High Voltage Isolator with True RMS Measurement

Precise measurements at high working voltages up to 3600V and a true rms measurement are the domain of the ProLine 42000 high voltage signal isolator.

 

The ProLine name symbolizes our range of unparalleled signal isolators and conditioners. Due to its recognized reliability ProLine is widely used in industrial instrumentation and control around the world.

 

ProLine 42000 offers input voltages ranging from 10 to 3600 V AC that can be safely measured and converted to standard DC analog signals (0…20 mA, 4…20 mA, 0…10 V). These transducers are available with up to 16 different I/O settings as well as the capability to be customized with fixed input and outputs for voltages anywhere between 10 and 3.6 kV AC.

 

Thanks to internal true RMS measurement and conversion – distorted and non-sinusoidal input signals, that cause serious measurement errors, are correctly identified and transmitted. The true RMS measurement circuit converts signals with a crest factor of up to 5. With the high insulation properties required for working voltages of up to 3600 V AC and following the safety requirements of EN 61010-1 and EN 50124-1, the design is well suited for harsh conditions, such as the electrical systems on ships, rail, land and military vessels. Internal components are vacuum encapsulated to ensure protection from aggressive environmental influences such as particle ingress and also create mechanical stability for high shock and vibration specifications. Additionally, protective separation of the input, output and power supply provide protection from electric shock up to 1800 V AC/DC according to EN 61140.
