ABB 1MRB150038R1 Power Supply Module

I. Positioning and Applications

• Series Affiliation: Power Supply Module of ABB AC 500 series PLC, serving as the core power supply component of the AC 500 system to provide stable DC power for devices such as CPU, I/O modules, and communication modules in the rack.
• Core Functions:

• Provides reliable 24 VDC power for industrial automation control systems, supporting single-power or redundant configurations.

• Suitable for scenarios with high requirements for power continuity, such as energy, chemical, and manufacturing industries, and can resist power grid fluctuations and transient interferences.

II. Technical Parameters and Characteristics

1. Input Specifications

• Voltage Range:

• AC version: 85–264 VAC (wide range adapts to global power grids), 50/60 Hz;

• DC version: 24–110 VDC (supports battery or DC bus power supply).

• Input Current: Typical value of 1.5–3 A for AC input (varying with output power).

• Protection Functions: Built-in overvoltage, undervoltage, and surge protection, capable of withstanding transient power grid fluctuations (such as lightning strikes and switching transients).

2. Output Specifications

• Output Voltage: 24 VDC (voltage regulation accuracy ±1%) to ensure stable module operation.

• Output Power: Typical value of 100 W (can drive 8–12 I/O modules, specifically depending on the load).

• Ripple Noise: ≤30 mV (low-noise design suitable for precision electronic components).

3. Electrical Characteristics

• Efficiency: ≥90% (high-efficiency design reduces heat generation and energy consumption).

• Isolation: Electrical isolation between input and output (isolation voltage 500 VAC) to prevent interference feedback.

• Short-Circuit Protection: Supports output short-circuit and overload protection, with automatic recovery after fault elimination.

III. Functional Highlights and Technical Features

1. Power Management and Reliability

• Enhanced Redundant Configuration: Can be connected in parallel with another 500PSM03a module to achieve "primary-backup automatic switching" through redundant modules, with a switching time<10 ms in case of primary power failure to ensure uninterrupted system operation.

• Real-Time Monitoring: Displays status through module panel LED indicators (Power, Fault, Redundancy), supporting fault early warning; voltage and current data can be monitored via Control Builder AC 500 software.

2. Environmental Adaptability

• Operating Temperature: -25°C to +60°C (wide-temperature design adapts to high and low temperatures in industrial sites).

• Protection Level: IP20 (dustproof when rack-mounted, requiring use with a cabinet).

3. Installation and Maintenance

• Installation Method: Directly inserted into the power slot of the AC 500 system rack, powered via the backplane bus, and supports hot-swapping (requires software configuration permission).

IV. Typical Application Scenarios

V. Interfaces and Wiring Examples

1. Hardware Interface Layout

• Input Interface: 4-pin terminal block (AC input: L1, N, PE; DC input: +, -, PE), supporting anti-reverse connection design.

• Output Interface: Powers rack modules via the backplane bus, with no external output terminals.

• Status Indication:

• Power (green): Illuminates when power is normal;

• Fault (red): Illuminates when input is abnormal or overloaded;

• Redundancy (yellow): Indicates primary-backup status in redundant mode.
