Product features NT133-3 controller

The NT133-3 is a complete and simple unit, for sophisticated temperature control of HV and MV power transformers.

With just one device, you can control the temperature of the oil, control the cooling system and calculate the thermal image of the 3 windings with an exclusive algorithm.

The unit is equipped with a double Pt100 input for redundant control and 3 universal inputs for current transformers (CT). 
The output relays are available for: ALARM, TRIP, VENTILATION of the cooling system, control of the oil circulation PUMP and indication of FAULT.

The unit is also equipped with a Modbus RS485 output for remote control functions.

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.
