The Sentinel Tower 8000VA UPS is a high-efficiency online double-conversion power protection system designed for critical IT, telecom, and industrial environments. Delivering stable, clean energy with unity power factor performance, it ensures continuous operation for demanding non-linear loads such as servers, network infrastructure, and security systems.
The Sentinel Tower 8000VA is engineered to deliver stable and efficient power for always-on environments. With up to 95% efficiency in ONLINE mode, it reduces energy loss while maintaining continuous double-conversion protection for sensitive systems.
This UPS supports parallel operation of up to three units, enabling increased capacity or redundancy. This makes it ideal for expanding IT infrastructures where reliability and scalability are essential.
Designed to handle non-linear loads, the system is well-suited for blade servers, telecom networks, and security installations. Its robust electrical design ensures stable performance even under complex load conditions.
The load-controlled fan system adjusts automatically based on demand, maintaining noise levels below 45 dBA. This ensures quiet operation without compromising thermal performance.
Users can switch between ONLINE, ECO, and SMART ACTIVE modes at the push of a button, allowing optimisation between energy efficiency, protection level, and operational requirements.
Despite its high power capacity, the Sentinel Tower maintains a compact footprint with integrated mobility features. This makes it suitable for constrained technical spaces while still delivering enterprise-grade performance.
The system includes advanced battery management with automatic and manual testing. It also avoids unnecessary battery discharge during minor voltage fluctuations, helping extend overall battery lifespan and 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.
