The FSP240-A2AR3 is part of FSP Power Solution's Power Delivery (PD) 3.1 adapter portfolio, a 240 W AC to DC USB-C PD 3.1 desktop adapter with an IEC320-C14 Class I inlet. It supports output profiles from 5 V to 48 V, covering the full Extended Power Range (EPR) for next-generation PD-compatible devices. Operating from 90 to 264 Vac, this PD adapter delivers reliable power for high-performance equipment. Certified to IEC/EN 62368-1 safety, EN 55032/CISPR 32/FCC Class B EMC, and CoC Tier 2 / DOE Level VI efficiency, it is designed for next-generation commercial and industrial applications.

What advantages does the FSP240-A2AR3 provide with PD 3.1?

Compared to PD 2.0 and 3.0, the new USB-C PD 3.1 standard extends the power range from 100 W to 240 W, with higher voltage options at 28 V, 36 V, and 48 V. With Adjustable Voltage Supply (AVS), the PD 3.1 enables an intelligent power negotiation. The precise voltage adjustments function with stable voltage outputs (15V to 48V) in 100mV increments. This ensures optimal performance and enhances device stability for critical applications. With EPR and AVS, a USB PD3.1 Adapter like the FSP240-A2AR3 can power high-performance laptops and monitors, and even e-bikes, power tools, or industrial systems — all with a single standardized connector.

USB Power Delivery Standards Overview

With adjustable voltage and dynamic power management USB PD 3.1 enables a power delivery tailored to modern applications. FSP Power Solution PD adapters comply with the latest USB-C PD 3.1 standard. With the FSP240-A2AR3, our PD 3.1 line-up supports up to 240 W for next-generation applications and ensures compliance with global safety and efficiency requirements.

FSP240-A2AR3 with USB 3.1: Data transfer and fast charging over a single cable

As part of the FSP's PD adapter series, the FSP240-A2AR3 features USB 3.1 Type-C Power Delivery. USB 3.1 was the USB standard that first natively integrated the USB Type-C connector and USB PD capabilities, allowing for both high-speed data transfer (up to 10Gbps) and increased power delivery (up to 100W) over a single cable.

FSP provides a comprehensive selection of USB 3.1 PD adapters. With FSP240-A2AR3 as the highest-capacity PD adapter in the series, the power options range from 45W to 240W. Our product lineup includes both compact wall-mount adapters and desktop power supplies. Additionally, the interchangeable plug-in model provides flexible usage.

Benefits of the FSP240-A2AR3 with USB-C PD 3.1 in real-world applications

The USB PD 3.1 specification supports a maximum output of 240W and allows devices to intelligently negotiate the optimal power level. For example, the 240W FSP240-A2AR3 PD adapter can deliver full power to an e-bike system, while remaining backward compatible with e-tools and USB-C monitors. Similarly, the 180W FSP180-A1BR3 is suited for e-tools and displays, while the 140W FSP140-A1AR3 is optimized for monitors and TVs.

This dynamic power negotiation ensures that each device only draws the power it is designed to handle. Built-in protection features such as OCP, OVP, and OTP further prevent overcharging or overheating, making PD 3.1 adapters safe for both consumer and industrial use.

Case Sharing: How E-Bike Battery Makers Accelerate with FSP's Complete PD 3.1 Solution
