POWER MEASUREMENT INSTRUMENT

PA3 is a high-accuracy multi-function meter that provides wide range of power parameter measurements and can be applied to the power monitoring of general single-phase and three-phase systems. With Its compact size, easy installation, and low cost make PA3 suitable for modern electricity monitoring and load investigation.

- Power Controller is widely used for power monitoring and control in factory and building. - Manage up to 16 units of power meter - Rich electricity parameters and power quality display for main and sub-feeder meter - Power Controller is easy integrated with 3rd party supervisory control systems - Remote power monitoring and control via intranet/internet - Electricity demand control with 16 channel load shedding - Multi-tariff management with TOU (Time-of-Use rate) - Built in web server remote monitoring and control & data download - Automatic report and alarm status sending by E-mail - Front USB host port for data backup and program download

A33/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 (

Clip-on CT Power Meter is designed for electric power monitoring and load recording for single or three phase systems. It can be directly used in low voltage systems due to its wide range measurement (up to 60A). PA310 can also maintain better than 1% accuracy even under low current condition (< 5A), thus it still can be used in middle to high voltage system. The unique features of PA310 including：clip-on CT, bi-directional measurement, long time load recording, and standard communication.

Multi-Function Power Meter is designer for single and three phase power monitoring and measurement. Multi-Function Power Meter provides wide rang of measurements including current, voltage, energy, watt, power factor, watt-hour and frequency, etc. Multi-Function Power Meter also build-in RS485 can easily integrated with most third SCADA system. DIN 96*96 standard compact size enable PA330 to be easily installed and its low cost and wide flexibility application also made PA330 a good choice for modern power monitoring.

Ethernet-enabled revenue class multifunction meter for power measurement, power quality analysis, and power usage reporting PA3000 series Smart Power Meter is designed for continuous monitoring of 3 phase system. All essential power parameters including current, voltage, power, active and reactive energy are integrated in a single meter. Its bi-directional energy measurement and harmonic analysis function makes PA3000 suitable for modern industrial power management. The built-in Ethernet and rich communication abilities enable Smart Power Meter to be easily connected with most modern third-party SCADA systems.
