The EVS30 DC or AC Voltage Transducer uses special Isolation Barrier technology to measure AC and DC or Pulsed voltages. The primary input voltage and the output signal is highly electric isolated. It can be used in Power Utility, Converters, Traction, Telecom, Oil & Gas, and New energy fields.
Features
• AC, DC, Pulsed voltage measurement
• Included primary resistor
• Good linearity
• Galvanic isolation between primary and secondary circuit
• Low power consumption
• High immunity to external interference
• Low thermal drift
• Higher voltage can measure than EVS30
