Universal high voltage transducers. Input currents up to Iin = 5 A.
The VariTrans P 43000 isolation amplifiers have been conceived for direct measurement of currents up to 5 A (DC). They reliably isolate high potentials at the input circuit.
The isolating distances are designed to withstand permanent voltages up to 3600 V AC/DC and fast transients up to 20 kV. Protection against electric shock is achieved through protective separation according to EN 61140 between input and output and power supply.

The Task
In high-voltage systems, unipolar or bipolar currents ranging from 100 mA to 5 A must be galvanically isolated and converted to standard ±20 mA, ±10 V or 4 … 20 mA output signals.
The Problems
In the case of insufficient insulation, high voltages and harsh ambient conditions may overload the galvanic isolation. This can result in false measurement values or even personal injury or damage to the equipment. These risks have to be eliminated safely and over the long term by suitably designed high-voltage transducers.
The Solution
The VariTrans P 43000 high-voltage transducers have been specially conceived for direct measurement of currents up to 5 A AC/DC. They reliably isolate high potentials at the input circuit.
The isolating distances are designed to withstand permanent voltages up to 3600 V AC/DC and fast transients up to 20 kV. Protection against electric shock is achieved through protective separation according to EN 61140 between input and output and power supply.
