Introduction
 PA310-400 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 400A). PA310-400
can also maintain better than 1% (IEC-62053-21) accuracy even under low current condition (< 5A), thus
it still can be used in middle to high voltage system. The unique features of PA310-400 including: Clip-on type
CT, bi-directional measurement, long time load recording, and standard communication. Its compact size,
easy installation, and low cost make PA310-400 suitable for modern electricity monitoring and load investigation.
Features
Clip-on type CT, Easy wiring for on-line installation
- With wired clip-on CT (various types support input current up to 400A)
- Wh accuracy better than 0.5% (PF=1)
- Up to 10000 load profile records with configurable recording period
- RS-485 communication supported Modbus protocol
