PEM
Overview
RCTi-3ph is a fixed AC current sensor. It is equipped with a slim, lightweight, and flexible Rochi induction coil that can be bent, featuring a snap-open closure structure.Easy to install, also suitable for retrofitting older devices。
The instantaneous voltage of the secondary output of the sensor is proportional to the primary current being measured, which can achieve measurement of the primary current.High accuracy, low cost, wide frequency rangeTesting.
This product is often used with power meters, harmonic testers, ammeters, oscilloscope, data loggers, and data acquisition cards, and is widely used in various power quality monitoring scenarios.
Product Features:
-
Easy to modify, easy to install in space-limited applications, non-intrusive—no need to draw power from the main circuit, wide bandwidth up to 1MHz,
Used to measure harmonic components or complex waveforms (such as induction heating, VF drive, power measurement)
The size of the Rogowski coil can be specified independently of the primary current.
Will not happenmagnetic saturation
Intrinsic Safety
Equivalent to Class 1 current transformer or better, suitable for low-cost monitoring of medium/high currents.
