OmniOn Power’s new 30 kW rectifiers for EV charging stations

OmniOn Power has developed new 30-kilowatt power supplies specifically designed for the EV market. The EV100H3NK and EV101H3N1K rectifiers convert commercial AC power to DC power for EV fast charging stations.

To improve charger reliability and availability, the rectifiers can be deployed in parallel configurations of up to 12 or more power supplies, providing total system capacities up to 360 kW and higher. The rectifier modules feature plug-and-play connectivity, allowing units to be quickly swapped out when servicing to minimize downtime. They also integrate CAN automotive communications protocols, streamlining integration and communication between components.

“While this may be our first product specifically designed for EV charging, we have an extensive history of working with customers to design and develop innovative power solutions for their critical infrastructure, such as the latest wireless architectures and high-performance data centers,” said Gopal Mitra, Industrial Segment Leader for OmniOn Power. “This inaugural entry into the EV market allows us to [offer] our deep domain expertise to customers looking to build their next DC fast charger.”

The EV100H3NK and EV101H3N1K rectifiers feature a 480 V three-phase input, 30 kW DC output, and an adjustable output range of 50-1,000 volts DC that is settable by the host charger. Each measures 13.23×3.3×17.25 inches, and supports 19-inch rack mounting. Remote firmware downloads support field upgrades. The rectifiers meet UL, VDE and CE safety requirements.

The EV101H3N1K adds a discrete emergency power-off circuit for added safety. This functionality enables the rectifier to comply with local or regional jurisdictions that require an electromechanical energy disconnect for rapid shut-down in case of emergency.

“Consumers want to know that a fast charger is going to be available and fast when they drive up to it. Using highly reliable, high-capacity power supplies as the building blocks for next-generation EV chargers will help to address these issues,” Mitra continued. “Our history of maintaining and servicing DC fast chargers as well as similar critical DC equipment helps us to anticipate power challenges the industry may face and engineer solutions that help improve uptime and performance.”
