STANDARDS
Listed to UL 1778 UPS standards, and CSA certified. Meets current requirements for safe high performance UPS operation.
for increased capacity and redundancy. |
• Achieves higher availability by reducing the |
number of UPS units required to power your |
data center. |
• Reduces total cost of ownership through the use |
of longer life batteries and simplified preventive |
maintenance. |
