Low consumption
As well as the on-line operating mode, Sentry Multistandard can operate in:
- Economy Mode The UPS uses Line Interactive technology: the load is powered from the mains; the energy consumption is reduced with a subsequent improvement in efficiency (98%).
- Smart Active Mode The UPS automatically selects On Line or Line Interactive operating mode according to the quality of the mains supply, by monitoring the number, frequency and type of disturbances at the mains power input.
- Stand-by-Off (back-up unit)
Expandability
The units can be connected in parallel up to 8 units to increase power availability or redundancy. The single module or the system can be expanded at any time following the power demand without any influence on the initial investment. Thanks to the peculiarity of the ÅgHot System ExpansionÅh feature, the additional unit can be connected in parallel while the other units are on-line and supplying regular power to the load. The new UPS is on-line and will receive the updated information automatically.
High reliability
The digital control of the appliance considerably improves its reliability, since a reduction in electronic components lowers the likelihood of breakdowns. The parallel connection of the UPS up to 8 units exponentially increases the reliability of the system. The parallel connection system has 2 levels of redundancy: in the event both redundant cables are lost only the relevant module will be disconnected from the output bus bar, while the other modules supply power to the load.
Operating flexibility
Sentry Multistandard is a UPS with On- Line double conversion technology that can also operate in Line Interactive mode (Economy Mode). It can handle the two architectures autonomously through the Smart Active function. The Stand-By-Off function can be used to transform the UPS into a back-up unit to supply power for emergency lighting. Sentry Multistandard can also be used as a Frequency Converter, 50/60Hz or vice versa.
Maximum battery care
Temperature is the greatest threat to batteries; for this reason, Sentry Multistandard monitors the temperature of the battery and thereby controls the battery charging voltage. An automatic battery test periodically checks the efficiency of the batteries. The batteries are not used during micro-interruptions (40 ms), since the required energy is drawn from a group of capacitors (BATTERY SAVING). This system extends the life of the batteries. The Sentry Multistandard range also includes deep discharge protection feature.
Maximum safety for personnel
The back feed protection device prevents any voltage back feed in the upstream distribution board, thus ensuring the safety of the maintenance personnel.
Advanced communication
The unit comes with EPIÅfs Watch & Save software as a standard feature. The software displays the most important information such as the input and output voltage, the load applied, the remaining back-up time, etc., in the form of bar graphs. It is able to provide information even in the event of a failure, to support the fault diagnostics. Watch & Save software can be used to program the automatic shutdown of all open systems in the event of a prolonged black out. The UPS also contains the following hardware interfaces:
- RS232 serial port,
- Dry contacts,
- EPO (Emergency Power Off) contact for UPS shutdown using the remote emergency button.
Mimic panel
The mimic panel allows easy and intuitive operation of the UPS. It gives access to the most important parameters: status and alarms, control commands, input, output, battery measurements (power, current, voltage, frequency and temperature) and settings. The Sentry Multistandard diagnostics system includes up to 128 alarms or messages allowing precise and detailed identification of any event.
Low Input Harmonic Distortion
The Power Factor Correction (PFC), standard on all models, guarantees the input power factor level to 0,95 for any load percentages so that it is ideal in conjunction with Motor Generator or in installations with other sensitive loads. Sentry Multistandard is also available with built-in Active Filter designed to reduce the level of THDi to less than 4% and to increase the input power factor up to 0,99. Other benefits:
- Advanced technologies: Active Filter is based on the IGBTÅfs Technologies controlled by the Digital Signal Processor (DSP). DSP instantly monitors and controls the input current absorbed by the UPS in order to eliminate the unlike harmonics and maintain the THDi less than 4 %.
- Maximum efficiency: thanks to the Active Filter, Multistandard has low input harmonics even at low loads connected at the output.
- Compact size: no addition footprint is required because the Active Filter is fitted inside the base Multistandard unit.
- Reduction of the neutral current: less harmonics at the Multistandard input reduces the neutral cable size and consequently the installation costs.
- Maximum reliability: thanks to this design solution any failure of the optional Active Filter has no influence on the power supplied to the load; the only consequence is the increase of current harmonics level rejected to the mains. MAXIMUM RELIABILTY FOR THE LOAD.
Maximum flexibility
The UPS can be connected to a single phase or three phase mains supply (except for 6000 VA). This can be carried out directly at the installation site. The UPS can be programmed to operate as a frequency converter with batteries.
