Description : <br>  <br> Electric Energy Saving Power Meter Watt Consumption Monitor Analyzer  Features :   1. Measure real-time voltage of the power supply (90~150V AC or 160~280V AC); 2. Measure real-time operation power of the appliances (0~3000W); 3. Show the power consumption (0~9999kWh); 4. Calculate the cost of energy according to the pre-set price of energy (0~$9999); price of energy can be pre-set to the local price by users; Two ways for calculating power consumption and power cost : electricity consumption and electricity cost in single operation period and accumulated electricity consumption and electricity cost in all operation periods; can be manually cleared to 0. 5. Operation condition monitor : The indicator light will flicker when the real-time ratio of operation condition reaches its alarm point. Ratio of operation condition is the ratio between accumulated operation time per hour (running power is over preset standby power) and 1 hour. Alarm point for ratio of operation condition and standby power can be pre-set. 6. Show the operation time of appliances (0~24h~9999d) Two ways for calculating operation time : time in single operation period and accumulated time in all operation periods; can be manually cleared into 0.  Specification :   Plug style : 220V EU\/ 230V AU\/ 110V US\/ 230V UK plug for option~  1. Voltage : 90~150V AC， 60Hz or 160~280V AC， 50Hz; 2. Peak load : 15A 3. Temperature : -10~60 4.
