iMeter 6 Advanced Power Quality Monitor
Device Introduction
- The iMeter 6 is CET’s latest offer for the advanced Power Quality Monitoring of Incomers and Critical Feeders for Utilities, Data Centers, High-Tech Manufacturing Facilities and Heavy Industries. Housed in an industry-standard DIN form factor measuring 96x96x119.5mm, the iMeter 6’s compact size is perfectly suited for today’s space restricting environment.
- iMeter 6 features quality construction with metal enclosure, advanced Power Quality and Revenue-Accurate measurements, High-resolution Waveform Recording Capabilities, comprehensive Data Logging with 2GB memory, extensive I/O and a user friendly, IPS Color Dot-Matrix Display @ 320x240. It also provides either an I4 Input for Neutral Current Measurement or a 0/4-20mA Analog Input for measuring external transducer signal such as Residual or Leakage Current. With a standard 10/100BaseT Ethernet Port and an RS-485 port supporting multiple protocols, the iMeter 6 becomes a vital component of an intelligent Power Quality Monitoring System.
