Low-cost, smart and secure meters for green energy
With a growing demand for power and energy, local utilities and consumers are requiring a more efficient way to monitor the energy consumed. Green smart meters help to improve awareness of this energy consumption while using very little power themselves. This solution provides the components for a low-cost, smart and secure green meter. This tamper proof and connected system gives users the ability to view information about their power consumption via remote data acquisition and transfer.
Benefits
- Magnetic tamper proof to protect data
- High voltage operation
- Super capacitor for a last gasp power source
- Remote data acquisition and transfer
- 1200V inbuilt switch provides flexibility to make a robust and low-cost system
Applications
- 3-phase energy meters
