ABB PHARPS32200000 F8-G2B9B3B6

Description

Product Description

The ABB PHARPS32200000 F8-G2B9B3B6 is a sophisticated Redundant Power Supply System designed for high-availability industrial automation and control cabinets, particularly those housing critical ABB components like PLCs, drives, or process controllers. This system, the ABB PHARPS32200000 F8-G2B9B3B6, integrates two hot-swappable power supply modules in a single chassis to provide N+1 redundancy, ensuring continuous operation even if one power supply fails. Its primary function is to convert incoming AC line voltage (typically single or three-phase) into a regulated, isolated 24V DC output, which is the standard control voltage for sensors, relays, and electronic modules. The robust design of the ABB PHARPS32200000 F8-G2B9B3B6 prioritizes reliability, diagnostics, and easy maintenance for mission-critical applications.

Product Parameters

The technical specifications for the ABB PHARPS32200000 F8-G2B9B3B6 redundant power system define its capacity and resilience:

• System Type: Redundant Power Supply System (24V DC Output).

• Input Voltage: Designed for a wide-range AC input, typically 100-240V AC, 1-phase, 50/60 Hz (specifics may vary by variant).

• Output Voltage: Nominal 24V DC, regulated.

• Output Current/Power: Each internal power supply module has a specific current rating (e.g., 20A). The total system output is the rating of one module, with the second providing redundancy. The “322” in the part number may indicate a 20A or 40A total system capacity.

• Redundancy Method: True hot-swap, load-sharing redundancy with OR-ing diodes or MOSFETs to isolate a failed unit.

• Protection Features: Includes input over-voltage protection, output over-current protection, short-circuit protection, and over-temperature protection.

• Monitoring and Diagnostics: Features comprehensive LED status indicators for input OK, output OK, load share, and failure. May include relay contacts for remote alarm signaling (e.g., “Supply Fail”).

• Mounting: Designed for standard DIN rail mounting (likely top-hat rail).

• Connections: Screw terminal blocks for input power, output power, and alarm contacts.

Advantages and Features

The ABB PHARPS32200000 F8-G2B9B3B6 offers significant advantages for system uptime:

• Maximum System Availability: The core advantage of the ABB PHARPS32200000 F8-G2B9B3B6 is its redundant architecture, which eliminates the power supply as a single point of failure, dramatically increasing the mean time between failures (MTBF) for the entire control system.

• Hot-Swappable Maintenance: Power supply modules can be replaced without tools and without interrupting the 24V DC output to the load. This allows for proactive maintenance and immediate replacement of a faulty unit with zero downtime.

• High Efficiency and Low Heat Dissipation: Modern switching power supply design ensures high energy efficiency, reducing operating costs and thermal stress within the control cabinet.

• Comprehensive Diagnostics: Clear visual LEDs and potential alarm contacts provide instant local and remote status, enabling fast fault identification and response.

• Robust Industrial Design: Built to withstand typical industrial environments with regards to temperature, humidity, vibration, and electrical noise.

Application Cases in Industry

This redundant power system is essential in any industry where control system uptime is critical:

• Automotive Manufacturing: Powers the entire safety and control system of a robotic welding or painting cell, where a power loss would cause massive production disruption.

• Oil & Gas (Offshore Platforms): Provides clean, reliable power to the PLCs and safety systems controlling wellhead and process equipment, where reliability is paramount for safety and production.

• Pharmaceutical Batch Processing: Ensures uninterrupted power to the process control system during a sensitive and valuable batch reaction, where a shutdown could ruin the product.

• Data Center Infrastructure: Used to power the control systems for cooling (CRAC units) and power distribution (PDUs), where continuity is essential.

• Water/Wastewater SCADA: Provides fault-tolerant power to the main RTU/PLC at a central treatment plant, ensuring continuous monitoring and control of the purification process.

Comparisons with Competing Products

When compared to using two separate single power supplies wired for redundancy or non-redundant systems, the ABB PHARPS32200000 F8-G2B9B3B6 provides an integrated, superior solution:

• Integrated vs. Discrete Redundancy: The ABB PHARPS32200000 F8-G2B9B3B6 is a pre-engineered, tested system with integrated load-sharing, monitoring, and alarm logic. Wiring two standalone supplies for redundancy is less reliable, more complex, and lacks unified diagnostics.

• Superior Form Factor and Simplicity: It combines two supplies and all redundancy circuitry into a single, compact DIN-rail unit, saving space and simplifying cabinet layout compared to mounting and wiring two individual units plus external redundancy modules.

• Vendor-Quality Assurance: As an ABB product, it meets consistent quality and performance standards. Mixing and matching different brands of power supplies in a redundant setup can lead to compatibility issues in load-sharing or protection coordination.

• Global Support and Consistency: Specifying the PHARPS32200000 F8-G2B9B3B6 ensures the same certified component is used globally in a multinational project, simplifying spare parts strategy and technical support.

Selection Suggestions and Precautions

Proper sizing and installation are key to realizing the benefits of redundancy:

1. Accurate Load Calculation: Calculate the total 24V DC current required by all connected devices (PLCs, I/O, sensors, relays). Select the ABB PHARPS32200000 F8-G2B9B3B6 model so that the output rating of one power supply module exceeds this total load. The second module is for redundancy, not for doubling capacity.

2. Source from Independent Feeders: For true redundancy, connect the two input power terminals of the PHARPS32200000 to two separate, independent AC branch circuits. If connected to the same circuit, a breaker trip will still cause a total system failure.

3. Use Appropriate Input Protection: Install the correctly rated circuit breaker or fuse on the AC input side of each power supply input as per the manual. Do not rely solely on the unit’s internal protection.

4. Monitor Alarm Contacts: Wire the integrated alarm contacts (if available) to a supervisory system (SCADA, BMS, or a beacon) to provide remote notification of a power supply failure, even if the output is still live.

5. Observe Derating at High Temperature: Power supply output capacity decreases at high ambient temperatures. Ensure the cabinet temperature where the PHARPS32200000 is installed is within its specified operating range for full performance.
