Where TwinSource switches work

Anywhere a single-corded load has to stay up and two sources of power are available. Pick an application to see where the switch sits, what it protects and which families fit.

AI Data Centers

Static transfer switches for AI data centers: busway-fed above the racks, rack-mount in network racks, wall-mount at CDUs and controls.

TPU/GPU Clusters

A TPU/GPU cluster is only as available as its least-protected switch, controller or pump. See where a rack-mount static transfer switch closes the gap.

SECONDARY LOOPFACILITY WATERABLIQUID-COOLED RACKSCDUSTS

Cooling Distribution Units (CDUs)

When a CDU loses power, liquid-cooled racks have seconds of thermal margin. A TwinSource STS keeps pumps and controls on a healthy source.

ABSINGLE-CORDED LOADS + STSCRAH

Traditional Data Centers

Give single-corded servers, network and storage equipment both sides of a 2N power system with a rack-mount static transfer switch from TwinSource.

ABCHILLERCONTROLSPUMPSCOOLING TOWERSTS

HVAC / Chiller Controls

A power blink can put a chiller plant into a restart cycle that lasts minutes. Keep chiller controls, PLCs and drives on two sources with a TwinSource STS.

Communications & Controls

Keep routers, radios, dispatch consoles and control networks on two AC sources with a rack-mount TwinSource static transfer switch.

UPSGENFACILITYSECURITY + BMS CONTROL ROOMSTS

BMS / Surveillance Controls

Keep building management servers, access control and video recording on two power sources so the facility never goes blind during an electrical event.

SCADA / Utility Controls

Keep SCADA servers, RTUs, HMIs and plant control systems on two AC sources. TwinSource static transfer switches transfer as fast as a quarter cycle.

Semiconductor / Chip Fabrication

Voltage sags still stop fab tools that meet SEMI F47. A TwinSource STS moves tool and facility loads to a healthy source as fast as a quarter cycle.

Nuclear Power Applications

Protect non-safety plant computers, security, radiation monitoring and emergency response facilities with two sources and transfers as fast as ¼ cycle.

Air Traffic Control Applications

TwinSource static transfer switches keep controller displays, voice switching and radar processing on two sources, transferring as fast as a quarter cycle.

Renewable / Wind Farm / Utility Controls

Keep plant controllers, SCADA, met stations and grid telemetry powered at unmanned renewable sites with a TwinSource static transfer switch.
