1. Product Overview

The GT Rack Series 10–60kVA is a three-phase online double-conversion UPS developed by GOTTOGPOWER (ANHUI) CO., LTD that refuses to commit to a single form factor. Every model mounts in a standard 19-inch rack — 10–20kVA in 3U (130mm), 30–60kVA in 4U (175mm) — and every model also stands vertically as a tower UPS using the same chassis. The choice is made at installation time, not at the factory, giving facilities teams the flexibility to deploy whichever configuration fits the space without stocking two separate product lines.

Six long-run (RL) models cover 10kVA to 60kVA, all supporting 3P/3P, 3P/1P, and 1P/1P input/output topologies within a single unit. That topology flexibility matters: a site that starts with a three-phase input feeding three-phase servers (3P/3P) can reconfigure the same UPS to feed single-phase distribution boards (3P/1P) if the load mix changes — without replacing the UPS hardware. The 60kVA model fits 60kW of three-phase online protection into 4U (175mm), a power density that three-phase tower UPS units of the same rating cannot match.

2. Key Features

• Rack or Tower — One Unit, Two Deployment Options: The GT Rack chassis ships ready for both orientations. Rack brackets secure it horizontally in any standard 19-inch cabinet; vertical feet flip it into a freestanding tower. No conversion kit, no separate SKU. For IT teams managing mixed environments — some equipment racks, some open floor space — this single inventory item covers both scenarios.
• 60kW in 4U — Three-Phase Power Density at Rack Scale: Fitting 60kW of three-phase online UPS protection into four rack units is a meaningful engineering achievement. It means a 42U rack can carry a fully redundant three-phase UPS in the bottom four units and fill the remaining 38U with protected load — a configuration that a floor-standing three-phase tower UPS cannot enable because it occupies floor space rather than rack height.
• 3P/3P, 3P/1P, 1P/1P — All Three Topologies in One Platform: Most rack-format three-phase UPS products support only 3P/3P. The GT Rack supports all three output configurations, making it the appropriate choice for mixed-topology sites: three-phase server infrastructure (3P/3P), single-phase distribution from a three-phase feed (3P/1P), or purely single-phase environments (1P/1P) — all served by the same hardware.
• 7-Inch IoT Touch LCD — Three-Phase UPS Management in the Rack: The 7-inch color touch LCD with IoT connectivity provides the same rich, real-time UPS monitoring interface found on large modular UPS systems, now accessible from the front panel of a rack-mounted three-phase unit. Remote IoT integration means UPS data flows to building management systems and DCIM platforms without requiring a separate monitoring server.
• Battery Configuration Split by Power Class — Optimized per Model: GT010RL uses a ±120VDC battery bus (20–50 cells, Max 50% * Pout charging) appropriate for its power class; GT015RL through GT060RL step up to ±240VDC (30–50 cells, Max 20% * Pout). This split avoids over-specifying the battery system for smaller models and under-specifying it for larger ones — each model uses the battery architecture that best matches its power rating and runtime requirements.
• Wide Storage Temperature −40°C to +70°C: The −40°C lower storage temperature limit is significantly wider than most UPS specifications. For units deployed in unheated storage facilities, outdoor enclosures, or cold-climate sites where equipment may sit unpowered through winter, this range prevents battery and component damage during storage without requiring climate-controlled warehousing.
• ≥96% Efficiency with Full Three-Phase Output Flexibility: Across all six models and all three supported topologies, efficiency reaches ≥96% — ensuring that the flexibility to switch between 3P/3P, 3P/1P, and 1P/1P does not come at the cost of higher conversion losses or increased rack thermal load.

3. Typical Applications

The GT Rack Series addresses the specific gap where three-phase UPS protection needs to be either rack-mounted or tower-deployed, with topology flexibility to match changing load configurations:

• Mixed-Format Data Halls — Rack and Tower in the Same Deployment: In data halls where some rows use populated equipment racks and other areas have open floor space, the GT Rack's dual-form-factor capability lets a single stocked model serve both, simplifying procurement, sparing, and field team training.
• High-Density Three-Phase Rack Deployments — 60kW in 4U: Hyperconverged infrastructure racks, high-density storage arrays, and GPU compute racks that draw 40–60kW of three-phase power can now have their UPS inside the rack rather than beside it — keeping cable runs short and the three-phase distribution architecture clean.
• Topology-Agnostic Enterprise Installations: Enterprise deployments that mix three-phase server infrastructure with single-phase workstation clusters or single-phase distribution panels can use the same GT Rack model configured appropriately for each zone, rather than stocking separate three-phase and single-phase UPS products.
• Edge Data Centers & Remote Sites: The −40°C storage temperature, wide 40–70Hz input frequency range, and dual rack/tower deployment options make the GT Rack particularly suited for edge data centers in extreme climates, remote industrial sites, and locations served by generators with non-standard frequency characteristics.
• Healthcare Campus Equipment Rooms — Three-Phase Rack Protection: Hospital equipment rooms that feed both three-phase imaging systems and single-phase clinical workstations from the same UPS can use the GT Rack in 3P/3P or 3P/1P configuration as the load mix evolves, without replacing hardware.
• Broadcast & Media Infrastructure Racks — Three-Phase Density Without Tower Footprint: Live broadcast production facilities and media distribution infrastructure increasingly use high-density rack configurations. The GT Rack brings three-phase online protection into the rack itself, eliminating the floor-standing tower UPS that would otherwise occupy valuable production space.

4. Technical Specifications

Note: All models are long-run (RL) with external battery. GT010RL–GT020RL are 3U (130mm); GT030RL–GT060RL are 4U (175mm). Battery voltage and charging capacity differ between GT010RL and the remaining five models as shown below.

5. Certifications & Compliance

The GT Rack Series carries a full IEC certification suite covering both safety and electromagnetic compatibility — the same certification scope as the GT Tower Series, confirming that the rack and tower form factors of the GT product family share equivalent compliance credentials:

• UPS Safety Standard: IEC 62040-1, IEC 60950-1
• UPS EMC Standard: IEC 62040-2
• ESD Immunity: IEC 61000-4-2
• Radiated Susceptibility: IEC 61000-4-3
• Electrical Fast Transient / Burst: IEC 61000-4-4
• Surge Immunity: IEC 61000-4-5

6. Interfaces & Optional Accessories

Standard Interfaces

USB, RS232, RS485, and Dry Contact ship as standard on all GT Rack models — a broader standard interface set than most rack UPS products in this class. RS485 in particular enables direct Modbus RTU integration with data center BMS and row-level power monitoring infrastructure without requiring an optional add-in card, which is relevant for three-phase deployments where BMS integration is more commonly specified than in single-phase rack environments.

Optional Accessories

• SNMP Card — adds IP-based UPS monitoring via SNMP, enabling the GT Rack to report three-phase input measurements, per-phase output loading, battery state, and alarms to any DCIM or NMS platform that can poll a standard UPS MIB.
• Parallel Kit — enables N+1 redundant parallel operation of multiple GT Rack units for scalable three-phase UPS capacity expansion, allowing the installation to grow with the load without replacing individual units.
• APP/Wi-Fi/Bluetooth — wireless access to UPS parameters and alarms via mobile device, useful for commissioning and walkaround checks in large facilities where the rack may not be easily accessible from a fixed monitoring workstation.
