STM250-24 Modular Inverter System


STM250-24 Modular Inverter System


STM250 series is a rack mount inverter system housing up to four inverter modules and a monitor module with built-in ATS (Automatic Transfer Switch). The versatile modular design with hot swappable modules and no single point of failure is increasing system reliability. Real time system parameters and alarms are displayed on the monitor LCD screen.

The system supports up to 4 x 1kVA inverter modules, type TM251-24. Modules must be ordered separately.
