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 19”3U 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.
