ITL-300 Power Transmitter





ITL-300 Models Specifications Datasheet

Introduction

The 3-phase Power Transmitter ITL-300 measures power in 3-phase systems. Due to its wide frequency range DC-10kHz, it can also be used to measure power in thyristor controlled circuits and frequency inverter systems.
The 0-20mA output signal is galvanically isolated from the transmitter input circuitry. In the 50/60Hz three phase system current is measured via current transformers. In thyristor controlled circuits with high current harmonics and in variable frequency inverter systems current must be measured via Hall sensors.

ITL-300 current ranges 50mA / 100mA / 200mA are provided for current outputs from Hall sensor modules. A 3-phase current sensor module for current ranges 25A / 50A / 100A is available.
