OmniOn unveils compact 2.8kW supplies for AI & IoT

OmniOn Power has released a new series of high-power density power supplies designed to meet the increasing electricity demands driven by artificial intelligence (AI) and Internet of Things (IoT) applications.

The newly introduced HPR-series encompasses the HPR2912TEX12 AC/DC rectifier and HPR2812DCX12 DC/DC converter, both capable of delivering up to 2.8kW of power. These units are intended for 12V distributed architecture systems and target a diverse range of networking and data centre applications, such as optical line terminals, aggregation routers, cloud computing infrastructure, and disaggregated memory banks.

According to OmniOn Power, the devices have a mean time between failures greater than 1.5 million hours at 40°C, a metric that the company says demonstrates the reliability expected by operators of modern server and storage equipment.

Vito Savino, Data Centre and Wireline Segment Leader for OmniOn Power, outlined the context for the release. "Today's optical networking and data center applications require more power than ever before to support innovative artificial intelligence and Internet of Things (IoT) applications," he said. "This increase in computing demand has put an even larger emphasis on power density and efficiency in these applications. Our new HPR-series power supplies provide the high power output required in compact footprints and with high reliability, efficiencies, and power densities."

The HPR2812TEX12 rectifier features an input range of 90-264 volts AC and delivers a 12.3 VDC output at an efficiency above 96% - measured to the 80 PLUS Titanium standard - with a power density of up to 69W per cubic inch. Meanwhile, the HPR2812DCX12 DC/DC converter accepts a 36-72 VDC input, supplying 2.8kW of power at a 12.3V output. The company reports it sustains full output without derating at input voltages above 40V and at temperatures up to 45°C. The converter is designed as a drop-in mate for the rectifier in terms of output, size, and connectors, facilitating integration and system upgrades.

Both models are manufactured in a compact enclosure measuring 1.57 inches in height, 7.68 inches in depth, and 3.39 inches in width. This size makes their 2.8kW output among the highest in similar form factors currently available, according to the company. This enables equipment manufacturers and operators to design systems with greater power without needing to parallel multiple, lower-output power supplies. It also provides a streamlined pathway for upgrading AC-input and DC-input systems in response to higher processing requirements or expanded feature sets.

Cooling is managed through a back-to-front airflow architecture, while integrated safeguards such as overvoltage and overcurrent protection aim to ensure safe operation. Additional features include a PMBus digital communication interface, supporting remote control, configuration, and monitoring of the power supplies within deployed systems.

OmniOn Power states the HPR-series is suitable for a broad array of networking and data centre environments employing 12V distributed architectures, such as optical line terminals, cloud computing, computer-aided design clusters, disaggregated memory infrastructure, aggregation routers, and switches.

The announcement comes against the backdrop of increasing network traffic and system complexity, as AI and IoT technologies place new strains on data centre energy architecture. The company says its approach is designed to address evolving customer needs for both power and operational flexibility within space-constrained deployments.
