Description

The APS-RTx PowerLine Flex PL31-20K-P2-B3-KIT is a scalable 20kVA / 20kW online UPS system comprising 2 parallel PL31 FL 10.0k HC power modules and 3 PL31-BR20120FL external battery boxes.

The two 10kVA / 10kW power modules operate in parallel, providing a combined system capacity of 20kVA / 20kW while maintaining flexibility for further capacity expansion.

Using online double-conversion technology, connected equipment is continuously supplied through the UPS inverter, providing stable, conditioned power with zero transfer time during utility failure.

Each power module delivers a 1.0 output power factor, allowing the complete system to provide up to 20kW of usable active power.

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

Each included PL31-BR20120FL battery box contains 20 × 12V 9Ah maintenance-free VRLA batteries and provides approximately 2.16kWh of nominal stored battery energy. With three battery boxes, the complete system provides 6.48kWh nominal battery capacity.

The modular architecture supports up to 4 PL31 FL 10.0k HC power modules in parallel, allowing the system to expand to a maximum capacity of 40kVA / 40kW.

This configuration provides the highest battery capacity of the PL31-20K configurations, making it suitable where longer backup duration is required.

System Technical Specifications

Included Battery System

Battery Capacity

Each included battery box provides:

20 × 12V × 9Ah = 2.16kWh nominal battery capacity

With three battery boxes:

3 × 2.16kWh = 6.48kWh nominal battery capacity

Actual backup time depends on:

• Connected system load
• Battery age and condition
• Ambient temperature
• Battery discharge rate
• UPS operating efficiency

Compared with the PL31-20K-P2-B2-KIT, this configuration increases nominal battery capacity from 4.32kWh to 6.48kWh while retaining the same 20kVA / 20kW output capacity.
