Product Description

The Sentinel Tower UPS 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. The UPS is available in 4 sizes - single phase (1/1) in 5 and 6kVA forms and single phase or 3 phase input option (1/1, 3/1) for the 8 and 10kVA variants.

Parallel configuration of up to 3 units (2+1) for a redundant or power parallel system. The UPS continue to operate in parallel even if the connection cable is interrupted (Closed Loop).

Space saving is offered through the compact design of the UPS. Whatever the power rating, the STW measures in at just 250mm by 698mm by 5600mm (W x D x H),

Minimal noise disruption as the fan speed automatically adjusts according to the current load.

High battery reliability is featured through 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.

Runtime expandability is an option through connecting battery extension packs to increase UPS runtime. In addition to the standard units, the Sentinel Tower range includes ER versions with no internal batteries and more powerful controlled battery chargers for longer runtimes.

Simplified Installation through the UPS being installed on a single-phase or three-phase distribution network (STW 8000 and STW 10000). There is one output terminal board, plus 2 x IEC C13 sockets for powering local consumers (computers, devices, etc.). Simplified positioning is delivered via built-in castors.
