Teseq, a developer and provider of instrumentation and systems for EMC emission and immunity testing, introduces a new line impedance stabilization network (LISN) for conducted emissions testing of grid connected power conditioners (GCPC). The DC-LISN-M2-25-V1 is designed for measuring unsymmetrical disturbances on DC power ports in the frequency range from 150 kHz to 30 MHz.
Research results have shown that a typical artificial mains V-network as described in CISPR 16-1-2 cannot be used for the assessment of unsymmetrical disturbances of a photovoltaic inverter's DC port. CDNs based on IEC/EN 61000-4-6 are typical not specified for high common-mode currents and differential mode disturbances. Additionally, they are undefined below 150 kHz.
As a leading company in the ventilation and fan equipment market, Addvent has expanded its range to comply with the recent changes to the Building Regulations.
The Approved Documents Part L & Part F, as well as stating minimum air flow requirements now needs minimum energy efficiencies, with fans meeting a minimum Specific Fan Power (SFP). This is measured in watts per litre a second (W/l/s) of airflow extracted and all models in the new Part L & Part F range comply.
In today's modern world the uninterrupted use of data communications is taken for granted. Lightning discharges resulting in induced surges and over-voltages can cause major problems to computer equipment resulting in physical damage, data loss and corruption and the associated misery of down time and lost production.
Due to the success of the 2010 ladder campaign, Engex- in association with participating CEF branches, are campaign partners in the HSE's Ladder Exchange Initiative 2011.
The Ethos 4255 Isolation Kit comes complete with an Ethos 4162 - voltage / continuity tester. This tester has some fantastic features; firstly the unique auto-spring back sleeves which ensure that the tester remains as a GS 38 tester (no more losing the push on plastic caps) in addition to a built in torch for dimly lit areas.
To compliment the very successful range of fluorescent emergency lighting, Lightsafe has launched a new range of LED Emergency Lighting.
