Power+ SA 10 KVA to 80 KVA Online UPS

The Power+ SA 20/30/40KVA is one of the most sophisticated Stand-alone ON-LINE double-conversion UPS on the market today. In general, an Uninterruptible Power Supply (UPS) 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 - in the event of a failure of one power board, the UPS 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.

Features

  • POWER+ SA is reliable thanks to its parallel redundant topology.
  • True on-line battery design according to IEC62040-3.
  • "Green" power solution thanks to THD of 5% at the input, and provides "clean" power to your loads.
  • Employs active current sharing at the input / output.
  • Overall efficiency of up to 96% and backup efficiency of 98%.
  • Units are light weight and small in footprints.
