MOBILE APPLICATION

The NT511 is a combined unit to control the temperature of dry transformers and the power of the fan cooling system.

In AD version, it is simultaneously equipped with Analog 4-20mA and Digital RS485 Modbus RTU outputs.

It is recommended with the use of tangential fans, thanks to the presence of 6 outputs 230 Vac 1.5 A max. (each).

Each fan is protected by a fuse and in the event of failure, the unit provides a FAULT signal.

The metal structure is designed to be installed on the transformer box.

4 Pt100 inputs allow the reading of the temperature of the 3 windings and in the case of the heart or the atmosphere.

The unit is fitted with dry contacts to signal FAULT, ALARM and TRIP.

For fan control, there are 6 active outputs that supply power directly to the fans.

All our units can also be supplied with a special coating on electronic cards, resistant to harsh weather conditions, particularly characterized by high temperature and humidity (which are in tropical climates).
