Conzerv EM6459 Panel Meter - volts, amps, frequency, power factor (only)
This product is designed to measure three-phase three wire or four wire systems to 480V. It can also measure three single phase two wire systems. It is accurate on distorted waveforms and allows the user to set transformation ratios for both potential transformers and primary and secondary current transformers and has a built-in phase analyzer.
The Conzerv EM6459 Panel Meter displays Volts, Amps, Frequency/PF simultaneously and monitors generator speed (RPM); generator loading efficiency also, ON hours & number of power interruptions
The display features five buttons for configuring and reviewing data, a large illuminated LED display with an analog 'load bar' for easily viewing system load.
The unit receives power through an auxilliary power supply that can run on AC or DC power from 44 - 300V.
There is an optional RS485 communications port to communicate with PCs, PLCs and DCS.
Capabilities specific to this product, the EM6459, are :
- Voltage: Phase to Phase and Phase to Neutral - Average & Individual
- Amp: Average, phase wise, phase degrees
- Line Frequency
