The Relink-2s enables the drive of a step transformer through a 0-10V signal. It is especially designed to control Mf-Net transformers (such as the STW-A, the STD-A and the SEA). The Relink-2s can also control non Mf-Net single phase transformers up to 10 Amps. To deal with currents higher than 10 Amps or with three-phase transformers, additional contactors could be necessary.
