PROTECT THE TEMPERATURE OF YOUR TRANSFORMER WITH THE NEW SERIES T1048! INTELLIFAN The Intellifan function allows you to reduce the thermal shock on the transformer anticipating partially (one bar at a time) the activation of the ventilation system. Enabling FAN INT. “YES” the unit will alternate, each 30 minutes, the activation of contacts FAN1 and FAN2, anticipating the activation of the ventilation system to the intermediate value between FAN1 ON AND FAN1 OFF. VOTING Taking advantage of the principle of redundancy, we use the probes installed on the three phases U‐V‐W to monitor the operation...
