Aunilec DSP Power Solutions - 1

Digital static UPS unit 1Ph or 3Ph Main features: Double rectifier 125 Vdc 1250A Double inverter 125 Vdc 100KVA Change over switchboard installed in Hassi R Mell Solar Plant (Algerian desert) 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. - Clean and stable DC on battery with ripple voltage peakpeak value <1% - Pure VFI-SS-III output sinusoid wave as provided for by the IEC/CEI EN 62040 standards - Redundant fan system with temperature and air flow control - 5 automatic charging modes - Manual charging mode for open cup batteries - Adjustable times and alarm thresholds - Temperature compensation programmable on the charging voltage to extend the battery life. - Double digital microprocessor control (DSP + PLD) for rectifier and inverter, ensuring maximum reliability - Full optical isolation on all the logic and interface cards. - Modbus communication interface through RS232 or RS485 port. - Ethernet connectivity. - Optional FALCON battery control system. - Separate DSP for rectifier and inverter to improve reliability. Absolute reliability and performance DSP board with Modbus communications Touch screen display 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 technology 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.

Battery management system: maximising life 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. When the system is powered by the mains, the UPS recharges the batteries. In case of mains failure power is supplied to the inverter from the batteries. Efficient battery management,...
