In mission-critical environments — from data centers and industrial plants to healthcare facilities and telecom networks — a UPS is far more than a backup. It’s the last line of defense against costly downtime.

It must be proven before the system ever reaches the site. That’s why Factory Acceptance Testing (FAT) plays a vital role in every EverExceed UPS.

Why FAT Matters for UPS Systems

Installing a UPS is a major investment, and failures on-site are expensive — in repair costs, operational disruption, and downtime.

FAT ensures that the UPS:

· Performs exactly as specified

· Activates all protection mechanisms correctly

· Communicates reliably with monitoring systems

· Maintains stable operation under real-world conditions

By shifting risk detection to the factory, FAT gives customers confidence that their UPS will perform when it matters most — and when they return to the site after delivery, they see firsthand the value of our partnership and the reliability we promised.

FAT Aligned with International Standards

EverExceed’s FAT follows IEC 62040 standards, covering:

· IEC 62040-1 — Safety Requirements

· IEC 62040-2 — EMC Requirements

· IEC 62040-3 — Performance & Test Methods

Voltage regulation, transfer performance, overload capability, and operational stability are all verified according to internationally recognized methods. Compliance isn’t just a certification — it’s built into the testing process.

How EverExceed Executes FAT

Relying on EverExceed’s integrated R&D, manufacturing, and testing capabilities, every UPS module undergoes system-level FAT under real operating conditions, ensuring that reliability is “seen and proven” before shipment.

The FAT process includes three key stages:

1. Visual Inspection & Assembly Verification — checking mechanical integrity and proper assembly

2. Electrical Safety Verification — validating insulation, grounding, and protection functions

3. UPS Functional & Performance Testing — confirming startup, load operation, battery mode, and communications

In a recent project with TCR Company, we ran continuous operation testing during FAT, demonstrating stable performance and full readiness for deployment.

100% Tested, Fully Traceable

Every UPS unit is tested before shipment, with complete, traceable records. For project-based orders, Witness FAT is available for full transparency.

At EverExceed, FAT reflects our commitment to quality. From design and component selection to system-level validation, every UPS leaving the factory represents dependable, reliable power solutions that customers can trust worldwide.
