The Raptor SL features toroidal windings that are activated individually by the master unit as the power demand grows, through a sophisticated injection control that ensures seamless current flow and optimal workload distribution.

The slave Raptor is visually identical to the master unit but lacks the measurement section, the handheld controller and the auxiliary input/output panels. Its mission is to push an additional 5 kVA power to the high current pass-through secondary. Up to three slaves can be added for up to 15,000 A with a 18-kVA total injection power. The master unit detects the presence of slaves using infrared communications, so no additional control or power interconnections are required. The user only needs to pass the current cables across the entire assembly and use it as if it was a single device, in a fully transparent way to the user. As an added benefit of the pass-through secondary technique, the user can easily multiply the compliance voltage by making more than one turn with the current conductor around the entire system.
