1P00028G01 Ovation Power Supply Module (Industrial-Grade DCS Component)

The 1P00028G01 represents Emerson's commitment to power integrity in mission-critical distributed control environments. Engineered for continuous operation in harsh industrial settings, this power supply module transforms unstable grid power into precision-regulated DC outputs that sustain Ovation controllers, I/O subsystems, and network infrastructure through electrical disturbances that would cripple lesser equipment.

Process industries cannot tolerate control system failures. Whether you're managing catalytic crackers, bioreactor batches, or municipal water treatment, the 1P00028G01 provides the electrical foundation that keeps automation systems responsive during voltage transients, harmonic pollution, and momentary outages. Its active filtering and regulation circuits maintain output stability within ±1% even when input voltage swings ±15%.

Built for engineers who understand that uptime begins with clean power, this module integrates seamlessly into Ovation chassis architectures while offering hot-swap serviceability and parallel redundancy options that eliminate single points of failure.

Core Capabilities & Technical Advantages

→ Universal Input Compatibility: Auto-ranging 100-240VAC operation eliminates voltage selection switches and adapts instantly to global power standards, simplifying multi-site deployments and spare parts inventory.

→ Multi-Rail Output Architecture: Delivers isolated +5VDC, ±12VDC, and +24VDC rails with independent current limiting, supporting diverse Ovation card types from analog I/O to high-speed communication processors.

→ Extended Holdup Performance: Maintains output regulation for minimum 20ms after AC loss—sufficient time for backup systems to engage or for controlled shutdown sequences to complete without data corruption.

→ Thermal Resilience: Operates reliably from -10°C to +60°C ambient with intelligent fan speed modulation that reduces acoustic noise during light loads while maximizing cooling during peak demand.

→ Predictive Diagnostics Integration: Modbus-accessible telemetry streams internal temperature, load current, and fan RPM to AMS Suite, enabling condition-based maintenance strategies that prevent failures before they occur.

✓ Hot-Swap Architecture: Replace failed units without de-energizing the Ovation rack—critical for 24/7 process industries where scheduled downtime costs millions per hour.

Industry Application Profiles

Refining & Petrochemicals: In hydrocracker units processing 50,000 barrels per day, the 1P00028G01 powers Ovation controllers managing reactor temperature cascades, hydrogen recycle compressors, and fractionation column controls. When electrical storms trigger grid voltage sags, the PSU's input surge protection and holdup time prevent nuisance trips that could force emergency shutdowns costing $2M+ in lost production.

Pharmaceutical & Biotech: Cleanroom HVAC systems in sterile manufacturing suites rely on these modules for uninterrupted control of differential pressure, temperature, and humidity—parameters that must remain within ±0.5°C and ±2% RH to maintain FDA validation. Low EMI emissions (EN 55011 Class A) prevent interference with HPLC analyzers and mass spectrometers operating nearby.

Power Generation: Combined-cycle plants use 1P00028G01 modules in turbine control systems where loss of power to vibration monitors or flame detectors would trigger protective trips. Conformal coating on circuit boards resists condensation in outdoor equipment shelters, extending service life beyond 15 years in coastal environments.

Water & Wastewater: Remote lift stations and treatment plants deploy these PSUs in NEMA 4X enclosures where temperature extremes, humidity, and corrosive atmospheres challenge conventional electronics. Wide input voltage tolerance accommodates weak rural grids and generator-supplied power during utility outages.

Mining & Metals: Smelter control rooms subject equipment to electromagnetic interference from arc furnaces and induction heaters. The 1P00028G01's input filtering and shielded construction maintain clean DC outputs despite conducted and radiated noise that exceeds industrial EMC test limits.

Electrical Specifications & Selection Criteria

Selection Guidance: Calculate total DC load by summing current requirements of all Ovation cards in the chassis. For N+1 redundancy, install one additional PSU beyond minimum requirement. In high-availability applications (refineries, pharma), specify 2N redundancy with automatic load sharing.

Advanced Integration Features

Parallel Redundancy with Active Load Sharing: Install multiple 1P00028G01 modules in the same chassis for fault tolerance. Internal current-sharing circuits automatically balance load across all units. If one PSU fails, remaining modules increase output proportionally to maintain system voltage—no manual intervention required.

Remote Monitoring via AMS Suite: Connect to Emerson's Asset Management System for real-time visibility into PSU health metrics. Set alarm thresholds for output current approaching rated capacity, internal temperature exceeding 70°C, or fan speed deviating from expected curves. Trend data over months to identify gradual degradation before catastrophic failure.

Cybersecurity Considerations: While the 1P00028G01 itself has no network connectivity, its integration with AMS Suite requires secure configuration of Modbus TCP links. Follow IEC 62443 guidelines for industrial network segmentation, ensuring power system diagnostics traverse only trusted VLANs isolated from enterprise IT networks.

Frequently Asked Questions

Can the 1P00028G01 operate on generator power during utility outages?
Yes. The auto-ranging input and wide frequency tolerance (47-63 Hz) accommodate generator voltage and frequency variations typical during load transients. Ensure generator capacity exceeds PSU inrush current (25A peak for 5ms).

What is the maximum number of modules I can parallel in one chassis?
Up to four 1P00028G01 units can share load in a single Ovation chassis, providing 600W total capacity with 3N redundancy. Current-sharing accuracy is ±5% across all units.

How does the module protect against output short circuits?
Each DC rail has independent overcurrent protection with automatic restart. Short circuits trigger foldback limiting that reduces output to 10% of rated current, preventing damage while allowing fault clearance. Once the short is removed, the PSU auto-recovers within 2 seconds.

Is the 1P00028G01 suitable for hazardous area installations?
The module carries ATEX Zone 2 certification for installation in control rooms adjacent to classified areas. For Zone 1 or Division 1 locations, house the Ovation chassis in a purged enclosure meeting IEC 60079-2 requirements.

What maintenance intervals does Emerson recommend?
Inspect air filters quarterly in dusty environments; clean or replace as needed. Verify fan operation and listen for bearing noise annually. Capacitor-based designs like the 1P00028G01 benefit from load testing every 5 years to confirm holdup time remains within specification.

Can I retrofit this PSU into older Ovation systems?
The 1P00028G01 is backward-compatible with Ovation chassis manufactured since 2005. Verify your chassis has firmware version 3.5 or later to support hot-swap functionality. Contact our retrofit team for compatibility verification with pre-2005 systems.
