Sentinel Tower STW

Product catalog summary
Overview: The Sentinel Tower is a UPS (Uninterruptible Power Supply) designed to protect mission-critical systems such as safety devices, telecommunications equipment, and IT systems. It offers high efficiency, reliability, and advanced communication capabilities.
Specifications: The Sentinel Tower series includes models with power ratings of 5-6 kVA/kW for single/single-phase and 8-10 kVA/kW for single/three-phase input with single-phase output. It features ON LINE double conversion technology, ensuring continuous power supply with a sinusoidal voltage output.
Key Features:
  • High efficiency up to 95% in ON LINE mode and 98% in ECO mode.
  • Power factor of 1, delivering more real output power.
  • Parallelable up to 3 units for redundancy or increased power.
  • Selectable operating modes: ON LINE, ECO, SMART ACTIVE, STANDBY OFF, and Frequency Converter.
  • High-quality output voltage with low distortion and high overload capacity.
  • Advanced diagnostics and communication interfaces including RS232, USB, and optional communication boards.
Reliability and Installation: The UPS is designed for high reliability with microprocessor and DSP control, static and manual bypass, and high-temperature tolerance. It can be installed on single-phase or three-phase networks and includes features for simplified installation and battery management.
Battery Management: The system includes automatic and manual battery tests, extendable runtime with battery cabinets, and a high hold-up time to prevent battery discharge during short power interruptions.
Standards and Compliance: The Sentinel Tower complies with European directives for low voltage and electromagnetic compatibility, as well as safety and EMC standards. It is RoHS compliant and classified as VFI-SS-111 according to IEC 62040-3.
Additional Features: The UPS offers low noise operation, auto-restart, backfeed protection, and digital updates. It supports advanced multi-platform communications and remote monitoring.

Sentinel Tower STW-1

DIGITAL LIVING Sentinel Tower Energy Share HIGHLIGHTS • Small footprint • Power factor 1 • High efficiency 95% • Parallelable up to 3 units • 3 level inverter • Maintenance bypass • High quality output voltage Sentinel Tower is the ideal solution for protecting mission critical systems such as safety devices, telecommunications equipment and IT systems to ensure maximum power reliability. Sentinel Tower is designed and built using state-of-the-art technology and components to provide maximum protection to the powered loads with no impact on downstream systems and optimised energy savings. The series includes 5-6 kVA/kW single/single-phase and 8-10 kVA/kW single/threephase input single-phase output models with ON LINE double conversion technology (VFI): the load is powered continuously by the inverter which supplies a sinusoidal voltage, filtered and stabilised in terms of form and frequency. Input and output filters provide significant further immunity from mains disturbances and lightning strikes. In terms of technology and performance, Sentinel Tower is one of the best UPS available on the market today: three-level inverter to achieve 95% efficiency, output power factor 1 to Increase in efficiency of system and devices and reduce power system losses. Selectable ECO Mode and SMART ACTIVE Mode functions; new custom diagnostics LCD display, RS232 and USB interfaces with PowerShield3 software, ESD input, interface slot with optio
