Formula Editor, Device Settings and Fast Analog Outputs Core losses at small cos cp and high frequencies if(P>l) bell();fi J>l^— INormall Local I1* gal (with optional 500kHz precision band- width and delay compensation to 4ns) The magnetizing current I flowing in the primary winding is fed into the current input of the LMG95, and the induced volt- age at the open secondary winding is fed into the voltage input. In this way, only the core losses (magnetizing losses) are measured, and not the copper losses. The half-wave rectified voltage value, also measured with the LMG95, is a measure of...

Energy Efciency EuP - Energy using Products The directive 2005/32/EC denes ecodesign requirements for household appliances and ofce machines. It regulates the admissible energy consumption while a product is in use as well as the energy consumption during its fabrication and its disposal. In addition, the directive addresses further ecological aspects like saving resources through an economic material usage and avoiding hazardous substances. Green IT To save the environment, information technology and communications equipment has to economize on energy and resources throughout its life...

Energy Efciency The LMG95 meets these high-end requirements. LMG95 To optimize the scaling and to protect the unit, use an additional external shunt (L95-SH-xxx-P). For low currents, use the wiring for current-correct measurement. (See also into our application note #102 “Measurement of Standby Power and Energy Efciency”.) The ZES ZIMMER software CE-Test-Standby in combination with a precision power meter LMG95 or LMG500 measures the standby consumption according to the standard IEC/EN 62301. CE-Test-Standby congures and monitors the measuring devices, sets the test sequence and generates a...
