WRCS III – Wide range current sensor
Sensor for current measurement from 1 μA to 200 A
Today’s automotive ECUs switch to an energy-saving mode with very low standby current while the car is powered down. The high-precision current transformer WRCS III measures highly dynamic currents of very few microamperes up to 200 ampere with a fast, automatic change of measuring ranges (auto-range).
Available as a single unit as well as a 19” rack with up to 13 channels, 6 physical measuring ranges provide excellent accuracy from typically 0.1% (at the end of the measuring range) at any current.
Apart from four freely configurable analog outputs for connecting devices such as data loggers (permanent operation, test facility) or oscilloscopes, an OLED display shows the active current with the measuring range used and a simple progress overview.
A multiplexed analog output allows the recording of each measuring range with a single data logger only.
During the use of low sampling rates for the data logger, configurable filters with time constants up to 10 s prevent aliasing.
The measuring channels are galvanically isolated from the analog outputs (100 V).
An adjustable electronic circuit breaker with configurable tripping time constant completes the features of the WRCS III.
