The LQI5 is a precision direct current measurement card. It features 6 measurement ranges for unipolar current measurements of up to 32 A. Current pulses shorter than 5 seconds can be measured up to 65 A.
As a special feature an auto range function is included. If the measurement falls below the current measurement range or exceeds it, the LQI5 switches within 5 µs into the next higher or lower range. This ensures that the module always measures in the optimal measurement range and possible damages are avoided. The changing in a lower measurement range can be deactivated via software when measuring pulsating signals.
A measurement is done every 1ms and the result can be read via software or the card sends in 1ms time frames the measurement values automatically.
The LQI5 was designed as a slot card for the MFTS100 system and can also be used in different qualification testers.
