MOBILE APPLICATION

NT935 is a unit based on electronic microcontroller specially designed for dry transformers.

Developed with the layout and advantages of the new technological platform (dual display, VOTING function, new microcontroller with operational capacity and increased data management), the NT935AD provides the user, in a single product, with the outputs :

• 4-20 mA analog

• Modbus RTU digital RS485.

Capable of monitoring the temperature of the transformer like T154 standards, thanks to the remote communication system, in addition to transmitting temperatures in real time, offers the possibility of varying all parameters, including the relay intervention thresholds.

It is equipped with 4 Pt100 inputs to monitor the winding temperature and / or the ambient temperature (4 ° channel) and thanks to the versatility of the new 2016 edition, other sensor inputs are available. The protection relays are 5: ALARM relay to signal high temperatures, the TRIP relay disconnects the transformer if it reaches the maximum threshold, the FAN1 and FAN2 relays to start the ventilation system, the FAULT relay to signal any faults.

On request, the unit is available with certification for the Canadian and American market UL, as well as for marine applications.

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).

UNIVERSAL SUPPLY: with input from 24 to 240 Vac-dc.
