FCL Components Releases the FTR-L1 a Latching Relay Series for AI Servers (EMEA)
Hoofddorp, The Netherlands – September 15, 2026 –CL Components Europe B.V., has released FTR-L1 and FTR-L1R, a small-body, high-current relay series designed for AI server Power Supply Units (PSU’s) with a built-in Automatic Transfer Switch (ATS).
The FTR-L1 (25A, 277VAC) and the FTR-L1R (40A, 277VAC) are 2-coil latching relays, so there is no need to waste power on coil consumption. A 1a+1b contact configuration makes the series suitable for switching AC power sources, and the relays offer a high dielectric strength of 2,500VAC between open contacts.
The FTR-L1 series features a wide 4.5mm contact gap, making it capable of supporting operation in environments at altitudes up to 5000m. The series is in compliance with product safety standard IEC 62368-1:2023.
The Role of Relays in AI Systems
In AI systems, the PSU plays a critical role in delivering stable and sufficient power to high-performance components like Graphics Processing Units (GPUs) and AI accelerators. These components require much more power than in regular computers, so AI servers often use high-wattage, redundant PSUs to ensure reliability and avoid downtime.
In PSU’s, the FTR-L1 relay series’ role is to switch to an AC power source in an emergency as an ATS functionality, an essential feature for customers requiring high availability and continuous performance.
The series features a slim, low-profile design measuring just 50 × 20 × 27mm, making it ideal for the compact, space-efficient PSU enclosures specified by Open Rack V3 (ORv3). The FTR-L1 is designed to meet the AC input current requirements of 3 kW-class ORv3 PSUs, while the FTR-L1R supports the higher power demands of 5.5 kW-class ORv3 High Power Rack (HPR) PSUs.
The FTR-L1 series has already generated strong interest among power supply manufacturers, and orders for mass-production units are now being accepted. Looking ahead, FCL Components is developing higher-capacity models to support next-generation ORv3 HPR2 PSUs, further expanding the series' capabilities for high-power data center applications.
