It supports auto and manual operation with mechanical & electrical interlock, widely applied for fire control, commercial and industrial uninterruptible power supply.
MLQ5 series 4P PC-class Automatic Transfer Switch (ATS) is a key lock type dual power changeover switch equipped with control terminal blocks. It is used to automatically switch between two independent AC power sources. When the main power supply fails, the ATS transfers the load to standby power to ensure uninterrupted power supply for important electrical equipment. This series has four current specifications: 160A, 250A, 400A and 630A to meet different load requirements.
This ATS adopts integrated PC-level structure, built-in mechanical interlock plus electrical interlock protection, which can effectively prevent the two power sources from being connected at the same time and avoid dangerous short-circuit accidents. It supports automatic and manual dual operation modes. The external terminal blocks make wiring of control signals simpler.
