Alvi Technologies introduces a new range of compact high voltage transducers from Knick featuring safe galvanic isolation.
Transmission of measuring and control signals at major industrial plants and sites almost always requires electrical isolation of the signals being processed, for safety as well as optimum signal quality. Knick offers reliable components for electrical isolation in various designs to meet these requirements.
Knick’s Proline series isolation amplifiers are designed to deliver high accuracy in critical applications. The Proline series has proven itself in all technical parameters including insulation level, transmission properties, flexibility, compact design, ease of use and energy efficiency.
The VariTrans P42000 from the Proline series is a range of isolation amplifiers specially designed for measuring high voltages up to 3600 V (DC) and reliably isolating high potentials at the input circuit. The VariTrans P42000 is widely used in the rail industry.
Key features of VariTrans P42000 isolation amplifiers include conversion of input voltages up to 3600 V AC/DC into impressed output signals ±20 mA, ±10 V or 4 ... 20 mA; extremely compact modular housing; protection against electric shock through protective separation up to 1800 V AC/DC according to EN 61140; and excellent transmission properties: gain error <0.3%, cut-off frequency>5 kHz, and rise time T90 <0.1 ms.
The VariTrans P42000 also offers tremendous flexibility thanks to calibrated switching of up to 16 input/output ranges, up to 16 customer-specific measuring ranges, and broad-range power supply 20 V to 253 V AC/DC. Functioning reliably even with unstable supply, the isolation amplifiers are suitable for direct current rail systems up to 3000 V DC; and are mechanically stable when used on ships, trains and vehicles.
