The Master Switch Single-Phase (MMS) is a transfer switch designed to safeguard loads with varying power ratings. With a manual bypass, switching power sources in the case of a problem is simple.
The MMS is outfitted with an LCD control screen and a multi-functional keyboard. This allows you to rapidly and intuitively check measurements and alter operational states. It includes three dry contacts, an RS232 port, and a communications slot for future LAN connections.
To safeguard the load, the changeover time is assured to be shorter than a quarter of a cycle (4 msec for synchronised inputs; 10 msec for non-synchronised). This is true for both automatic and manually operated switches.
