STW 8000
UPS
Description
Sentinel Tower (STW) protects non-linear loads found in IT systems, telecoms networks and security/safety systems. High-performing three-level inverter delivers unity power factor and 95% operating efficiency.
Compact Design
Whatever the power rating, the STW measures in at a space-saving 25 cm by 69.8 cm by 50 cm (W x D x H), with built-in castors to assist with mobility. Minimal noise disruption as fan speed automatically adjusts according to the current load.
High Battery Reliability
STW features automatic and manual battery testing, while the batteries don’t cut in during temporary mains failures (< 20 msec) or if the input is between 184-276V, which helps to maintain lifespan.
