PRODUCT DESCRIPTION
The RTVS1 series of transformer fan speed controllers regulate the rotational speed
of single-phase voltage controllable motors in five steps by varying the output
voltage. They are equipped with auto-transformer(s) and feature Modbus RTU
communication, TK monitoring for thermal motor protection.
