The need for safer, more agile, and uptime-driven solutions for power distribution systems is at an all-time high as data centers scale to meet growing demand for AI workloads, cloud computing, and other technological advancements.

In response to this growing market need, Starline has developed the Remote Power Actuator (RPA), an innovation designed to work with Starline's Track Busway system and help operators meet the challenges of high-density environments.

So, what does the RPA do, and how does it translate into operational advantages? We'll explore three practical ways RPA empowers data center operation teams to maintain safety, expand, and adapt without sacrificing uptime.

1. Enable Preventive Maintenance with Reduced Risk to Personnel

During routine maintenance, technicians need to remove or replace plug-in units connected to live busways.

In higher density data centers where equipment will likely be high-current, the risk of arc flash is greater, requiring the use of extensive PPE and safety approach guidelines to mitigate risks to crew entering the area with potential arc flash hazards, or the incident energy zone.

Increased Operational Safety
Starline’s Remote Power Actuator makes it possible for operators to engage or disengage plug-in units from a safe distance of up to ten meters, well outside the incident energy zone.

A fiber optic cable or Bluetooth connection is used to remotely engage the busway, allowing personnel to release the unit without physically touching it in energized areas.

Personnel are kept outside high-risk areas, ensuring compliance with local and international safety standards, fulfilling organizational environment, health and safety goals, and reducing the need to wear heavy protective equipment. Ultimately, this results in safer, more efficient maintenance operations without disrupting uptime or shutting down the busway.

2. Streamline Phased Deployments and Expansion Works

As client and facility needs evolve rapidly in recent years, data centers will need to incorporate a strategy called 'phased expansion' or retrofitting for expansion in stages into their operations. It is necessary to allow facilities to add new colocation tenants, increase rack power density, or deploy new IT equipment. The execution of each phase is usually accompanied by planned outages, manual installation, and complex coordination.

Rapid Deployment with Minimum Disruption

Aside from the flexibility of plug-in unit placement already available on Starline Open Channel Track Busways, the addition of the RPA means technicians are able to pre-install units at low-activity periods, then rotate and energize them remotely as needed. Torque sensors on the RPA ensure error-free operation and reduce the possibility of installation problems, one of the leading causes of data center outages caused by human error according to research organization Uptime Institute.

With this approach, colocation providers and enterprise operators can scale capacity just-in-time, allowing them to onboard your clients and workloads safely and quickly.

Furthermore, this minimizes disruption to adjacent systems and eliminates scheduling bottlenecks, enabling teams to speed up time-to-service.

3. Simplify Retrofits to Meet Evolving Power Demands

It is now increasingly important for data centers to upgrade power infrastructure at the rack level to support AI and high-performance computing workloads, which often generate higher power demands.

Real-time Installations in Live Environments

In high density environments, Starline's RPA allows facilities to execute safe, uninterrupted infrastructure changes of plug-in-units in T5 busway up to 1,250 amps ratings can be installed or replaced without powering the system down. By doing so, critical workloads are not required to be taken offline or relocated during the retrofit, minimizing downtime.

Data center operators can scale or reconfigure power capacity more efficiently and safely by deploying the RPA, adding more power feeds or swapping out existing feeds for higher amperages with minimal risk and operational disruption.

This operational agility enables facilities to easily support new AI-ready racks or reorganize power across their facilities via infrastructure changes when needed. This in turn ensures data centers are better placed to adapt to fast-changing power demands without compromising uptime or security.

Conclusion: Remote Actuation as a Safety and Uptime Imperative

As data centers become ever-on, ever-scaling, and always-on, operators need to prioritize safety, scalability, and uptime. The Remote Power Actuator from Starline addresses these requirements by providing a safer, smarter, and more flexible way to manage power distribution.

By mitigating arc flash risk during maintenance, enabling rapid expansions, and supporting live retrofits, the RPA's features complement expansion and retrofit operations, minimize disruptions to live operations, and address safety concerns, improving compliance standards for personnel safety in data centers.

Product Compatibility Note: At the time of writing, the Starline RPA is compatible with the E50 Series Enclosure plug-in units on the Starline T5 Track busway system.
