Wandtung

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. 1

    ATS/STS automatically switches between primary and backup power feeds.

  2. 2

    Modular UPS conditions and protects power with built-in redundancy.

  3. 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

FAQ

Frequently Asked Questions

What is the difference between an ATS and an STS?

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.
