Voltage Sensor Transformer Single Phase to 3 Phase High Voltage Sensor to 4 20mA Converter AC Voltage Transducer 4 20mA Output. Ultra-High Voltage Capability: Reliably measures and isolates extreme electrical potentials up to 2000V (AC or DC), making it ideal for renewable energy and heavy power grids. True RMS & DC Universal Sensing: Capable of measuring complex AC waveforms (True RMS) and pure DC signals with high linearity and zero calibration drift. Excellent Galvanic Isolation: Features strong input-to-output-to-power isolation (up to 3.5kV), completely eliminating ground loops and preventing catastrophic voltage spikes from damaging control roo. Flexible Signal Connectivity: Seamlessly interfaces with modern automation and IoT systems, offering standard 4-20mA, 0-10V, and digital RS485 (Modbus RTU) outputs.
