Flexus FT-H 10-40kVA

Flexus is ideal for the protection of critical information and telecommunications networks which cannot run the risk of being powered from a poor quality electrical supply.

The Flexus series is available in 10-12-15-20-30-40kVA three-phase input and output models, with double conversion on-line technology according to the VFI-SS-111 classification, as defined by the IEC EN 62040-3 standard.

It has been designed and manufactured using state-of-the-art technologies in order to deliver maximum protection for critical users, a zero impact on the mains power supply and a high operating efficiency.

The high level of flexibility at the design stage means that there is full compatibility both with three-phase power and with single-phase sources, thus eliminating any critical factors in the connection between UPS and system.

Extending the back-up time
The Flexus FT-H version offers longer autonomy than the FT version, thanks to the possibility to double the number of batteries inside the cabinet (1320X440X850 HxWxD).

Zero impact source
The superior technology of a Flexus allows it be used where the site mains power supply is limited in capacity, or has an on-site generator and/or loads that generate current harmonic problems.
Flexus is designed to have a zero-impact on its upstream power supply (mains or generator):

• Input current distortion < 3%;
• Input power factor 0.99;
• Power walk-in function to guarantee a progressive rectifier start-up;
• Delayed switch-on function, to sequentially restart the UPS when installed as part of a parallel system.

Flexus also act as a filter and phase-shift protection device in respect to its upstream supply, providing protection from any harmonic components or reactive power generated by downstream loads.

High efficiency
High operating efficiency up to 96.5% providing a 50% saving in energy usage per annum compared to traditional UPS products (92%). This exceptional performance can lead to a full initial investment recovery within three years. The efficiency values quoted were tested independently by TÜV Rheinland.

Battery care system
Battery management is one of the fundamentals of UPS management in order to ensure the system can perform in emergencies. The Flexus Battery Care System consists of a number of functions that together guarantee optimum battery performance.
Battery recharge: Flexus is suitable for use with sealed Valve Regulated (VRLA), AGM, GEL and open-vented lead acid batteries, in addition to Nickel-Cadmium. Depending on the battery type used, the recharging functions can include:

• One-level recharge, typical for the most commonly used VRLA AGM batteries;
• Two voltage level recharge according the IU characteristic;
• Charge blocking system to reduce consumption of the electrolyte and further extend the life of VRLA batteries.

Compensation of the recharge voltage according to temperature in order to avoid excessive battery charging currents and potential overheating problems.
Battery Test in order to detect battery performance deterioration or failure.
Protection against deep discharges: during extended low load discharges, the end-of-discharge voltage is increased as recommended by battery manufacturers, to prevent damage to the battery set.
Current Ripple: recharge current ripple (residual AC component) is one of the most common causes of poor battery performance and reduced operating life.
Flexus, with its high-frequency battery-charger, produces negligible current ripple levels and therefore helps to extend operating life.
Wide voltage range: the rectifier can operate from a wide input range (up to 40% at half load), reducing battery usage and helping to extend their operational life.

Maximum reliability and availability
Connect up to 6 units in parallel or N+1 redundancy, even of different power ratings. The UPS continue to operate in parallel even if one of the interconnecting communication cables is disconnected (closed loop).

Flexibility
Flexus is suitable for use in a broad spectrum of applications, thanks to a variety of configurations, accessories and options providing flexibility and a choice of performance levels:

• Suitable for powering capacitive loads, such as blade servers, without any reduction in active power (0.9 lead to 0.9 lag);
• Multiple operating modes: On Line, Eco, Smart Mode and Stand By Off;
• Frequency converter mode;
• Configurable Power Share connections to ensure backup for the most critical loads or programmed to operate only when mains power fails;
• Cold Start facility that starts the UPS even when it is not connected to the mains;
• Optional temperature sensor for external battery cabinets, to assist the recharge voltage compensation;
• Additional battery chargers to optimise recharge times;
• Optional dual input to mains power supply;
• Isolation transformer options to vary neutral connectivity in the event of separate power sources or for galvanic isolation input and output;
• Battery cabinets of various sizes and capacities to ensure prolonged runtime.

Advancec communication
Flexus is equipped with a graphic display that provides information, measures, states and alarms regarding the UPS in 5 different languages:

• Advanced, multi-platform communication for all operating systems and network environments: Watch&Save 3000 monitoring and shut-down software included, for Windows 2008, Vista, 2003, XP; Mac OS X, Linux, Novell and most popular Unix operating systems;
• Compatible with the TeleNetGuard remote service monitoring system;
• RS232 or USB serial port;
• 3 slots for the installation of optional communication accessories such as network adapters and volt-free contacts;
• REPO (Remote Emergency Power Off) with which to power down the UPS through a remote emergency pushbutton;
• Input for connection of the auxiliary contact of an external manual bypass;
• Input for synchronisation from an external source;
• Graphic mimic panel display for remote connection.
