The Sentinel Tower UPS is a high-performance power protection system designed for critical IT environments, telecom networks, and security infrastructure. Built to deliver stable, efficient, and scalable backup power, it ensures continuous operation for demanding non-linear loads while maintaining compact dimensions and low energy waste.
The Sentinel Tower is engineered to maximise efficiency while maintaining consistent power delivery. With up to 95% efficiency in ONLINE mode, it reduces unnecessary energy loss, making it suitable for always-on environments where uptime and operational cost control are essential.
This UPS system supports parallel configuration of up to three units, allowing organisations to increase capacity or build redundancy into their power infrastructure. This makes it suitable for growing IT environments that require flexible expansion without replacing existing hardware.
Designed specifically for non-linear loads, the Sentinel Tower performs reliably in environments such as server rooms, telecom installations, and security systems. Its three-level inverter ensures stable output even under complex electrical demands.
The system incorporates load-controlled fan technology that automatically adjusts speed based on demand. This reduces unnecessary noise during low loads while maintaining effective cooling when performance requirements increase, keeping operational sound levels low.
Users can switch between ONLINE, ECO, and SMART ACTIVE modes directly from the control panel. This flexibility allows optimisation between energy efficiency, protection level, and operational requirements depending on the environment.
Despite its high power capacity, the Sentinel Tower maintains a compact footprint suitable for constrained technical spaces. Built-in castors improve mobility, making installation and repositioning easier within server rooms or office environments.
The system incorporates advanced battery management features including automatic and manual testing. It also avoids unnecessary battery discharge during minor mains fluctuations, helping to extend overall battery lifespan and improve long-term reliability.
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%).
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.
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.
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.
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.
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.
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.
