ABB PM150 3BSE003641R1

Description

Product Description

The ABB PM150 3BSE003641R1 is a dedicated, high-reliability power supply module designed for ABB’s AC 500 PLC platform, specifically intended for the PM5xx series of CPUs and their associated I/O base units. This component is not a generic power supply; it is an integral system module that converts the incoming AC mains voltage into the precisely regulated and filtered DC voltages required to power the PLC’s central processor, memory, and communication circuits. The primary function of the ABB PM150 is to provide a clean, stable, and protected power foundation for the entire control station, ensuring immunity from grid fluctuations and electrical noise that could cause data corruption or controller resets. Installing the ABB PM150 3BSE003641R1 is a fundamental requirement for energizing an AC 500 control station, forming the critical first link in the chain of reliable automation. Its design prioritizes compatibility and safety within the ABB ecosystem.

Technical Parameters and Features

• Device Type: System Power Supply Module for AC 500 PLC (PM5xx CPUs).
• Input Voltage: Typically accepts a wide-range AC input, such as 85-264 VAC, 47-63 Hz, allowing for global deployment without manual voltage taps.
• Output Specifications:
  • Primary Output: Provides the +24 VDC system bus power required by the CPU and any connected I/O modules in the base unit.
  • Rated Output Current: The “150” in PM150 suggests a nominal output power rating, likely in the range of 150W or a corresponding current output (e.g., 6.5A at 24V). The exact rating should be verified via the datasheet for article 3BSE003641R1.
• Protection Features: Includes standard safeguards such as overload protection, short-circuit protection, and overvoltage protection to prevent damage to the supply itself or the connected PLC components.
• Efficiency: High-efficiency switching design to minimize heat generation and energy loss.
• Status Indication: Equipped with LED indicators to show input power (AC OK) and output power (DC OK) status at a glance.
• Mounting: Plugs directly into the dedicated power supply slot on the left side of compatible AC 500 base units (e.g., PS501, PS507).
• Wiring: Features screw terminal blocks for secure connection of line (L), neutral (N), protective earth (PE), and the system power output.
• Certifications: Complies with relevant international safety (UL, CSA, CE) and EMC standards for industrial equipment.

Advantages and Key Features

• Guaranteed System Compatibility: The ABB PM150 3BSE003641R1 is engineered and tested specifically for the electrical characteristics and load profiles of the AC 500 platform. This ensures reliable start-up sequencing, proper voltage levels, and eliminates compatibility risks associated with generic power supplies.
• Compact and Integrated Design: Its plug-in design saves valuable panel space by integrating directly into the PLC base unit, eliminating the need for a separate DIN-rail mounted power supply, external wiring, and additional enclosures.
• Robust Power Conditioning: Provides excellent line and load regulation along with high noise rejection. This creates a “clean” power island for the sensitive PLC electronics, which is critical for stable operation in electrically noisy industrial environments.
• Simplified Installation and Maintenance: The modular, plug-in nature makes installation straightforward. In the event of a failure, the PM150 module can be replaced quickly without disturbing field wiring connected to the I/O modules.
• Predictable Performance and Support: As a genuine ABB component, it comes with assured performance specifications and access to ABB’s technical support, which is vital for troubleshooting and system validation.

Application Case Studies in Various Fields

• Packaging Machine Control Cabinet: An ABB PM150 module powers a PM581 CPU and a mix of digital and analog I/O modules in a base unit controlling a cartoning machine. Its clean power ensures reliable high-speed counting and sensor input reading.
• Water Treatment PLC Skid: Used as the main system power supply in a remote telemetry unit, the wide input range of the PM150 3BSE003641R1 tolerates unstable rural grid power, while its regulated output keeps the PLC and communication modules online.
• Factory Automation Cell: Powers a local AC 500 controller managing a robotic work cell. The power supply’s immunity to electrical noise from nearby servo drives and welders prevents nuisance faults in the PLC logic.
• Energy Management Subsystem: Provides reliable power to a data logging and control PLC on a compressor or generator skid, where the integrity of the control system is paramount for equipment safety.

Comparison with Competing Products

When compared to using a standard DIN-rail mount switching power supply, the ABB PM150 offers distinct system-level benefits:

1. Integrated System Component vs. External Add-On: The PM150 is a plug-in system component with a direct backplane connection. A generic DIN-rail supply is an external device requiring separate wiring to the PLC base unit, adding points of failure and not participating in the system’s integrated power management.
2. Optimized Performance: Its electrical characteristics (inrush current, hold-up time, ripple) are designed to match the PLC’s requirements. A generic supply might work initially but could cause brown-out resets or data corruption under certain load conditions.
3. Space and Wiring Efficiency: The integrated design of the ABB PM150 3BSE003641R1 saves a DIN-rail slot, reduces wiring complexity, and results in a cleaner, more professional panel layout.

Selection Advice and Important Notes

• Verify Base Unit Compatibility: Confirm that your specific AC 500 CPU base unit (e.g., PS501, PS507) is designed to accept the PM150 power supply module. Not all base units have an integrated power supply slot; some require external 24VDC.
• Perform a Load Calculation: Before installation, calculate the total 24VDC current consumption of all modules (CPU and any I/O in the base unit). Ensure the PM150‘s rated output current exceeds this total with a safety margin (typically 20-30%). Overloading the supply will cause it to shut down or overheat.
• Follow Electrical Safety Codes: Always connect the protective earth (PE) terminal. Ensure the AC line wiring is performed according to local electrical codes, using appropriate wire gauges and circuit protection (a fuse or circuit breaker) on the input side.
• Use as a System Supply Only: The ABB PM150 is designed to power the PLC backplane and internal electronics. It should not be used as a general-purpose 24VDC source for field devices like sensors or actuators. Use a separate, appropriately sized field power supply to avoid noise and load issues on the control system.
