1 2017 High Quality Choice and Better Power Managment to Help Smart Meter Monitor Your Household Energy Usage

2 What Is Smart Meter? Smart meter is a new type digital power meter It can record power usage information and on-time report to electric power company, so that electric power company can adjust power line delivery. User can understand each household appliances energy consumption and condition by internet and control system, and further adjust electricity consumption or power saving to reach green power or energy saving. HOW YOUR SMART METER HELPS YOUR POWER BILL Your smart meter measures and records electricity usage every 30 minutes. Data is transmitted to electricity distributors, who own and manage the grid, poles and wires. You can monitor your household energy usage, to help compare offers and better manage cost. Energy providers make consumption data available to you, via web portal or in-home display. Source : Victorian Energy Saver,

3 Smart Meter AC to DC Controller Power Function High reliability and efficiency, and more cost-effective for circuit design selection PAJIT is a global discrete supplier and manufacturer, while the HV MOSFET can support V (V DS ) and 2-4A (I DS ) with TO-252 and TO-220 package. Snubber diode and VCC rectifier are packaged by SMAS package, which offer 1000V/1A specification; whereas the secondary section we provide low VF schottky diode packaged by TO-277B. PAJIT can offer integrated product category and meet the switching-mode power supply design needs.
