Conzerv EM6434 DigitAN Panel Meter - power, energy

The EM6000 DigitAN panel meters are TRMS three phase multi-function panel meters for use in control panels, motor control centers (MCCs) and genset panels. As such EM6000 meters are compact, rugged, durable and are easily installed.

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.  Displays all power and energy parameters, Run hours, ON hours & number of power interruptions and monitors loading characteristics of motors

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 auxiliary power supply that can run on AC or DC power from 44 - 300V.

The EM6434 includes an RS485 communications port to communicate with PCs, PLCs and DCS.

Capabilities specific to this product, the EM6434, are :

• Power: Total and phase-wise (kVA, kW, kVAR)
• PF: Average and phase-wise
• Energy Parameters (kVAh, kWh, kVARh inductive and kVARh capacitive)
• Accuracy Class 1.0 or Class 0.5
  
• Built-in RS485 port

Note : This product is purely an energy and power meter and does not display voltage, current or frequency.
