Bticino m7000cbndps - modulo alimentazione duale

The module for double auxiliary power supply allows you to automatically select the most suitable between two single-phase AC power supply lines. The selection criterion is based on the presence of voltage within the minimum and maximum pre-established limits. Its typical application is to supply auxiliary power to switches and control devices inside an emergency switching panel. It can therefore be used in conjunction with automatic network switches. Switching between the two lines is carried out with defined and repeatable thresholds and times, guaranteeing system safety. The two lines are separated with electrical safety interlocks. A self-diagnosis is also performed under the supervision of a microcontroller. In case of lack of both power supply lines and \/ or self-diagnosis of operating anomalies, an additional alarm relay signals the alarm status to external devices.
