Remarks:
Available with primary inserted conductor (CTSR xxx-TP model)
Designed for single or three phases residual current measurement (up to +/- 30A per wire, DC or AC)
Easy insertion of earth leakage wires thanks to the aperture (? 20.1 mm)
Bipolar currents measurements when single supplied 0/+5V
Self test function
Demagnetization function
These transducers can directly be connected to the 5V input of μ-controllers and instrumentation cards
CTSR models have an additional pin at the output for more flexibility in applications. This pin provides access to the internal voltage reference which can then be fed to the reference of an A/D converter (Analog Digital) This extra pin can also receive the internal reference (from 2.3 to 4 V) of the DSP (Digital Signal Processor) or A/D converters commonly used in Power Electronics, allowing cancellation of the reference temperature drift
Low current consumption
High overload capability
Possibilty to easily design up to 3 ARMS nominal version under request
