The VSM10 Voltage Sensing Module can detect the exact line voltage characteristic and supports fault-free operation of Line Modules when power supply conditions are unfavorable, e.g. with severe voltage fluctuations or short-time interruptions.

The VSM10 Voltage Sensing Module is integrated in chassis format Active Interface Modules and in the chassis format Smart Line Modules. It can be used optionally with all booksize format Active Line Modules and 16 kW, 36 kW or 55 kW Smart Line Modules.
