FG1290 импульсный источник интегрированная энергетическая Efficienc

As one of the biggest power energy consumers in telecommunications devices, switching power supply always is a very chief object in energy-saving and emission-reduction. The key energy efficient indexes of switching power supply include System efficiency, input power factor and input current harmonics. Traditional instrument can test input power factor and input current harmonics but cant provide System efficiency directly. Traditionally we have to record the results from more than one instrument and get a uncertain result through a complicated calculation. In addition, because the load of switching power supply is dynamic changing anytime, apparently this traditional method is impossible to get an synchronous and accurate result. We recommend a brand-new revolutionary tester---- FG1290 Switching Power Integrated Energy Efficiency Analyzer, this instrument can solve the below question perfectly. It can show basic electric parameters like voltage, current, power and importantly it can offer all the 3 key energy efficient index of switching power supply: System efficiency, input power factor and input current harmonics. It can test DC input power and AC input active power synchronously through simply operation and get scientific and accurate results. So its definitely a necessary instrument in energy-saving and emission-reduction.features:The first instrument can directly read the energy efficiency indexes without complicated operation.Multi-functional:DC, single-phase,3-phase AC test
