Critical Power Solution
Redundant, monitored power architecture from utility feed to IT load.
The Problem
Customer Challenge
Mission-critical facilities cannot tolerate power interruption, requiring redundancy and monitoring at every stage from utility/generator input through UPS, distribution and the rack itself.
The Approach
Solution Architecture
Wandtung designs redundant power architectures combining ATS/STS transfer switching, modular UPS, and intelligent PDUs, monitored end-to-end so operators can see and respond to issues before they affect load.
System
System Components
ATS / STS
Automatic and static transfer switching between power sources.
Modular UPS
N+X redundant power protection.
Intelligent PDU
Outlet-level monitoring and remote switching at the rack.
Architecture
How It Works
- 1
ATS/STS automatically switches between primary and backup power feeds.
- 2
Modular UPS conditions and protects power with built-in redundancy.
- 3
Intelligent PDUs distribute and monitor power down to the outlet level.
Configuration
Product Configuration
ATS PDU
Rack PDU with a built-in automatic transfer switch for dual-feed redundancy.
STS (Static Transfer Switch)
1U rack-mount static transfer switch, dual-source redundancy with <10ms seamless transfer.
Modular UPS
Hot-swappable power module UPS for scalable, high-availability critical power.
Intelligent PDU
Network-managed rack power distribution with monitoring, metering and remote switching.
Advantages
Technical Advantages
- Redundancy designed at every stage, not just the UPS
- End-to-end power visibility
- Modular scalability as load grows
Process

FAQ
Frequently Asked Questions
An ATS (automatic transfer switch) mechanically switches load between two power sources, typically with a brief transfer time, while an STS (static transfer switch) uses solid-state switching for near-instantaneous transfer, used where even momentary interruption is unacceptable.
