Frequently Asked Questions
What is the difference between double-conversion and line-interactive UPS systems?
Double-conversion (online) UPS systems, like the OL1K5RM, continuously convert AC to DC and then back to AC, providing a constant, clean power supply with zero transfer time. Line-interactive systems only engage the inverter during power fluctuations, offering less protection for highly sensitive equipment.
Can the runtime of the CyberPower OL1K5RM be extended?
Yes, the OL1K5RM supports Extended Battery Modules (EBMs), allowing organizations to significantly increase the backup runtime for connected equipment during prolonged power outages.
What type of equipment is best suited for this 1.5 kVA UPS?
This 1.5 kVA / 1200 W UPS is ideal for protecting critical single servers, network switches, routers, firewalls, and small storage arrays in server rooms or network closets.
Does this UPS provide pure sine wave output?
Yes, the CyberPower OL1K5RM provides pure sine wave output, which is essential for active PFC power supplies and sensitive electronic equipment to prevent unexpected shutdowns or damage.
