PB256 power supply has battery backup applications in industrial, telecoms, security and access control markets. The units, connected to a lead acid battery, are built to provide uninterrupted power to a DC load in the event of a mains failure.
Wire wound resistors
01 August, 2008The Merlin Power Resistor range is available in a wide range of resistances and wattages from 20 to 2000+.
Major projects to meet future power demand
11 July, 2008Major projects have begun to meet the growing need for power in south-east Queensland, according to Mines and Energy Minister, Geoff Wilson.
Power management for UPS
01 July, 2008The Network UPS Tools power management software has been included in the Opengear range of console servers, adding to its overall power management offering for data centres and remote branch offices.
Power condition assessment
01 July, 2008Delta3000 is an automated insulation power factor test set to non-destructively assess the condition of high-voltage electrical equipment such as transformers, circuit breakers and motors, and measuring the excitation current and inductance of transformer windings
Power quantity monitor
01 July, 2008The Power Standards Laboratory PQube power quantity monitor measures voltage disturbances and steady-state trend values and stores the data on an SD card.
UPS battery management
01 July, 2008The RiBat battery management system is designed to extend the life of UPS batteries used in IT infrastructure, with a claimed service life improvement of up to 30%.
Harmonic filters
01 July, 2008The ECOsine FN3410/3412 series of three-phase harmonics filters is the latest generation of Schaffner broadband passive harmonics filters to enable better utilisation of the power capacity of distribution transformers and networks, thereby increasing efficiency to either allow more nonlinear load to be connected to the same system or postpone expensive upgrades to the electrical system capacity.
