Kyoritsu 3128 high-voltage insulation tester
08 July, 2009The Kyoritsu 3128 high-voltage insulation tester has a variable test voltage of up to 12 kV at 35 TΩ, with a short-circuit current of 5 mA. In addition to insulation resistance testing, the tester offers a range of diagnostic insulation testing.
Cost of installed solar photovoltaic systems drops significantly
13 March, 2009According to a US survey, the cost to deploy solar energy systems has reduced significantly over the past decade, paving the way for more market acceptance of this alternative energy source.
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.
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.
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.
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.
Wire wound resistors
01 August, 2008The Merlin Power Resistor range is available in a wide range of resistances and wattages from 20 to 2000+.
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.
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 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%.
