MICROTEST 7120 power meter standby power consumption tester7110 is used in environmental monitors, energy-saving lamps, exchange power supplies, transformers, uninterruptible power systems, power tools, 3C electronic products, household appliances, etc

The input current peak factor of MICROTEST Power Meter 7110/7120 can reach CF3/CF9, and it has excellent energy measurement characteristics for all data within the range. It also has the same level of power meter in terms of automatic file changing speedfastIt can quickly lock the current range and accurately analyze power consumption, with a measurement range from 0.001W to 16KW for average energy measurement. MICROTEST 7110/7120 energy measurement contains AC power consumption with DC component. For analyzing the current signal of asymmetric electrical appliances with positive and negative half cycles, the power factor PF obtained is more accurate. In response to the EU's standby specifications for electrical appliances, manufacturers are committed to reducing standby power consumption as much as possible and can help electrical appliance manufacturersrefinedAnalyze the standby power consumption of our own product and be able to perform long-term power consumption analysis with a personal computer.
