Efficiency

Protect Plus S500 can reach the highest AC/AC efficiency levels, up to 95.5 % in online double conversion mode (VFI SS 111). Its flat efficiency curve from 35% of load ensures maximum energy savings at every load percentage. Moreover, with a stable mains power supply and load condition, the UPS can achieve up to 99% efficiency in ECO mode.    

Battery Management

Batteries are electro-chemical devices, which store their charge chemically, as such their performance degrades over time. The Protectplus S500 series offers a Battery Anti-Aging Control (BAAC) that works with the connected battery manufacturer’s requirements. Following a UI characteristic curve, the rectifier charges at a constant current appropriate for the battery type used, to prevent damage from excess overcharging. In addition to the float voltage level, a boost charge can be set, optimizing recharge time for when there is the possibility of consecutive power outages within a short time period. BAAC also reduces the residual ripple current (one of the causes of premature battery failure), as well as protecting the battery from deep discharge damage. An automatic battery temperature compensation charge voltage can also be activated to help increase battery life. 

Dynamic Charging Mode

From 60 kVA power models, Protect Plus S500 also offers a DCM (Dynamic Charging Mode) function: for very long battery autonomy, the UPS can achieve the nominal recharge time required, by increasing the recharge current up to 100 A of the recharging current. This is achieved using an intelligent charging function that can operate when the load is drawing less than the maximum power output of the inverter. An integrated periodic battery testing function tests and monitors battery health, providing advanced warning to guide the application of preventive maintenance.  

Parallel Control System for easy upgrade to connected UPS

The Protect Plus S500 UPS solution offers parallel options for both redundancy and capacity modes, providing the possibility for 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. Up to 6 UPS units (of the same power rating) can be connected in parallel. 

Feature Rich Intelligence

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 system connections, allows for easy installation and future field upgrades. In a parallel configuration, UPS can be added or removed without load disturbance or the need to switch to bypass thanks to the ‘hot’ connection design.

The Smart Parallel function can automatically switch o the UPS when the total load connected can be met by the remaining powered UPS. This is known as “load based shutdown” and maximizes the overall efficiency of the complete system by maintaining the load of each UPS at an optimum level.

The AEG PS Protect Plus S500 can be installed near walls or next to other cabinets as cooling air is expelled through fans on the top of the unit. This design gives the user a significant savings in floor use and makes the Protectplus S500 UPS an ideal solution where space is at a premium. Despite its modern compact design, all critical components are accessible from the front of the unit; this improves accessibility to allow regular maintenance and reduced Mean Time to Repair (MTTR).
