DPS : Industrial system

DPS provides maximum protection for all mission-critical industrial applications thanks to an exceptional mechanical and electrical design. The DPS operates from 10 to 200kVA and uses an ON-LINE double conversion technology (VFI) with an isolation transformer on the inverter output. Power is constantly supplied to the load by the inverter with a filtered, stabilised and regulated sinusoid wave. The EMI input and output filters considerably increase the load immunity from noise or temporary mains overcurrents.

The DPS may be supplied along with an optional control software and can be remotely controlled through a serial or Ethernet interface.

High flexibility, allowing our equipment to adapt to all system features

The DPS is suitable for a wide range of applications in the most demanding industrial environments. It allows to achieve complex system architectures to ensure maximum power availability with a wide range of accessories and optional. We can supply redundant N+1 or HOT STANDBY configurations. Thanks to the new our DIGITAL TECHNOLOGY, you can choose different alarms with voltage-free contacts, with a wide range of LED indications and accurate digital measurements. Furthermore a graphical display shows measurements, alarms and a one-line diagram to help the operator to better understand the situation. The digital inputs can be customised according to specific customer needs, allowing to take into account special system statuses and to display them on the monitor. The display can store the alarm list and an event history. You can adapt the DPS to the technical specifications. Should you need any particular applications and customised solutions, please contact AUNILEC.

Absolute reliability and performance

To ensure its compatibility with the most demanding applications, the Aunilec DPS system can withstand a high short-circuit current, in order to guarantee the selectivity of the downstream protections. The fully DIGITAL microprocessor logic controls the power conversion, supervises operation, supports the system and modifies the parameters in case of component failure to assure power supply to the load. If the load is highly distorted, the high frequency switching and the DPS loops support the system by keeping THD low. The Aunilec digital UPS units are fitted with a modern IGBT techno-logy and a PWM modulation allowing to obtain a pure sinusoid output wave as required by the strictest standards contained in IEC EN 62040 class VFI-SS-III. Ventilation may be redundant, allowing to keep a rated output load only using one half of the fans. The air flow sensors detect the ventilation drop and immediately trigger an alarm, allowing to replace the damaged fan.Onduleur industriel écran tactile

Battery management system: maximising life

When the system is powered by the mains, the UPS rechar-ges the batteries. In case of mains failure power is supplied to the inverter from the batteries. Efficient battery management, therefore, is essential for the UPS yield in case of emergency. Battery management consists of a set of features designed to ensure excellent yield and prolong the battery life:

  • Double level charging, to optimise the charging currents and reduce the charging time
  • Four automatic charging modes, with different current ma-nagement in compliance with the provisions set forth by the strictest standards
  • Programmable temperature compensation and discharge protection to reduce general battery ageing
  • Manual charging mode for the commissioning of any battery type
  • Intelligent and schedulable battery testing, for the identification of potential battery deterioration and failure
  • The voltage values, the times and the alarm thresholds can be programmed directly by the user through multilevel passwords
  • The UPS may be installed in any distribution system (the rectifier input neutral is not required)

Low consumption levels

Thanks to component sizing, the UPS systems can reach high efficiency levels even with low DC bus voltages. The selectable Line Interactive mode may be used in stable environments to achieve very high efficiency levels (~98%) in case of inverter power supply failure, and when synchronised with the mains it can take on the load in less than 1ms.
