DESCRIPTION
:
The NT511 is a comby unit to control the temperature of MV dry type and cast resin  transformers and the power of the fan cooling system. It is recommended with the use  of tangential fans, thanks to the presence of 6 outputs 230 Vac 1.5 A max. (each).

Every single fan is protected by a fuse and in case of failure the unit provides a FAULT  signal. The metal structure is designed for installation on the box of the transformers.  4 Pt100 inputs allow the reading of the temperature of the 3 windings and possibly of the  core or the ambient. The unit is equipped with dry contacts to signal FAULT, ALARM and  TRIP. For the control of the fans there are 6 active outputs that provide power directly to  the fans.
