Low power transformer TUP80RV

Low power current transformer with millivolt (225mV) output designed for Smart Grid monitoring. This product is designed to be installed directly on insulated medium voltage cables. The resin encapsulation and plastic casing allows the current transformer to be installed directly outdoors. All this makes it possible for the transformer to function optimally without its characteristics being affected or suffering any degradation over time.



  • This transformer can have the P1 side in a different color to make it easy to distinguish the polarity.
  • The secondary connection is made with a cable terminated in a RJ45 connector, with pins 1 (S1) and 2 (S2).
  • Mounting on isolation panels on distribution cabinets in medium voltage substations.
