1. Product Overview

The GTS-Pro Tower Series 6–20kVA is a professional-grade, dual-topology tower UPS developed by GOTTOGPOWER (ANHUI) CO., LTD, unifying two distinct sub-series under a single product family: the GSS sub-series accepting single-phase (L-N) input, and the GTS sub-series accepting three-phase (L-L) input — both delivering Online Double Conversion (3P/1P, 1P/1P) single-phase output protection across a 6–20kVA power range. This deliberate dual-input architecture makes the GTS-Pro the most versatile tower UPS in the GOTTOGPOWER lineup, purpose-built for deployments where both single-phase office environments and three-phase infrastructure feeds must be served by the same UPS platform.

At the heart of the GTS-Pro is a high-speed DSP control engine governing all power conversion and protection functions in real time, paired with a 4.3-inch color touchscreen for immediate, intuitive on-device UPS management — a compact, operator-friendly interface that sets it apart from products relying on LED indicators or larger, less portable display panels. Digital charging with active battery monitoring, auto fault waveform recording, and an optional 12A fast charger upgrade complete a feature set that prioritizes both operational transparency and long battery service life.

2. Key Features

• Dual Input Architecture — Single-Phase (L-N) & Three-Phase (L-L) Sub-Series in One Family: The GTS-Pro uniquely spans two input configurations within a single product range: GSS models accept 110–288VAC (L-N) single-phase input for office and distributed IT deployments, while GTS models accept 190–499VAC (L-L) three-phase input for infrastructure-fed installations — providing procurement and operational simplicity across diverse site power environments.
• 4.3-Inch Color Touchscreen — Compact Professional UPS Interface: Unlike the larger 7-inch or 10-inch displays found on modular UPS systems, the GTS-Pro's 4.3-inch color touch panel delivers a focused, operator-friendly interface specifically sized for tower UPS deployments where screen real estate is secondary to quick status checks and parameter adjustment — ideal for IT staff without specialist power engineering backgrounds.
• High-Speed DSP Control — Real-Time Performance & Protection: A dedicated high-speed DSP processor governs every aspect of UPS operation — rectification, inversion, battery charging, and protection response — enabling sub-cycle fault detection, tighter output regulation (±1%), and faster protective switching than conventional microcontroller-based UPS designs.
• Digital Charging with Active Battery Monitoring: The GTS-Pro's digital charging system continuously monitors individual battery parameters during charging and operation, adapting charge current to battery condition in real time — extending battery service life, preventing overcharge damage, and providing early warning of battery health degradation before it affects UPS availability.
• Auto Fault Waveform Recording — Field-Ready Diagnostics: Automatically captures and stores electrical waveforms at the moment of fault occurrence, giving maintenance engineers the raw data needed for accurate post-event analysis without requiring external power quality meters or data loggers on site.
• Optional 12A Fast Charger — Rapid Battery Recovery: An optional 12A charger module upgrade (vs the standard 8A) significantly accelerates battery recharge after a discharge event — minimizing the window during which the UPS operates with reduced backup reserve and maximizing overall UPS system availability.
• Optional Maintenance Bypass Switch — Zero-Downtime Servicing: Available as an option (unlike the standard-integrated bypass on some competing products), the maintenance bypass switch enables safe UPS module servicing, battery inspection, and firmware updates without interrupting power to critical connected loads.
• 98% ECO Mode Efficiency with 0ms INV-to-BYP Transfer: ECO mode delivers 98% efficiency for maximum energy savings in stable grid environments, while the 0ms inverter-to-bypass transfer ensures that ECO mode operation never compromises load protection during mode transitions.

3. Typical Applications

The GTS-Pro Tower Series addresses a specific gap in the UPS market: deployments that need professional-grade features, dual input topology flexibility, and compact touchscreen management in a tower form factor:

• Mixed-Input Enterprise Deployments — Sites with both single-phase office power feeds and three-phase infrastructure risers can standardize on a single GTS-Pro UPS platform, simplifying procurement, spares management, and operator training.
• Medium-Scale Server Room & IT Equipment UPS — Professional 6–20kVA single-phase output UPS for SME server rooms, virtualization stacks, NAS/SAN infrastructure, and enterprise network switching equipment.
• Industrial Control & Process Automation UPS — 3P/1P input configuration with half-wave load adaptation for PLCs, SCADA terminals, process control computers, and factory automation equipment on three-phase power feeds.
• Healthcare & Clinical IT UPS — 0ms transfer time and active battery monitoring for hospital server rooms, clinical workstations, patient data management systems, and medical device power protection.
• Finance & Banking Branch Infrastructure UPS — High-reliability, touchscreen-managed UPS for branch office servers, trading terminals, and ATM back-office systems with optional maintenance bypass for zero-downtime servicing.
• Education & Research Computing UPS — Scalable tower UPS with parallel kit option for university server rooms, research computing clusters, and campus IT infrastructure requiring capacity expansion without full UPS replacement.
• Broadcast & Media Production UPS — Auto fault waveform recording and digital battery monitoring for broadcast control equipment, NLE workstations, and media server infrastructure where power event forensics are operationally valuable.

4. Technical Specifications

Note: B = Built-in battery variant; L = Long-run (external battery) variant. Both sub-series share identical output specifications and protection features.

5. Certifications & Compliance

The GTS-Pro Tower Series is designed and tested against IEC 62040-3, the international UPS performance classification standard covering output performance categories, waveform distortion limits, and transfer time verification. All output THDu values (≤1% linear, ≤5% non-linear) are measured and reported in accordance with IEC 62040-3 test conditions at rated load.

6. Interfaces & Optional Accessories

Standard Interfaces

All seven GTS-Pro models ship standard with both RS232 and RS485 ports — RS232 for direct PC-based UPS management and graceful shutdown software, and RS485 for Modbus RTU integration with building management systems, industrial SCADA, and DCIM platforms over longer cable runs.

Optional Accessories

• SNMP Card — adds TCP/IP network monitoring via SNMP v1/v2/v3, enabling the GTS-Pro to report status, alarms, and measurements to any NMS or DCIM platform without a dedicated monitoring PC.
• Dry Contact Board — provides isolated relay outputs for signaling generator start/stop, building alarm systems, or BMS event triggers independently of the RS232/RS485 data ports.
• Parallel Kit — links two or more GTS-Pro units for N+1 redundancy or capacity stacking, giving the installation a growth path without replacing the existing UPS hardware.
• 12A Charger Module — upgrades the standard charging circuit to 12A, cutting battery recharge time after a deep discharge and shrinking the post-outage vulnerability window for sites with frequent or prolonged power events.
• Maintenance Bypass Switch — routes mains power directly to the load, allowing the UPS inverter and battery to be fully isolated for safe inspection, replacement, or firmware work while the load stays live.
• APP/Wi-Fi/Bluetooth — pairs the GTS-Pro with a smartphone or tablet for wireless parameter checks and alarm acknowledgment without opening a laptop or walking to a monitoring station.
