480V / 277V Modular UPS

480V / 277V (20KVA – 200KVA) 3 Phase Modular UPS

  • Customizable power capacity sizes to support your equipment load(s).
  • N to N+X to 2N or greater redundancy options so you are never caught off guard if a system failure, resulting in downtime, ever occurs.
  • Smaller footprint, different form factors, and higher rack densities to increase rack and floor space, and provide you with more power.
  • Increased VRLA battery life to lower your costs.

Contains rechargeable ZincFive nickle-zinc (NiZn) batteries that offer a more reliable, more powerful, greener, and safer alternative to traditional lead-acid and lithium-ion batteries. The high energy density also creates batteries half the weight of traditional batteries, that are both non-flammable and easily recyclable, with extended cycle and shelf lives, that retain thermal stability while maintaining fast recharge.
