20KW Rack Mount UPS 1A 2A 4A 6A Adjustable True Double Conversion Technology

Tafeng Technology was founded in 2001 in Shenzhen. We design and build critical power infrastructure — UPS systems, transformers, voltage stabilizers, battery systems, and data center equipment.

We've been doing this for 25 years. Our customers are in more than 65 countries, mostly in sectors where a power failure isn't an option: hospitals, factories, telecom networks, and data centers.

The product range has grown over time. What started as a focused power protection business now includes energy storage systems and intelligent data center infrastructure, but the core work hasn't changed — keeping equipment running when the grid can't be trusted.

UPS Systems — Offline, Line Interactive, Online, High Frequency, Low Frequency, and Modular models. They're used in server rooms, hospitals, telecom equipment, and industrial control systems.

Transformers and Voltage Regulation — Isolation transformers, dry-type transformers, and automatic voltage stabilizers. These fix unstable grid voltage and isolate sensitive equipment from electrical noise.

Energy Storage — Systems for homes and for commercial/industrial use. Customers deploy them for peak shaving, backup power, and tying renewable energy into their operations.

Data Center Infrastructure — Modular data centers, precision air conditioners, and environmental monitoring systems.

Batteries — VRLA and lithium systems for UPS backup, energy storage, and telecom.

We have 25 engineers. They work on UPS topology, battery integration, transformer design, and power quality monitoring. The team tends to prioritize problems they see in the field — if a product design breaks down in a real installation, that's where the next round of R&D starts.

Our factory in Shenzhen covers about 6,000 square meters. Monthly output looks like this:

Quality control runs from incoming material inspection through to final testing. It's not fancy, but it's consistent.

• Medical — CT scanners, MRI, DR, mammography.
• Data centers and telecom — Server rooms, edge data centers, telecom networks.
• Industrial — Manufacturing plants, oil & gas, mining, automation.
• Public infrastructure — Airports, rail transit, government buildings, schools, hospitals.

We support customers in 65+ countries. The typical engagement covers product selection, system design, installation guidance, remote support, and after-sales service. Regional power conditions vary a lot — what works in Shenzhen doesn't always work in Lagos — so most projects start with understanding the local grid.
