Working voltages up to 1000 V AC/DC and test voltages up to 5.4 kV AC, maximum performance in a compact modular housing.
High-voltage VariTrans P 29000 series isolation amplifiers are available in two input versions for a variety of requirements: high voltage, mV. The devices are ideal for monitoring and controlling electrical drive systems operated with DC voltages and feature a passive output for direct connection to a supplying PLC. Input voltages from ±100 V to ±1000 V DC are galvanically isolated and provided at the output as standard 0/4 … 20 mA or 0 …. 10 V signals or as a bipolar signal in the range of -20 … 20 mA or -10 … 10 V.
Typical applications are DC current and servo drives, generators etc, as well as power supplies for welding units and inverters for solar or wind power systems. The extraordinary performance and flexibility of the isolation amplifiers supports the user in the development of the most diverse products or system solutions.
When it comes to taking measurements on power electronics, unipolar or bipolar voltage signals ranging from 20 mV to 1000 V must be galvanically isolated and converted to standard ±20 mA, ±10 V, or 4 … 20 mA output signals.
Room in the enclosure is limited and expensive. Therefore great value is placed on the miniaturization of automation components. And high safety requirements with regard to the protection of persons and systems must also be met.
The VariTrans P 29000 isolator series is designed specifically to measure voltages up to 1000 V AC/DC. The test voltage is 5.4 kV AC. Protection against electric shock is achieved through protective separation according to EN 61140 between input and output and power supply up to 600 V AC/DC.
Compact automation solutions can be implemented thanks to the 17.5 mm modular housing and operation at temperatures up to 70 °C.
