Measuring transducers for direct current and direct voltage for installations up to 1000 V (CAT III) with standard signal
Measuring transducers for direct current and direct voltage
for installations up to 1000 V (CAT III) with standard signal outputs
Typen IgTT-MU | UgTT-MU
Areas of application: Photovoltaic systems, wind power and other installations up to a voltage of 1000 VDC.
The lgTT-MU and UgTT-MU measuring transducers serve to convert and isolate a direct current or direct voltage into an impressed direct current and direct voltage signal. An integrated limit monitoring is used to monitor the input signal.
The measurable variable reaches the amplifier or impedance transformer via an input protective circuit. The direct voltage obtained here is transformed into an impressed direct current and impressed direct voltage. The galvanic isolation is by means of an optocoupler. Both outputs are protected against no-load and short-circuit. Connecting the two outputs is not permissible. The limit can be set in the range 0 – 120% of the input signal. If the limit is exceeded, a LED indication is given. An auxiliary voltage is required.
