What is a power meter?

Power meters measure key parameters of electrical power consumption in residential and commercial buildings, energy systems, manufacturing, and charging infr... This is a scalable design for powering the AMD Xilinx Zynq UltraScale+ MPSoC family (ZU2 to ZU19).

What are the problems with smart meter power supplies?

Designers of power supplies for smart meters are faced with a range of issues. Not only do they need to take account of typical concerns such as energy efficiency, but also issues such as fraud and correct operation if the electrical supply fails. The ability to run from low power levels is important.

Do smart meters have to have a grid power source?

Only smart electricity meters have the luxury to have a grid power source and, even in this case, consumption must be minimized as the power to run the devices comes from the utility and not from the customer. Gas and water meters on the other hand need to be able to run from a battery, and guarantee a lifetime of ten years or more.

What are smart utility meters?

Although smart utility meters have stringent demands, solutions exist to deal with problems such as tampering, and provide tolerance to power failures so that the meter can at least signal to the utility firm that it has encountered a problem and needs maintenance.

Why is it important to have a smart electricity meter?

The ability to run from low power levels is important. Only smart electricity meters have the luxury to have a grid power source and, even in this case, consumption must be minimized as the power to run the devices comes from the utility and not from the customer.

What is a 5V meter?

The device operates over a wide 2.2 V to 5 V input-voltage range and incorporates a very-low quiescent current, always-on power supply, a 500 mA buck/boost converter, a 150 mA low dropout regulator, and eight power-distribution switches to provide a high degree of power control to meter electronics.
