The T119 is a unit developed to control the temperature of MV cast resin and dry type transformers. The use of Ptc temperature sensors according to DIN 44081 and 44082 makes it particularly simple and economical. Entrusted the management unit to a microcontroller allows to maintain a high level of reliability. The 3 Ptc sensor inputs refer to the alarm thresholds (ALL1), trip (ALL2) and ventilation (FAN). Each input can be connected by 1 up to 9 Ptc’s in series. Any sensor or unit anomalies reported as FAULT alarm. 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
