The POWER+ SA 20/30/40KVA is one of the most sophisticated Stand-alone ON-LINE double-conversion UPS  - Uninterruptible Power Supply -  on the market today.

In general, an Uninterruptible Power Supply (UPS  - Uninterruptible Power Supply) provides backup power for use when the utility ac electric power mains fail or drop to an unacceptable voltage level. POWER+ SA  20/30/40KVA is a whole lot more.

POWER+ SA 20/30/40KVA is designed to protect your data and equipment and minimize downtime and other adverse effects normally incurred by power irregularities and failures

POWER+ SA 20/30/40KVA continually eliminates surges, spikes and sags that are inherent in commercial utility power. Over time, these irregularities shorten the life of equipment and components. The efficiency of POWER+ SA 20/30/40KVA thus helps to extend the life of your equipment, even through normal use when the input power system is constant and continuous.

POWER+ SA 20/30/40KVA requires very little attention or intervention during normal operation; however, you should read and understand the procedures described in this manual to ensure trouble-free operation.

POWER+ SA 20/30/40KVA is a parallel redundant UPS  - Uninterruptible Power Supply - in the event of a failure of one power board, the UPS  - Uninterruptible Power Supply - continues to operate and the remaining power boards compensate for the missing board (within limits).

The POWER+ SA 20/30/40KVA is available in two versions: a 20 kVA model 30 kVA model and a 40 kVA model.

• POWER+ SA is reliable thanks to its parallel redundant topology.
• POWER+ SA is a true on-line battery design according to IEC62040-3.
• POWER+ SA is a "green" power solution thanks to THD of 5% at the input,
  and provides "clean" power to your loads.
• POWER+ SA employs active current sharing at the input / output.
• POWER+ SA has an overall efficiency of up to 96% and backup efficiency of 98%.
• POWER+ SA is light and small, weighing 68 kg (approximately) and with a footprint of less than .28 m².
