Sentinel Dual SDU

Мощност 4 - 10 kVA
Sentinel Dual е най-доброто решение за захранване на критично важни приложения и електромедицински устройства, изискващи максимална надеждност на електрозахранването. Серията Sentinel Dual се предлага в модели с мощност 4 kVA и 5-6-8-10 kVA/kW с технология за двойна конверсия ON LINE (VFI): натоварването се захранва непрекъснато от инвертора, който осигурява синусоидално напрежение, филтрирано и стабилизирано по отношение на напрежение, форма и честота. Намалете консумацията на електроенергия с помощта на режимите ECO и SMART ACTIVE. Дайте приоритет на най-критичните си натоварвания с гнездата EnergyShare, които позволяват лесно разпределяне на натоварването. Вентилаторите с управление според натоварването свеждат до минимум шума (<48 dBA).

Акценти

  • Power factor 1 kW = kVA (from SDU 5000)
  • Parallelable up to 3 units
  • Simplified installation
  • Operating mode selection
  • High quality output voltage
  • High battery reliability

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 supplied key);
  • 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;
  • STANDBY OFF: 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.

Other features

  • Selectable output voltage (220/230/240 V);
  • Dual input supplies configuration (SDU 10000 DI and SDU 10000 DI ER);
  • Auto-restart when mains power is restored (programmable via software);
  • Bypass on: when the machine is switched off, it automatically goes into bypass and battery charge mode;
  • Minimum load switch-off;
  • Low battery warning;
  • Start up delay;
  • Total microprocessor and DSP control;
  • Automatic bypass without interruption;
  • Use of custom power modules;
  • Status, measurements and alarms available on standard backlit display;
  • UPS digital updating (flash memory upgradeable);
  • Output sockets protected with resettable thermal switch;
  • Back-feed protection standard: to prevent energy from being fed back to the network;
  • Manual switching to bypass.
