TRENDING constraint. Today, the focus is on outlet-level protection regarding power consumption.
With power supplies reaching highs of 6.6kW, current draw has increased significantly. Additionally, traditional breakers are typically capped at 16 amps, so any power drawn over 16 amps will trip the breaker. If you put two 10- amp outlets on a breaker, it will keep tripping. The solution is to provide dedicated protection at each outlet, each with its own breaker or fuse. It’ s recommended to have 10kAIC or over as the standard interrupt rating. This way, whenever a trip occurs, it immediately alerts the end user.
High density is not just about the number of outlets on the PDU; it’ s also about the number of breakers. For example, if someone is deploying eight servers, each with six outlets, that’ s 48 breakers to monitor. That is why having advanced metrics, such as circuit breaker trip forensics and trip current measurement, have become essential so that all your outages are captured when they occur or even before.
How do the Raritan PX4 intelligent PDUs specifically address the need for load balancing in complex GPU cluster deployments?
All our Raritan PX4 rack PDU products include both standard and advanced power metering capabilities. But when it comes to load balancing, it’ s plug-and-play. We offer a power calculator on our website. Customers enter the load of each server power supply deployed in that rack, and the tool provides a visual guide for how an operator should go about plugging into those units and how to maintain balance across the rack.
From an intelligence perspective, we offer per-outlet monitoring – not just voltage and amperage, but comprehensive metrics at both the outlet and inlet levels. This ensures balanced loads and improved overall rack efficiency.
How does Raritan address the challenge of outlet type by adapting the PDU for new, higher-density, and temperature connectors while maintaining serviceability?
We offer standard and custom PDUs to support C22 and Anderson Saf-D-Grid connector requirements.
The C22 socket is rated to operate at 155 ° C. However, real-world data centre environments rarely exceed 40 ° C. The challenge is that vendors require a specialised cable capable of handling 155 ° C, but currently, such cables are not widely available.
To address this, we are developing a CX4 outlet that supports C13, C15, C19, and C21 connections on the PDU. This singleoutlet design accommodates multiple outlet combinations, providing greater flexibility and simplifying deployment. Our PDUs remain 60 ° C rated for operation, in line with our standard specification, and are fully compatible with all IT equipment.
Anderson’ s connectors are a specialised outlet connector designed to support higher amperage applications. C22 outlets are capped at 16 amps per outlet, but Anderson outlets offer both 20- and 30-amp connectors. Raritan offers PDUs supporting both the 20-amp and 30-amp Saf-D-Grids, including 30-amp breakers, which are offered across the board.
Additionally, Anderson connectors are designed to operate at 480 / 277 volts instead of the traditional 400 – 415 volts.
Therefore, many equipment vendors and hyperscalers are moving toward this because it increases rack capacity and power supply.
The benefit is that you can use two 30-amp connectors to serve the same purpose as four connectors from an IEC outlet, delivering significant gains for hyperscalers.
