Product Overview
1856B05 uses the electromagnetic isolation principle with a high speed DSP and a professional MCU controller to isolate and measure the full electrical quantities of a three phase system. Measured parameters are three phase voltage (RMS), three phase current (RMS), active energy (signed), active and reactive power (signed), apparent power, power factor (signed), frequency, 1st to 19th harmonic voltage and current components, and positive, negative and zero sequence voltage and current. The output is an RS485 communication port.
The product has total galvanic isolation between input, output and auxiliary power, high accuracy, compact size, low temperature drift and a wide temperature range, and is cost effective. It is used in the protection systems of electric motors and in power supply and distribution systems.
1876B05 uses the electromagnetic isolation principle with a professional MCU controller to isolate and measure the full electrical quantities of a three phase four wire system.

Questions Buyers Ask
What is the difference between 1856B05 and 1876B05?
1856B05 adds harmonic analysis to the 19th order and the sequence components, using a high speed DSP. 1876B05 covers the standard three phase four wire quantities with an MCU controller.
Does it replace a meter?
It replaces the analogue transducers and gives a digital feed. Where a local display is needed, pair it with a panel meter from the same range.
What isolation does it provide?
Total galvanic isolation between input, output and auxiliary power.
