Product details about "NT539 Controller"


Electronic microcontroller unit, specially designed to control transformers with more than three windings, such as those used in DC / AC conversion systems / systems; the NT539 can also be used to control the temperature of MV / LV distribution systems with three-phase transformers.

It is equipped with 9 Pt100 inputs and the following relays: 3 for the ALARM, 3 for the TRIP and 3 for the FAN cooling system.

In addition, there is another FAULT relay in common with the whole system to signal a sensor fault or any other problem inside the device.
