STM Inverter System

The STM series comprises of an integrated power system with inverter, monitor and static transfer switch functionality. This modular inverter is a redundant inverter which can be composed into an N+1 redundancy system. In the case of a master fault, the digital control rapidly and automatically switches to a new master, leaving the load uninterrupted.
The hot swappable design makes maintenance and expansion of the system simple. The inverter has sinusoidal output as well as stable output voltage in static and dynamic conditions.
