APM530 Power Meter

APM530 multifunction power meter is a robust and cost-effective electricity meter which adopts micro-electronic technology with a special integrated circuit. It has anti-EMI and low-power features and is widely used in office buildings, shopping malls, residences, airports, metro stations, and more.

•    Easy to install and operate

•    Easy circuit breaker monitoring and control

•    Direct metering of neutral circuits and calculated ground current values to avoid overload and resulting outages (PM556x)

•    Power quality analysis

•    Load management combined with alarm and timestamping

•    High performance and accuracy

•    BACnet/IP protocol support
