GRL’s 240W USB Power Delivery tester receives USB-IF approval for EPR product compliance testing

Cutting-edge USB-PD-C2-EPR tester is among the first on the market designed to validate USB Power Delivery up to 240W

Granite River Labs (GRL), a global leader in engineering services, test automation solutions for digital connectivity and charging technologies, and professional market access services, has announced that its comprehensive USB Power Delivery (USB PD) and USB Type-CⓇ test solution – the GRL-USB-PD-C2-EPR (C2-EPR) – has been approved by the USB Implementers Forum (USB-IF) to conduct compliance testing for EPR products.

The latest USB PD specification supports flexible power delivery up to 240 W over a single USB Type-C connector, making it suitable for a wide range of applications with power requirements above the previous limit of 100 W. However, it also presents developers with unique compliance, reliability and interoperability testing challenges.

The GRL C2-EPR provides compliance testing up to 240 W of power at the push of a button, and supports the USB PD 3.1 specification as both a Source and Sink for complete testing and validation. Other functions include fully automated functional safety testing required for IEC 62368-1 to validate Power Sourcing Equipment(PSE), Cables and Powered Devices that handle power higher than 100 W over digital ports for source devices and all consumer AV and IT equipment with USB Type-C ports. The solution is also fully backward compatible with the legacy USB PD Specifications.

Combining the GRL C2-EPR with the latest GRL A1-EPR Analyzer enables users to easily monitor protocol and power negotiation to understand the interoperability issues between various source and sink devices. This paints a broad picture of power delivery protocols between sources and sinks.

“As a cost-effective and user-friendly USB-PD tester, the C2-EPR fills a critical gap in the testing landscape. It is one of the first testers on the market capable of handling power up to 240W, making it indispensable for validating our series of USB power and charging port controllers,” said Veerappan Rajaram, Senior Director Application Engineering, Infineon Technologies. “With a rich array of features, it has been proven instrumental in significantly reducing costs, accelerating R&D efforts, and expediting time-to-market for our products, fostering enhanced confidence and efficiency.”

“The new GRL-C2 EPR is a great addition to the USB Power Delivery ecosystem and provides the industry with another reliable option for high wattage USB Power Delivery testing,” said Jeff Ravencraft, USB-IF President and COO. “We are pleased to have worked diligently with GRL to finalize this product’s readiness and confirm its full compliance with USB-IF specifications.”

“GRL is proud to cater to the ever-growing need to standardize charging ports and fast charging technologies by releasing this new, USB-IF approved USB PD compliance tester for EPR,” said Rajaraman Venkatachalam, GRL’s Executive Vice President of Protocol and Power Solutions. “Our expertise in USB Power Delivery provides fully-featured, integrated solutions and services that enable product developers to release reliable and
robust charging products efficiently and cost effectively.”
