signal isolator / galvanic / high-voltage / bipolar

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.
