The BMXCPS3500 is a 36 W AC power supply module for the Schneider Electric Modicon X80 platform. It delivers stable backplane power for PAC systems such as the Modicon M580 and Modicon M340.
With a 100–240 V AC universal input, it supports global power standards and is suited for high-demand racks containing CPUs, communication modules, and high-density analog I/O. Built-in protection (overload, short circuit, overvoltage) ensures reliable operation, and certain redundant architectures support hot-swap replacement to reduce downtime.

Q1: Difference between BMXCPS3500 and BMXCPS2000?
The BMXCPS3500 provides 36 W, compared to 20 W for the BMXCPS2000. It is recommended for racks with higher power consumption to avoid backplane voltage drops.
Q2: Does it power field devices?
No. It powers the rack backplane only. Field devices require a separate 24 V DC supply (e.g., Schneider Phaseo ABL8 series) to isolate field noise from controller logic.
