  • Description

    Sentryum is Riello UPS’s third generation of transformerless ONLINE UPS. Delivering outstanding performance and up to 96.5% efficiency in a compact footprint, it’s a proven solution for smaller data centres and similar applications.

    Now available in 10-15-20-30-40 kVA models, choose from 3 different cabinet sizes to maximise your battery autonomy and make the most of your valuable floor space. Designed to handle capacitive loads like blade servers without any reduction in active power.

    Fantastic Flexibility

    Sentryum offers you a choice of power ranges and cabinet sizes, making this versatile series suitable for several mission-critical environments. Select from 3 frames to suit your space and battery requirements:

    Xtend (XTD):

    • 132 cm x 44 cm x 84 cm (H x W x D)
    • 0.25m² footprint
    • 3 internal battery strings – space for 3×40 blocks
    • Optional isolation transformers
    • Available for all versions

    Available as 1-phase/3-phase input, 1-phase output or 3-phase input and output.

    Reliable And Efficient

    Our transformerless UPS delivers unity power (pf 1) and operating efficiency of up to 96.5%, which helps you minimise wasted energy. It features a unique control system that reduces harmonic voltage distortion (<1% at resistive load and < 1.5% at non-linear load). The Sentryum can also handle high overloads (125% for 10 minutes or 150% for 1 minute) and short circuits (270% for 200ms or 150% for 300ms), meaning you won’t have to transfer to bypass to deal with sudden peak loads.

    Scalable Power

    Easily increase your power or battery autonomy by installing up to 8 Sentryum UPS in parallel (3-phase version). Parallel installations operate on a closed-loop system, so your UPS will keep running even if there’s an issue or disruption with your cable connection.

    Enhanced Performance

    Sentryum builds on previous Riello UPS transformerless series such as the Multi Sentry (MST), with an optimised card layout that reduces the number of components, cables, and interconnections. This reduces the amount of installation space your UPS will need and makes it far easier and more cost-effective to maintain.

    Power At Your Fingertips

    Take control with a 5-inch colour touchscreen display panel which clearly shows real-time information and allows you to easily adjust the operating mode. Also features an innovative new LED status indicator that automatically changes colour depending on the current operating mode and UPS status. In-built wheels enable easy manoeuvrability.

    4. IR Thermal Imaging Surveys – Infrared electrical inspection. Infrared electrical testing finds hot, dangerous problems quickly. Infrared electrical inspections find hot spots caused by defects in connections and components.

    Detect system overloads, loose defective components and damaged switchgear. Infrared electrical testing finds hot, dangerous problems quickly. Infrared electrical inspections find hot spots caused by defects in connections and components.

    Infrared thermography is used to find areas of excess heat (caused by increased resistance) so that problems can be corrected before a component fails, causing damage to the component, creating safety hazards and productivity loss. Because increased heating is a sign of failure, infrared is the best diagnostic tool available for finding these hot connections in the early stages of degeneration.
