Application

In production lines with electric overhead conveyors (EOC), the safe phase monitor specifically monitors conductor rails. If a rail is switched off, the device detects this and thus enables the controlled shutdown of a system. 

For drives that can feed energy back into the grid (e.g., during braking), the phase monitor ensures that energy is only fed in when the supply voltage is correct, complete, and stable.

 

Phase Monitor SAFEONE DN3PW1

 

The SAFEONE DN3PW1 monitors the three phases of the supply voltage of electrical systems or system components for phase relationship and voltage values. In the event of a fault, it reacts within at least ten milliseconds. The switching device is not intended for safety-related applications.

Application

The phase monitor is used to monitor the supply voltage of machines operated under unstable grid conditions. If a grid failure is imminent, the device detects it immediately and enables movements to stop or reverse in time to prevent damage to workpieces, tools, or system components.

For drives that can feed energy back into the grid (e.g., during braking), the phase monitor ensures that energy is only fed in when the supply voltage is correct, complete, and stable.
