Description

The EPRO SDM010 is a dual-redundant 24 VDC power supply module engineered by EPRO GmbH(now part of Baker Hughes)for use in high-availability condition monitoring and machine protection systems,particularly within the EPRO MMS6000 platform.Designed to power critical components such as vibration sensors(e.g.,PR6425),signal conditioners,and I/O modules,it ensures uninterrupted operation through active load sharing and automatic failover.

This rugged,rack-mounted power unit delivers stable,noise-free DC output with comprehensive protection features—making it essential for continuous monitoring of turbines,compressors,pumps,and other rotating machinery in energy,petrochemical,and industrial facilities.

Application Scenarios

At a combined-cycle power plant in Italy,an unplanned gas turbine trip occurred due to a single-point power failure in the legacy monitoring system’s PSU—causing a cascade shutdown that cost over€1.2M in lost generation and penalties.During the root-cause analysis,engineers specified the EPRO SDM010 as the replacement power solution for the upgraded MMS6000 rack housing PR6425 eddy-current probes and MMS6210 monitor cards.With its true 1+1 redundancy,the EPRO SDM010 now powers all modules with zero downtime during maintenance or component failure.In the first year of operation,the system achieved 99.999%availability,and the plant passed its ISO 55000 asset management audit with full compliance on power resilience.

Technical Principles and Innovative Values

Innovation Point 1:True Active Load Sharing–Unlike passive redundancy schemes,the EPRO SDM010 actively balances current between both power units,reducing thermal stress and extending service life—critical for 24/7 turbomachinery monitoring.

Innovation Point 2:Ultra-Fast Switchover–In the event of a module failure,the EPRO SDM010 transfers full load in under 10 ms—faster than the hold-up time of downstream monitors—ensuring no data loss or false trips.

Innovation Point 3:Integrated System Diagnostics–Each EPRO SDM010 provides a dry contact alarm output and front-panel LEDs that integrate into the MMS6000’s central status display,enabling predictive maintenance before power issues escalate.

Innovation Point 4:Universal Input&Global Compliance–Accepts both AC and DC mains worldwide,eliminating the need for region-specific variants—a key advantage in multinational asset portfolios.

Application Cases and Industry Value

In a Middle Eastern LNG compression train,six centrifugal compressors were retrofitted with EPRO MMS6000 systems powered by EPRO SDM010 modules.The site previously experienced intermittent sensor dropout during monsoon season due to voltage sags.After installation,the wide-input EPRO SDM010 maintained stable 24 VDC even during 80 VAC dips,ensuring continuous shaft vibration monitoring.Over two years,the facility reported zero compressor trips related to power instability,and maintenance teams used the remote alarm signal to schedule PSU replacements during planned outages—eliminating emergency callouts.

Another case in a European steel mill used the EPRO SDM010 to power eddy-current sensors on a 20 MW rolling mill motor.The unit’s robust EMC immunity prevented noise coupling from nearby variable-frequency drives,preservingµm-level displacement accuracy required for bearing health assessment.

Installation,Maintenance,and Full-Cycle Support

Installing the EPRO SDM010 requires insertion into a compatible MMS6000 chassis(e.g.,MMS6811)with secure backplane engagement.Connect AC or DC mains to the terminal block—no configuration is needed,as redundancy is hardware-managed.Ensure adequate ventilation;the unit can operate at full load up to 60°C ambient.For critical applications,install both EPRO SDM010 modules to enable true redundancy.

Maintenance involves periodic visual inspection of status LEDs and cleaning of ventilation slots.The remote alarm contact can be wired to a DCS for automated logging.If a module fails,it can be replaced under power without interrupting system operation—thanks to hot-swap support in the MMS6000 architecture.
