APC Galaxy 3L 300kVA 300kW 400V 3-Phase UPS (G3LUPS300KHTS) | Scalable Power Protection for Critical Infrastructure

The APC Galaxy 3L 300kVA (G3LUPS300KHTS) is a high-density, 3-phase uninterruptible power supply (UPS) designed to simplify power protection for medium to large-scale facilities. Delivering a full 300kW of real power (PF=1.0), it ensures that your critical IT, commercial, or industrial loads are fully supported without power derating. This model is a “Without Internal Battery” configuration, specifically engineered for connection to external battery cabinets. This setup provides maximum flexibility for businesses to scale their backup runtime according to project-specific requirements while benefiting from Schneider Electric’s industry-leading efficiency and compact design.

Key Functions and Features

Unity Power Factor (PF=1.0): Provides exactly 300kW of active power, matching modern high-density loads and allowing for a more efficient use of electrical infrastructure.

High Operational Efficiency: Achieves up to 96% efficiency in online double-conversion mode and up to 99% in ECO mode, helping facilities drastically reduce total energy expenditure and cooling costs.

Compact Design with High Power Density: Optimized internal architecture provides a massive power output within a small footprint, saving valuable floor space in electrical rooms.

Simplified Installation & Commissioning: Includes pre-installed input, output, and bypass breakers. The front-access design allows for quick installation and ensures safe, easy maintenance.

Robust & Fault-Tolerant: Built for challenging environments, featuring a wide input voltage window and strong overload tolerance (150% for 1 minute).

Scalable Parallel Configuration: Supports paralleling up to 5 units to achieve either increased capacity (up to 1500kVA) or N+1 redundancy for mission-critical reliability.

Remote Management Ready: Fully compatible with the EcoStruxure™ IT suite for 24/7 cloud-based monitoring and smartphone-based management.

Frequently Asked Questions (FAQ)

Q1: What is the benefit of the G3LUPS300KHTS “Without Battery” model?

A: This model is designed for facilities that require high flexibility in backup time. By using external battery cabinets, you can configure precisely the runtime you need, whether it’s 10 minutes or several hours, using either VRLA or Lithium-ion technology.

Q2: How does the Unity Power Factor (PF=1) save costs?

A: PF=1 means 300kVA equals 300kW. Many older UPS systems have a 0.8 or 0.9 PF, meaning a 300kVA UPS would only provide 240kW or 270kW. With the Galaxy 3L, you get more usable power from the same footprint, often allowing for a smaller UPS to support the same load.

Q3: Can I use Lithium-ion batteries with this UPS?

A: Yes, the Galaxy 3L series is fully compatible with Schneider Electric’s Lithium-ion battery cabinets, which offer longer service life, less weight, and a smaller footprint compared to traditional VRLA batteries.

Q4: Is the installation process complicated?

A: No, the Galaxy 3L is known for its “simplified” design. It includes built-in breakers and a front-access design, which significantly reduces the time and cost associated with installation and commissioning.

Q5: How do I manage the UPS if I am off-site?

A: The unit is “EcoStruxure™ IT Ready.” By adding a network management card, you can monitor the UPS status, receive real-time alerts, and check battery health from any smartphone or web browser.
