Overview
The Voltage Sensor Amplifier is designed to allow a single voltage sensor (per phase) to interface with multiple IOMOD Meter and IOMOD FPI devices, eliminating the need for amplitude and phase correction.
Enhance your engineering applications with our advanced three-channel Voltage Sensor Amplifier. Engineered for high precision, it provides a stable impedance load to maintain the accuracy of voltage sensors. With a gain factor of 1, it ensures signal fidelity without distortion. Facilitate the simultaneous connection of multiple metering devices to a single voltage sensor, eliminating the need for complex amplitude factor calculations and tuning. Optimize your measurements with this robust and technically sophisticated solution.
This device is engineered for applications such as sub-metering, machine monitoring, calibration checks at consumer locations, power measurement, data logging, and power quality analysis. It’s compatible with FTU, DTU, Bay Controllers, Multifunction Protection Relays, Merging Units, and RTU applications.
Features
- Very simple installation
- Not affect amplitude and phase correction
