Description
The APS-RTx PowerLine Flex PL31-10K-P1-B1 is a complete backup power system designed for critical equipment that requires uninterrupted, conditioned power.
The system combines one PL31 FL 10.0k HC 10kVA / 10kW online UPS power module with one PL31-BR20120FL external battery box, providing a ready-to-configure solution for server rooms, communications equipment, banking systems and other critical infrastructure.
Using online double-conversion technology, connected equipment is continuously powered through the UPS inverter, protecting sensitive loads from voltage fluctuations, frequency instability and common utility power disturbances.
With a 1.0 output power factor, the UPS delivers the full 10kW of usable output power from its 10kVA rating.
The UPS uses a 3-phase input / single-phase output architecture, making it particularly suitable for commercial facilities with three-phase electrical supplies but predominantly single-phase critical loads.
The included PL31-BR20120FL battery box contains 20 × 12V 9Ah maintenance-free VRLA batteries, providing approximately 2.16kWh of nominal stored battery energy for backup operation during power outages.
The system can also be expanded in future by adding compatible UPS power modules in parallel or additional battery boxes where higher power capacity or longer backup runtime is required.
