BMXCPS3500 | Schneider Electric | Modicon X80 High-Capacity AC Power Supply Module

Product Overview

The Schneider Electric BMXCPS3500 provides high-capacity, regulated electrical power to standard Modicon X80 automation racks. Operating on a universal AC input, this primary power module converts mainline power into three isolated secondary direct-current (DC) outputs. It simultaneously drives high-density I/O configurations, advanced communication microprocessors, main CPUs, and external field instrumentation loops, serving as the foundational electrical core for heavy-duty process control and infrastructure installations.

Technical Specifications

Engineering Advantages

• Triple-Rail High-Output Architecture: High-density automation racks often cause standard power supplies to sag. The BMXCPS3500 resolves this capacity issue by outputting a boosted 4.5 A on the 3.3 V DC logic rail (15 W), 1.3 A on the 24 V DC system rail (31.2 W), and a dedicated 0.9 A on the 24 V DC sensor rail (21.6 W). This large power allocation runs extensive I/O architectures without requiring supplementary racks.

• Reinforced Dielectric Isolation Barriers: Cross-circuit electrical faults can permanently destroy processors. This module incorporates superior galvanic separation, withholding 1500 V between the primary stage and the backplane logic, and an elevated 2300 V between the primary lines and the 24 V DC sensor output. This barrier isolates field-level wiring anomalies and prevents them from reaching the core PAC bus.

• Multi-Layer Electronic Fault Protection: Sudden short circuits or current overloads on field loops stall operation. The BMXCPS3500 contains independent secondary overvoltage, overload, and short-circuit protection circuits that instantly isolate electrical faults to safeguard the rack hardware. An internal, primary-side fuse adds a final defensive layer against massive grid anomalies.

• Microbreak and Grid Transient Resiliency: Unstable power grids introduce micro-cuts that reset controllers. The internal energy reservoirs of this module provide 1 millisecond of absolute immunity to microbreaks, maintaining continuous backplane power during brief voltage drops. High insulation resistance (>= 100 MOhm) further shields downstream components from high-frequency grid noise.

• Ruggedized Environmental Housing: Engineered for unconditioned industrial environments, the card limits maximum power dissipation to 8.5 W, reducing heat buildup within sealed enclosures. A specialized TC protective treatment (tropicalization) prevents moisture corrosion, allowing the IP20 hardware to operate continuously from 0°C up to 60°C.

FAQs

• Is this BMXCPS3500 power supply a brand new original unit?

  Yes. We supply this module exclusively as a 100% brand new, original factory unit. It arrives factory-sealed in its original Schneider Electric industrial packaging, retaining all original production documentation and quality seals.

• Can this module fit the Ethernet-enabled BMEXBP series backplanes?

  No. The BMXCPS3500 supports standard Modicon X80 racks. It is explicitly incompatible with the hybrid Ethernet backplanes that carry the prefix code "BMEXBP..02". Verify your rack model prefix before executing the installation.

• How does the module display its real-time operating status?

  The front face features a dual-LED physical diagnostic layout. A green "rack voltage OK" LED confirms active, stabilized backplane power, while a separate green "sensor voltage" LED confirms safe operation of the 21.6 W field sensor loop.

• What function does the front mechanical button provide?

  The module houses a front-facing RESET push-button. Pressing this mechanical switch triggers a cold restart of the rack system, allowing maintenance technicians to clear temporary software locks or re-initialize hardware states directly at the enclosure without toggling main line breakers.
