P43000 TRMS AC/DC High Voltage Transducer / Transmitter
Product number:
P43000TRMS
Description
P43000 TRMS AC/DC High Voltage Transducer / Transmitter
- Universal usability:
- AC input 100 mA~ to 5 A~
- DC output 0 (4) … 20 mA, 0 … 10 V
- Working voltages up to 3600 V AC/DC
- TransShield technology
allows for extremely compact modular housing - Protection against electric shock
through protective separation up to 1800 V AC /DC according to EN 61140 - Test voltages up to 15 kV AC
- Outstanding transmission properties:
- Gain error < 0.5 % with crest factor < 3
- Gain error < 1 % with crest factor 3 … 5
- Response time T90
- Virtually no influence from common-mode voltages:
CMRR approx. 150 dB - Tremendous flexibility thanks to:
- calibrated switching of up to 16 input/output ranges
- up to 16 customer-specific ranges
- VariPower broad-range power supply 20 V to 253 V AC/DC
- Reliable function even with unstable supply
- No damage
in the case of erroneous power connection - Switchable models
reduce variety of versions, thus saving storage costs - Robust
thanks to vacuum encapsulation - Mechanically stable
for operation on ships, trains and vehicles - 5-year warranty
The P43000 TRMS isolation amplifiers have been specially conceived for measurements of bipolar currents ranging from milliamps up to 5 amps. They reliably isolate high potentials at the input circuit. Thanks to the true rms conversion in the transducer, even distorted input signals are captured correctly and output as so-called true rms values.
The isolating distances are designed to withstand permanent voltages up to 3600 V AC/DC and fast transients up to 20 kV.
We look forward to hearing from you!
