PA310
PA310 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 current measurement (up to 1000A). PA310 can also maintain better than 1% (IEC62053 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 including : internal 5A CT or Clip on CT, bi directional measurement, long time load recording, and standard communication. Its compact size, easy installation, and low cost make PA310 suitable for modern electricity monitoring and load investigation.
Features
- Clip on CT, easily wiring especially for on line installation
- Optional in 5A CT(internal), without Clip on CT
- Wide measurement range10(60)A, max to 1000A suitable for low voltage system
- Meter ID can be set up through the panel buttons
- Wide measurement range, suitable for low voltage system
- Wh accuracy is better than 0.5%(pf=1)
- Up to 10000 load profile records with configurable recording interval
- RS485 communication support Modbus protocol
