Off-grid DC/AC inverter STM250

sine wavefor industrial applicationsmodular

STM250 is a sub-rack inverter system integrating TM250 inverter module and TJ20 module. It is a truly redundant system offering functions of pure sine wave inverter, bypass transfer switch and monitor into one 193U sub-rack. Single module is hot plug design which make the maintenance an easy job without interruption to your critical load. For 100Vac/110Vac/120Vac , max 4KVA is available.
