HE 10, 15 & 20 kVA UPS system, 3ph input - 3ph output

The UPS system HE combines low input THD with almost unity power factor, all these features in a very small box and easy to maintain! The uninterruptible power supply uses a modern input IGBT rectifier and Power Factor Control (PFC) technology capable of keeping the input current Total Harmonic Distortion (THDi) at a very low level (<3 %), as well as keeping the input Power Factor very close to unit (0.99), even when only small loads are applied. The main benefits to be gained are that the UPS is compatible with almost any input source, including generator set. Because the HE UPS system works so efficiently, benefits can be gained in reduced cable sizes and dramatically reduced running costs.

Reduced cost of ownership through efficiency and compactness

The UPS AEG HE has a new Wise ECO function which enables a total operating efficiency of between 93 % and 98 %. This mode, referred to as “Intelligent ECO mode”, significantly reduces the utility costs associated with operating a device of this type. Moreover, this increase in efficiency results in the production of less waste heat, minimizing cooling / air-conditioning costs. This represents a double saving to the energy conscious user. The Wise ECO function uses continual monitoring techniques to review the input characteristics of the supply. This means that if the supply line drops or fluctuates outside of acceptable conditions the UPS uses the internal inverter to support the load. This is achieved through a fast, fully static transition from VFD to VFI mode

Triple Intelligence

If the application requires extremely flexible and reliable UPS protection, the AEG HE is ideal. It delivers advanced features based on state-of-the-art total digital control. This control incorporates dual DSP (Digital Signal Processing) and μC (Micro controller) technologies. Well-designed control architecture and a simplified two-stage power conversion topology ensure that it is almost impossible to drop the load even if a fault occurs! The status of the most critical components is constantly monitored. This allows predictive maintenance and avoids unexpected breakdowns. AEG HE’s working state can be easily monitored by any Building Management System and via LAN / WAN.

Parallel systems with “hot swap” modularity

The AEG HE UPS solution offers parallel options in both redundancy and capacity modes, providing the possibility for both extra system resilience and increased capacity. The parallel control circuitry associated with these units is fully digital and acts on both active and reactive power on each of the three output phases. This allows accurate load current sharing among the UPS units even during transient conditions. Parallel control is distributed between all units and communication is achieved through the use of a CAN bus connection loop. This has the effect of producing a highly reliable system with “no single points of failure”. Intelligent design of the system connections allow for easy installation and easy future upgrades, this allows for upgrading the field without difficulty. In the modular arrangement, units can be added or removed “hot” without load disturbances or the need to switch to bypass. Smart Parallel functions facilitate the automatic switching off of units where the total power requirements of the load is provided by fewer than the total number of UPS units attached. This is commonly known as “load based shutdown” and maximizes the efficiency of the complete system by keeping the load on each module at an optimum level. Two independent paralleled systems can be synchronized (Sync Control) in order to feed downstream STS’ for seamless transfers.

Protection for every application

VFI online double conversion topology in this equipment offers built-in inverter galvanic protection, completely isolating the output power from all input power anomalies, delivering fully conditioned pure sine-wave output. The AEG HE unit is designed to provide excellent output voltages suited to very demanding applications with either 100 % step load, unbalanced, non-linear or modern IT loads. It also provides exceptional performance: with a power factor of up to 0.9 (lagging or leading), there is no requirement to de-rate the unit.

Accurate Battery Management

Batteries are electro-chemical devices and as such their performance gradually decreases over time. To off-set battery degradation, the AEG HE incorporates a battery management function, ABM (Advanced Battery Management), operating in accordance with the battery manufacturers’ specifications. Following a UI battery characteristic curve the charger uses a constant current appropriate for the battery type, this control prevents detrimental over charging. In addition to the float voltage a boost charge can be set: this feature optimizes the recharge time, in the event of consecutive power outages over a short period of time, as it is vital that as much energy can be restored to the batteries whilst the power is on. ABM also reduces the residual current ripple which is one of the main causes of premature battery wear; the same control circuit is employed to protect batteries against damaging deep discharges. Automatic temperature compensation can be incorporated resulting in the batteries being charged under correct thermal conditions. This feature greatly extends battery life. Further an integrated periodical function is also included which tests and monitors battery health providing advance notification of potential battery problems.

Easy installation, operation and maintenance

The AEG HE has a high power to space ratio, this results in a very small footprint allowing the client to achieve maximum power in a relatively small space. The unit is fitted with wheels making it easy to move in and out of position. The AEG HE series is based on light power modules which can be withdrawn from the front of the machine. This feature makes for incredibly easy servicing and dramatically reduces any potential down time.
