Diligateups’ high-tech modular UPS

一、Challenges and Trends of Traditional Data Centers

High Costs

2. Hard to scale up

As business demands have increased, the load factor has gradually risen, and space and equipment capacity have become limited.

New UPS systems are difficult to integrate with existing systems and environments; after deployment, system operating status is hard to monitor.

Compatibility between old and new power distribution systems raises new technical challenges, and it is difficult to expand UPS capacity without disrupting the stable power supply to critical loads.

Input/output cabling requires capacity upgrades or modifications to the original wiring structure, making construction difficult.

3.Traditional power distribution equipment is difficult to install and maintain

Difficulties with transportation, installation, and construction

Capacity expansion requires re-transporting and reinstalling complete distribution equipment

Bulky size with complex wiring

Heavy daily maintenance workload on O&M staff

Component failure requires power-off replacement — time-consuming

Non-specialists cannot perform maintenance, and troubleshooting is difficult.

Reduced risk of power outage

Seamless switchover upon any single-point failure

Centralized control and centralized bypass
If one path fails, the other takes over — eliminating single points of failure and improving system reliability by 30%

Leading cooling technology

With one fan failure, the system still carries 50% load; with two fan failures, it carries 30% load
Forced turbulence technology improves heat dissipation by 10%
Refined fan matching delivers an energy efficiency ratio 50% ahead of competitors

Based on a mature thermal design platform with optimized cooling and high-margin components, the UPS delivers full-load, non-derated operation at ambient temperatures from 0 to 40°C, significantly improving system reliability.

High-altitude design — no derating at altitudes up to 1,500 m

Using a dip-coating process with triple-protection varnish, this solution is suitable for harsh operating environments such as salt spray, dust, and high temperatures and humidity.

Green and energy-efficient design

Low Harmonics: Low-harmonic and soft-start technologies reduce the cost of diesel generator investments.

High Power Factor: The output power factor (PF) can reach 1, allowing for an 11% higher load capacity than traditional UPS systems. This effectively reduces grid pollution and avoids the dilemma faced by traditional UPS systems, where pollution occurs first and remediation follows
