Product Overview

The Schneider Electric BMXCPS3020 functions as the primary DC-to-DC power conversion engine for the Modicon X80 platform. This high-performance module provides 30W of regulated secondary power to drive processors, I/O modules, and communication adapters within M340 and M580 PAC racks. Designed for versatility, the BMXCPS3020 handles a wide input range from 24V to 48V DC, making it an essential component for infrastructure relying on station battery banks or telecommunications power standards. We offer this unit as 100% Brand New and Original, ensuring maximum uptime for your critical control architecture.

Engineering Advantages

Extended DC Input Flexibility: The BMXCPS3020 operates across a broad DC voltage spectrum (18V to 62.4V). This eliminates the need for external voltage converters when integrating PACs into 48V battery systems commonly found in power utilities and remote telecommunications sites.
Stable Hold-up Performance: A 10ms hold-up time ensures that the M580 or M340 CPU remains operational during momentary voltage drops or switching transients. This feature prevents nuisance system resets and maintains data integrity during unstable power events.
Integrated Fault Monitoring: The module features a volt-free alarm relay. This allows engineers to hardwire a physical status signal directly into a safety circuit or a secondary monitoring system, providing instant notification if rack power fails.
Advanced Thermal Stability: Optimized for industrial environments, the module limits power dissipation to less than 8.5W. This high efficiency reduces heat buildup within the control cabinet, extending the life of adjacent logic and I/O modules.
Robust Isolation Barrier: With isolation resistance exceeding 100 MΩ, the BMXCPS3020 protects sensitive backplane electronics from field-side surges and ground loops. This electrical separation ensures the long-term reliability of high-speed communication across the X80 rack.

FAQs

Can I use the BMXCPS3020 in a redundant power supply rack?

No. The BMXCPS3020 is a standard power supply module. For redundant power configurations in M580 systems, you must use the BMXCPS4002 (AC) or BMXCPS3522 (DC) redundant models along with a redundant backplane.

Does the module provide power for field sensors connected to I/O modules?

The module provides 0.9A at 24V DC to the backplane, which powers internal I/O circuitry and rack communication. However, for high-current field devices and sensors, you typically require a separate external field power supply to avoid overloading the PAC backplane.

What happens if the internal fuse blows?

The BMXCPS3020 features an internal non-serviceable fuse for safety. If the fuse fails due to a catastrophic internal fault, you must replace the module. We provide these units as 100% Brand New, ensuring they arrive with intact protection circuits and factory-fresh components.

How do I monitor the "Health" of the power supply?

You can monitor the status via the front panel LEDs (green "OK" light) or by utilizing the built-in alarm relay. In the Modicon software (Control Expert), the system bit %S10 also indicates the status of the rack power supply.
