Description

Faced with limited resources and booming demand, the energy industry seeks greater efficiencies within complex energy management and distribution processes, all while providing the best consumer experience. To achieve better service and smarter, streamlined processes, energy providers require reliable, real-time access to data.

A smart plug controls the energy supply of devices connected to it. Using a ZigBee® interface this device connects to a gateway where you can send commands to turn on/off or see the power consumption of the device connected to it.

Features

• Tamper detection with time stamping
• USB battery charging (CC/CV) and Energy Star 2.0 compliant
• Very low current solution for long battery life
• System BOM is low in component count and cost
• 6 LED drivers
• Integrated power amplifier for long range and robust communication
