Schneider Electric BMXCPS3020 Modicon X80 High-Power DC Power Supply Module

Product Overview

The Schneider Electric BMXCPS3020 drives regulated high-capacity electrical power directly to standard Modicon X80 automation backplanes. Running on an isolated 24 V to 48 V DC primary input network, this module converts wide-range direct current into two highly stabilized secondary rails. It energizes high-density I/O arrays, advanced communications processors, and main CPUs, serving as the primary electrical backbone for heavy industrial substations, oil and gas telemetry, and transport infrastructure.

Technical Specifications

Engineering Advantages

• Wide-Range Isolated DC Input Stage: Battery banks and remote DC grids experience major voltage swings. The BMXCPS3020 accommodates an expansive input window from 18 V DC up to 62.4 V DC while maintaining an isolated 1500 V dielectric barrier between the primary inputs and internal backplane logic. This design shields sensitive microprocessors from line surges and floating ground hazards.

• Boosted Current Output for High-Density Racks: Large I/O configurations cause standard power modules to sag. This unit answers that demand by outputting a robust 4.5 A on the 3.3 V DC logic rail (15 W) and 1.3 A on the 24 V DC system rail (31.2 W). This elevated power overhead eliminates the need to install additional supplementary racks or split power zones.

• Advanced Secondary Fault Tripping: Downstream wiring errors or shorted field modules can disable a controller. The BMXCPS3020 utilizes independent secondary overvoltage, overload, and short-circuit protection circuits that instantly respond to electrical anomalies, protecting your rack hardware from thermal damage.

• Ruggedized Environmental Performance: Built to thrive inside harsh control cabinets, the module limits its maximum power dissipation to 8.5 W, dropping internal cabinet temperatures. Equipped with a TC protective treatment (tropicalization), the card repels moisture and airborne contaminants while resisting 3 gn vibrations and 30 gn mechanical shock.

• Integrated Microbreak Immunity: Fluctuating power grids can cause brief drops in line voltage. The internal energy storage of this supply bridges microbreaks up to 1 ms, preventing unexpected PLC resets and data corruption during localized grid disturbances.

FAQs

• Is this BMXCPS3020 power supply a brand new original unit?

  Yes. We supply this product strictly as a 100% brand new, original factory unit. It arrives sealed in the authentic Schneider Electric box with all current factory certifications and documentation intact.

• Can I use this power supply on both 24V DC and 48V DC battery systems?

  Yes. The internal auto-ranging circuitry natively handles isolated inputs from 24 V to 48 V DC (and handles limits from 18 V to 62.4 V DC) without requiring any hardware jumper adjustments or software re-configurations.

• Does this module support the newer BMEXBP Ethernet backplanes?

  No. The BMXCPS3020 works with standard Modicon X80 racks. It is explicitly incompatible with the hybrid Ethernet-enabled backplanes that carry the prefix code "BMEXBP..02". Always check your rack model before installation.

• What are the cable distance limitations for wiring the primary power?

  To avoid excessive line voltage drop, follow the manufacturer limits based on copper wire cross-sections: limit distances to 32.8 feet (10 m) when using 1.5 mm² (0.002 in²) power cables, or extend up to 49.2 feet (15 m) when using 2.5 mm² (0.004 in²) conductors.
