IU-UU Measuring Transducer
Measuring transducer for converting a voltage (±30V / ±100V / ±270V) and a current (±7.5A / ±15A / ±30A / ±60A) into a ±10V standard signal up to 1 MHz.
Intended purpose:
The signal converter is intended for voltage and current measurement on electrical components from the automotive sector (e.g. motors, injectors, pump valves, etc.).
Highlights
- The measuring range of the current ±7.5A / ±15A / ±30A / ±60A to ±10V is switchable internally.
There are no switched contacts in the current path. - Measurement of the current is isolated for the measurement output and isolated for the supply voltage.
- If required, the measuring voltage can be supplied directly from outside to the selected measuring range ±30V / ±100V / ±270V to ±10V. This makes it possible to set up correct voltage measurement.
- The voltage measurement is differential to the measurement output and isolated for the supply voltage.
- Potential separation between measurement ground (AGND) and supply ground (GND).
- The smaller measuring ranges are overload-proof up to the regular maximum measuring range 60A / 270V without damage.
- Reverse polarity protection for operating voltage.
