Battery temperature compensationUsing optional external battery temperature sensors the UPS is capable of optimising the battery chargeroutput to enhance battery life and performance. This is a non-standard feature that must be purchasedseparately. Contact your distributor for details.Redundant control power supply boardThe UPS is equipped with two identical and fully redundant control power supply boards. Each board ispowered by the input a.c. and battery d.c. Therefore, if one of these sources or even if a board fails theUPS continues to operate normally. This feature further enhances the reliability of the system.Single phase outletA 250 Va.c. 5 A single-phase fused outlet is provided on the front panel. This supply is generated fromthe battery, independent of other UPS power circuits, and can be used for ease of testing, commissioning,and servicing. This output is accessible when the cabinet door is open.250VAC 5AFUSEMulti-unit operationUp to four units can be operated in N+X parallel mode to provide additional power or higher reliability. Inthis configuration the load is shared equally between the units.It is also possible to operate with load bus synchronisation (LBS), which allows the load to be transferredseamlessly between two UPS systems. Each system can be a single UPS or a parallel group of units.Multi-unit operation is enabled by: Hardware and firmware built into each UPS, controlled by software settings. Parallel control cables, connected in a ring to enhance reliability. Dual-bus control cables areconnected between any two UPS modules of each bus. The intelligent paralleling logic provides theuser with maximum flexibility. For example, shutting down or starting up UPS units in a parallelsystem can be done in any sequence. Transfers between Normal and Bypass modes of operationare synchronised and self-recovering.The total load of a multi-unit system can be queried from each unit’s LCD display. |
