The ATS cabinets are designed for installation at facilities of a special group of electric consumers of I category, uninterrupted operation of which is necessary for accident-free power supply of industrial, municipal, banking and other power consumption facilities.
Power supply of ATS consumers is carried out in the normal mode from the main input. Constant control of voltage availability is carried out in the circuit of the main (input No.1) ATS power supply source. In case of voltage loss at the main input ATS makes automatic switching to the reserve input. Reversible mechanical blocking of ATS does not allow simultaneous switching on of different inputs that allows to avoid short-circuiting of phases with different potentials.
Light indication of the operation mode of each ATS input is provided. When voltage is restored at the main input, automatic return is performed. The nominal operation mode of ATS of both main and reserve inputs is continuous.
