CyberPower OLS3000E is a high-performance UPS featuring online double-conversion topology, which provides seamless pure sine wave power for mission-critical devices such as NAS and servers, DVRs/surveillance systems, transportation and infrastructure, and emergency systems. It’s typically integrated in the back office, server room, and data center environment. By manually setting the UPS to ECO Mode, the UPS automatically detects the input power quality and discerns whether it should operate in Line Mode or ECO Mode. Under poor power conditions, the UPS will run in Line Mode, which guarantees the highest level of protection and the best possible power quality. When the input power quality is acceptable, the UPS switches to ECO Mode, which increases the total output power efficiency by up to 96%. The product is equipped with a Maintenance Bypass Switch. By flipping the switch, the power supply is safely transferred to utility. This allows service personnel to carry out fast on-site maintenance without having to shut down any connected equipment.

Why Buy from Tech Trade Group?

🚚 Free Shipping

We offer free shipping Australia-wide* on most products, making it easier and more affordable to shop with us. Standard orders are shipped via Australia Post.

Please note:

  • A delivery fee may apply for heavy, oversized, or bulky items.
  • Orders to remote or regional areas may take longer to arrive.
  • Where additional charges apply, these will be clearly shown at checkout.

✅ Quality Assurance (TTG-T1 Certified Products)

Every refurbished unit we sell undergoes thorough testing and professional cleaning to ensure it meets Tech Trade Group Tier 1 Refurbished Products Certification. Devices may show minor cosmetic imperfections like light scratches or surface marks, but each one is guaranteed to perform like new.

🖥️ Commercial-Grade Quality

Our refurbished units come from the robust, commercial-grade lines of top-tier manufacturers such as Dell, HP, Lenovo, and Samsung to name a few. Originally designed for enterprise use, these models feature superior build quality and commanded premium prices when new. Most of our stock comes from large corporations and government departments, where equipment is typically well-maintained. As a result, these commercial-grade machines often outlast typical consumer-grade alternatives.

🛡️ 12-Month Warranty

We stand behind the reliability of our refurbished products. That’s why every unit (unless otherwise specified) comes with a full 12-Month Warranty, covering any hardware faults that may arise during this period. We also offer an extended 24-Month Warranty for just $99.

💰 Save Your Money!

Why pay full price for new equipment when you can get the same performance for a fraction of the cost? With savings of up to 80% on Laptops, Desktops, Monitors, and even Apple devices, buying refurbished just makes sense. Especially considering that there have been minimal breakthroughs in computer technology over the last 3–5 years — there’s never been a better time to make the switch.
