The APS-RTx PowerLine Flex PL31-20K-P2-B1-KIT<\/strong> is a scalable 20kVA \/ 20kW online UPS system<\/strong> comprising 2 parallel PL31 FL 10.0k HC power modules<\/strong> and 1 PL31-BR20120FL external battery box<\/strong>.<\/p>\n

The two 10kVA \/ 10kW power modules operate in parallel<\/strong>, providing a combined system capacity of 20kVA \/ 20kW<\/strong> while maintaining the flexibility to expand the installation further as power requirements grow.<\/p>\n

Using online double-conversion technology<\/strong>, connected equipment is continuously supplied through the UPS inverter, providing stable, conditioned power and zero transfer time during utility failure<\/strong>.<\/p>\n

Each power module delivers a 1.0 output power factor<\/strong>, allowing the complete system to provide up to 20kW of usable active power<\/strong>.<\/p>\n

The system uses a 3-phase input \/ single-phase output architecture<\/strong>, making it suitable for facilities with three-phase utility supplies and critical single-phase loads.<\/p>\n

The included PL31-BR20120FL battery box<\/strong> contains 20 \u00d7 12V 9Ah maintenance-free VRLA batteries<\/strong>, providing approximately 2.16kWh of nominal stored battery energy<\/strong>.<\/p>\n

The modular architecture allows the system to be expanded to up to four PL31 FL 10.0k HC power modules in parallel<\/strong>, providing a maximum scalable capacity of 40kVA \/ 40kW<\/strong>.<\/p>\n

Additional compatible battery boxes can also be added where longer backup duration is required.<\/p>\n
