NT539
Temperature Control of Cast Resin & Dry MV Transformers
NT539
Code: 1CN0023
N. & type inputs: 3-6-9
Outputs: 10 relays (3 alarm, 3 trip, 3 fan, 1 fault
Plus: for trafo with more then 3 windings
Electronic microcontroller based unit, specifically designed to control transformers with more than three windings, such as those used in the conversion DC/AC plants/systems; the NT539 can also be used to control the temperature of distribution MV/LV systems with three phases 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.
Furthermore, there’s another FAULT relay in common with the whole system, to signal a sensor fault or any other problem inside of the unit.
All our units can also be supplied with a special coating on the electronic cards, resistant to difficult weather conditions, particularly characterized by high temperature and humidity (which are in tropical climates).
UNIVERSAL POWER SUPPLY: with input from 24 to 240 Vac-dc
