THYRO-A® H3 / H RL3 / H RLP3

Thyro-A Digital SCR Power Controller With Enhanced Features

With highly flexible interfacing for the load and power supply side, Thyro-A® modules precisely and reliably control power in an expanded range of applications. For standard processes, adjustments can be made on the unit itself, which eases handling and speeds commissioning. Interfacing at the automation level enables expanded functionality.
