What customers say
Customers highly value the CyberPower OL6KRT for its robust reliability and professional grade performance, especially its true sine wave output protecting sensitive IT gear. Its ability to handle substantial loads during outages is frequently praised. The hot swappable batteries offer excellent convenience for continuous operation environments. However, a key drawback noted by users is the significant operational noise from the cooling fans, making it unsuitable for quiet spaces. Installation planning is also necessary due to the unit's considerable weight and size. Overall, users find the exceptional quality and performance justify the investment for mission critical applications.
Know before you buy
Double-conversion topology means the UPS continuously converts incoming AC power to DC and then back to clean AC. This process isolates your sensitive electronics from power surges, spikes, and noise, providing a constant, stable power stream with zero transfer time during an outage.
Yes, the OL6KRT is designed for flexibility and includes the necessary hardware for both rack-mount and tower installations. Its 6U form factor is standard for enterprise-grade rack enclosures.
The unit comes with a pre-installed RMCARD205 network card, which allows you to monitor and manage the UPS remotely via a web browser or network management software. Additionally, the LCD panel is removable and can be mounted up to ten feet away from the unit for easier local access.
Yes, this model supports the addition of up to ten Extended Battery Modules (EBMs). This allows you to scale your backup capacity significantly based on your specific runtime requirements.
ECO Mode allows the UPS to bypass the internal power conversion process when utility power is stable, achieving efficiency ratings of over 96%. This reduces energy consumption and heat output, helping to lower operational costs without sacrificing protection.
Yes, the system is designed to allow for maintenance or battery replacement without requiring you to power down your connected equipment. This ensures your critical infrastructure remains operational even during routine service.
