PA33/PA34 are designed for general single phase or poly phase power measurement.
With wide range, Compact Smart Power Meter can be applied either on low voltage primary side or medium/high voltage secondary side for its high accuracy (<1%, IEC62053-21) under 5A current. Its compact size, easy installation, and low cost make PA33 suitable for modern electricity monitoring and load investigation.
