Product description


The SANUPS A11J-S2 is a 10kVA Parallel Redundant double conversion online UPS.  Configured as a 10kVA Parallel UPS, the A11J-S2 offers expandability up to 20kVA of back up power.  In a 10kVA Redundant UPS configuration, the system provides enhanced (N+1) redundancy for application requiring the maximum in 7/24 up time.

Offering several industry-unique features, the SANUPS A11J-S2 10kVA Parallel Redundant UPS is ideal electrical power protection for many different types of commercial, industrial, medical, as well as military applications.


  • The SANUPS A11J-S2 utilizes the Double Conversion Online UPS topology
  • Under a 10kVA Parallel Online UPS configuration, the system offers maximum back up battery power capacity
    • This 10kVA Scalable UPS offers up to 20kVA of future expansion capabilities
  • When configured under a 10kVA Redundant UPS configuration, the system provides for maximum 7/24 up time offering (N+1) redundancy.
  • A 10kVA Modular UPS design utilizing a maintenance bypass circuit allowing for quick replacement of batteries, inverter, and transformer while the UPS system is on and still providing electrical power.
  • Wide Range AC power input capable
  • Power Correction and Pure Sine Waveform AC output to critical equipment
  • Long life, revision controlled Commercial Off-The-Shelf (COTS) product
  • Rugged enhancements such as protective chemical coatings, epoxy bonding of major components, and double sealed batteries

The advanced features and modular design of the SANUPS A11J-S2 make this 10kVA online UPS perfect in protecting critical equipment. Example deployments include manufacturing floors, small data centers, communications, as well as military C4ISR and C5ISR applications.


  • Rolling brownouts (surges and spikes)
  • Blackouts and power re-starts
  • Outdated or failed electrical wiring and or power distribution equipment
  • Severe weather events
  • Unstable power generation from local utilities or on-site generation

This 10kVA UPS utilizes the Double On-Line Power conversion topology.  By isolating critical equipment from the commercial power grid or onsite power generation sources the A11J-S2 10kVA online UPS internally conditions the incoming AC electrical power.  The resulting power output to target equipment is a pure sine wave in both frequency and voltage.   This clean, stable power will ensure the stable and efficient operation as well as protection of the sensitive and expensive critical electrical equipment.
