More power in compact footprint

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.

Delivering more real power in a compact footprint, the Sentinel Tower (STW) series is a proven performer across a variety of applications, including blade servers, safety systems, and telecommunications networks.

Choice of 5-6-8-10 kVA power ratings, with the latter 2 suitable for use on three-phase distribution networks. Designed to deal with non-linear loads, delivers quality power (pf 1) at high efficiency (up to 95%).

Proven Performance

3-level inverter helps deliver unity output power factor (kVA = kW) and achieve up to 95% efficiency in ONLINE mode, reducing unnecessary energy waste.

Designed to handle non-linear loads like blade servers and has high short circuit and overload capacity.

Scalable Power

You can parallel up to 3 STWs together to increase capacity or ensure (2+1) redundancy. Parallel installations operate on a closed loop, meaning that they carry on running even if there’s an issue with the connection cables.

Complete Control

Revamped custom-designed LCD display panel shows crucial operating data, alarms, and statuses such as voltage, remaining battery, and current load. Easily adjust operating modes at the simple push of a button.

Compact Footprint

Whatever the power rating, the STW measures in at a compact 25 cm by 69.8 cm by 50 cm (W x D x H), with built-in castors assisting with mobility.

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

High Battery Reliability

For applications needing several hours’ autonomy, choose extended runtime versions (6 kVA and 10 kVA models) fitted with 6A chargers and connected to external battery boxes.
