Sentinel Dual

  • Input / Output: 1/1 Phase
  • Rating: 5 – 10 kVA

The new Sentinel Dual is the best solution for powering mission-critical applications and electro-medical devices requiring maximum power reliability.

The flexibility of installation and use (digital display, user-replaceable battery set), as well as the many communication options available, makes the Sentinel Dual suitable for many different applications from IT to security. Up to 3 Sentinel Duals can be operated in parallel in either capacity or N+1 redundant configuration offering increased reliability for a critical system. The Sentinel Dual can be installed as Tower (floor standing) or Rack, ideal for network and server rack applications.

The Sentinel Dual range is available in 5-6-8-10 kVA/kW 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 voltage, form, and frequency. In addition, the input and output filters significantly increase the load’s immunity to mains disturbances and lightning strikes.

Technology and performance: selectable Eco Mode and Smart Active Mode functions. Diagnostics: Standard digital display, RS232 and USB interfaces with PowerShield3 software downloadable, communications slot for connectivity accessories.

Operating Mode (Selectable)Description
ECO

The energy control operation (ECO) mode is an energy-saving mode that can be configured via the LCD or web user interface (WebUI). In ECO mode, when the bypass input voltage is within the ECO voltage range, the static bypass switch turns on, and the bypass supplies power. When the bypass input voltage is out of the ECO voltage range, the UPS transfers from bypass mode to normal mode. In bypass mode or normal mode, the rectifier keeps working and charges the batteries. The ECO mode provides a higher efficiency of up to 99%.

EMERGENCY

The UPS can be selected to function only when the mains power supply fails (emergency only mode).

FREQUENCY CONVERTER

System can be set for 50/60 or 60/50Hz

ON-LINE

Affords MAXIMUM protection to load (default).

SMART ACTIVE

The UPS automatically selects the operating mode based on mains power supply quality.

ConfigurationDescription
Parallel

Up to 3 Sentinel Duals can be operated in parallel in either capacity or N+1 redundant configuration offering increased reliability for a critical system.

Simplified installation

  • Can be installed on the floor (tower version) or in rack mount cabinets (rack version). The display panel can be rotated(using the key supplied)
  • Low noise (<48 dBA): can be installed in any environment thanks to its high frequency switching inverter and PWM load-dependent digitally controlled fan
  • External bypass option for maintenance with interruption-free switching
  • Operation guaranteed up to 40°C (the components are designed for high temperatures and are thus subject to less stress at normal temperatures)
  • Built-in IEC output sockets with thermal protection.

Operating mode selection

Functions can be programmed via software or manually via the front display panel.

  • On line: efficiency up to 95%
  • Eco Mode: to increase efficiency (up to to 98%), allows for the selection of Line Interactive technology (VI) to power low priority loads from the mains supply
  • Smart Active: the UPS automatically decides upon the operating mode (VI or VFI) based on the quality of the mains power supply
  • Emergency: the UPS can be selected to function only when the mains power supply fails (emergency only mode).
  • Frequency converter operation (50 or 60 Hz).

High-quality output voltage

  • Even with non-linear loads (IT loads with a crest factor of up to 3:1)
  • High short circuit current on bypass
  • High overload capacity: 150% by inverter (even with mains failure)
  • Filtered, stabilised and reliable voltage (double conversion on-line technology(VFI compliant with EN62040-3), with filters for the suppression of atmospheric disturbances.
  • Power factor correction: UPS input power factor close to 1 and sinusoidal current uptake.

High battery reliability

  • Automatic and manual battery test
  • Reduced ripple component (detrimental to the batteries) using a low ripple current discharge (LCRD) system
  • Batteries are user replaceable without switching off equipment and without interruption to the load (Hot Swap)
  • Unlimited extendible runtime using matching Battery Boxes
  • The batteries do not cut in during mains failures of <20 ms (high hold up time) or when the input supply is between 184 V to 276 V.

Emergency function

This configuration ensures the operation of those emergency systems that require a continuous, reliable and long-lasting power supply in the event of a mains power failure, such as emergency lighting, fire detection/ extinguishing systems, and alarms. When the mains power supply fails, the inverter begins powering the loads with a progressive start-up (Soft Start) in order to prevent overload.

Battery optimisation

The wide input voltage range and a high hold-up time minimise battery usage and increase efficiency and battery life; for smaller power breaks, energy is drawn from a group of appropriately-sized capacitors.

EnergyShare

10 A configurable IEC output sockets allow for runtime optimisation by programming the switching off of low priority loads on mains failure; alternatively, emergency loads that are normally not powered when mains is present can be activated.
