DatasheetThe unit avoids interference voltage carry-over and effectively suppressing parasitic noise. The very low drop voltage of 2.3 V and the high level of accuracy work together to make the DH 11000 the first choice in system design.
Intelligent design and their consequential avoidance of highly integrated components result in extremely long service lives and reliability – without any falsification of the measurement signal.
The DH 11000 requires no additional power supply since the auxiliary power is obtained from the input signal without distorting it. This not only saves costs during installation, but also increases reliability.
