Optimising efficiency in transformer performance calls for low loss, low reluctance magnetic design, a feature which normally goes hand in hand with high inrush currents and switch-on surges, making such a transformer difficult to switch on and control.

Traditional solutions to this problem rely on current inrush suppression components or circuits in series with the primary winding of the transformer, such components and circuits can become a weak point in systems where reliability is paramount.

The Noratel 3RT-LI range of transformers do not rely on such protective components but instead have very low inrush current capability “built-in” to the design. This results in a transformer that offers outstanding efficiency combined with ease of switch-on and control which maximises reliability and minimises the transformer’s impact on sensitive power systems and protective circuitry.

The 3RT-LI range of transformers can start up without issues on standard Type C characteristic MCBs which makes the 3RT-LI range not only cheap to install, but such low inrush makes it the first choice in UPS and semiconductor driven power systems also.
