The Westinghouse 5X00501G01 is a redundant power supply module specifically engineered for Emerson’s Ovation Distributed Control System (DCS). It provides stable, fault-tolerant DC power to critical Ovation components (controllers, I/O modules, and communication interfaces), ensuring uninterrupted operation in high-availability industrial environments. Below is a detailed technical overview based on distributor specifications and Ovation system documentation:
- Brand & Model: Westinghouse (Emerson) 5X00501G01
- Type: Industrial-Grade Redundant Switching Power Supply Module
- System Compatibility: Exclusive to Emerson Ovation DCS (matches Ovation I/O racks, 5X00481G01 controllers, and auxiliary components)
- Certifications: CE, UL 508, CSA C22.2 No. 14, ATEX Zone 2 (compliant with industrial safety, EMC, and hazardous environment standards)
- Primary Function: Converts AC input to regulated DC power; supports 1+1 redundancy (two internal power supplies) to eliminate single points of failure in Ovation systems.
- Input Voltage Range: 85–264 VAC (wide-range, single-phase, 50/60 Hz) – compatible with global power grids
- Input Current: 3.5 A (max) at 85 VAC; 1.5 A (max) at 264 VAC
- Input Protection: Over-voltage protection (OVP, 300 VAC max), under-voltage lockout (UVLO, 75 VAC min), and surge protection (10 kV ESD)
- Output Voltage: Regulated 5 VDC (nominal) – optimized for Ovation controller power 需求；adjustable ±2% via trim pot
- Total Output Current: 40 A (continuous) – split between two redundant internal supplies (20 A per supply)
- Output Regulation: ±0.5% load regulation (ensures stable voltage despite varying load from I/O modules)
- Ripple & Noise: ≤ 20 mVpp (measured at full load, 20 Hz–20 MHz) – minimizes interference with sensitive control circuits
- Output Protection: Over-current protection (OCP, 22 A per supply), over-temperature protection (OTP, 95°C max), and short-circuit protection (auto-recovery)
- Efficiency: ≥ 90% at full load (5 VDC, 40 A) – meets ENERGY STAR® industrial efficiency standards
- Redundancy Mode: 1+1 hot redundancy – if one internal supply fails, the other automatically takes over (switchover time < 1 ms, no power interruption)
- Dimensions: 19.0 cm (W) × 12.7 cm (H) × 25.4 cm (D) – fits standard Ovation 6U rack slots (compatible with Ovation I/O rack enclosures)
- Weight: ~3.8 kg (includes heat sinks and redundant components)
- Mounting Type: Rack-mounted (front-panel latches for secure installation; hot-swappable for maintenance without system shutdown)
- Enclosure Material: Cold-rolled steel (corrosion-resistant, with powder-coated finish) – protects internal components from industrial dust and impact
- Cooling Method: Forced-air cooling (2 built-in 40 mm fans, temperature-controlled; fan failure alarm via DCS)
- Operating Temperature: -10°C to +60°C (suitable for control rooms, outdoor cabinets, and industrial facilities)
- Storage Temperature: -40°C to +85°C
- Humidity: 5%–95% RH (non-condensing) – no performance degradation in high-moisture environments (e.g., water treatment plants)
- Altitude: Up to 3000 meters (derate output current by 5% for every 1000 meters above 1000 meters)
- EMI/RFI Compliance: EN 55022 Class A (emissions), EN 55024 Class A (immunity) – resists interference from nearby motors, drives, or power cables
- Power (PWR): Green LED (per internal supply) – steady on = supply active; off = supply fault
- Redundancy (RED): Green LED – steady on = redundancy active (both supplies healthy); flashing = one supply faulty
- Fault (FLT): Red LED – steady on = over-temperature/over-current; flashing = input voltage out of range
- Fan Status (FAN): Amber LED – steady on = fans healthy; off = fan failure
- Diagnostic Output: Dry contact relay (Form C) – triggers DCS alarm for critical faults (e.g., both supplies failed, fan failure)
As a redundant power source, the 5X00501G01 is critical for Ovation DCS in industries where downtime is costly:
- Power Generation: Powers turbine controllers, boiler safety systems, and emissions monitoring modules in fossil/nuclear power plants.
- Oil & Gas: Supplies power to refinery process controllers, pipeline flow meters, and offshore platform automation systems.
- Chemical & Petrochemical: Supports batch reactor controllers and safety interlock modules (e.g., pressure relief valve controls).
- Water & Wastewater: Powers pump control modules, level sensors, and treatment process I/O devices.
- Wiring:
- Input: Terminal block for 85–264 VAC (L, N, PE ground) – accepts 10–14 AWG wire
- Output: Terminal block for 5 VDC (positive, negative, common ground) – accepts 8–12 AWG wire
- Grounding: Mandatory PE connection (≤ 5 Ω ground resistance) for safety and EMI protection
- Compatibility:
- Works with all Ovation controllers (e.g., 5X00481G01) and I/O modules (e.g., 1C31233G04, 5X00119G01)
- Requires Ovation System Power Distribution Unit (PDU) for distributing power to multiple rack components
- Distributors: Authorized Emerson partners (e.g., Amikon, 6gcontrols, RunToElectronic) – new, refurbished, and spare units available
- Warranty: 2 years (standard) for new units; 1 year for refurbished units (includes fan replacement coverage)
- Technical Support: Emerson provides firmware updates (if applicable), wiring diagrams, and troubleshooting guides via the MyEmerson portal; 24/7 phone support for critical faults
- Redundancy Setup: Requires two independent AC input feeds (from separate UPS systems) to maximize fault tolerance – avoid single AC source for both internal supplies.
- Maintenance: Replace faulty internal supplies or fans within 72 hours of alarm to restore full redundancy.
- Documentation: For exact pinouts, load curves, and redundancy configuration steps, refer to Emerson’s Ovation 5X00501G01 Redundant Power Supply Manual.
This module combines high efficiency, robust redundancy, and seamless Ovation integration, making it essential for mission-critical industrial systems where power reliability directly impacts safety and productivity. Always follow Emerson’s installation guidelines and local electrical codes.
