Installation and Operation CT-100/CT-150 Series User’s Manual
transducer is correctly working while it is at high level (>14.5V) when the transducer
is not.
In the configuration presented in
Figure 11
, the current transducer can be easily
interfaced to a digital microcontroller, a Digital Signal Processor or an FPGA, supplied
by a +3.3V voltage source.
Please note that the +3.3V supply and the OK_SIGNAL is referred to DGND
potential, which can be the same or different from the GND potential on which the CT
device is supplied from. The OK_SIGNAL is found to be at low level (<0.4V) when
the transducer is correctly working and at high-level (>3V) when not.
Figure 12: STATUS – OUT OK indications
The OUT OK green light is on, as shown in
Figure 12
, whenever the device is
correctly working and regulating secondary output current – i.e. zero flux is established
and secondary circuit is closed on the shunt resistor (external or internal in the “V”
versions).
