53043 Qoltec 3000VA Online (Double-Conversion) UPS/USV

High-Availability Tower Online Double-Conversion UPS for single-phase IT protection with the 53043

The 53043 is a 3000VA/2400W single-phase online UPS engineered to isolate sensitive IT loads from upstream disturbances while maintaining continuous power delivery to rack-adjacent edge infrastructure. By using double-conversion topology, the 53043 continuously regenerates a clean sinewave output, improving compatibility with modern server and storage PSUs and reducing risk from voltage sags, transients, and frequency variation.

Designed for enterprise wiring practices, the 53043 accepts a hardwire input feed to support controlled installation and predictable upstream protection coordination. Downstream distribution is optimized for mixed IT and peripheral connectivity through 2x IEC 60320 C13 plus Schuko (Type F) and CEE 7/5 (Type E) outlets, enabling structured power segmentation for servers, network appliances, and management equipment. The 53043 aligns with continuity-focused deployments where stable output quality and deterministic switchover behavior are required for single-phase environments.

Why Choose the 53043?

The 53043 delivers a practical density-to-runtime profile for edge racks and small server rooms, combining online conditioning with enterprise-grade continuity in a tower footprint. For IT teams standardizing single-phase UPS protection, the 53043 supports scalable rollout logic by providing consistent output characteristics, predictable load handling, and clean power for mixed hardware generations without relying on line-interactive correction stages.

Qoltec designs power protection platforms with an emphasis on operational reliability, electrical safety, and integration into modern data centre standards. The engineering approach prioritizes stable conversion, robust connectivity, and deployment flexibility suitable for infrastructure operators managing diverse PSU behaviors and availability requirements.

Key Applications:

• Edge rack power continuity
• Server and storage runtime protection
• Network and security appliances
• Remote office/branch IT rooms
• Power conditioning for sensitive loads
