ABB 500PSM03a 1MRB 150038 R1 894-030375D 136-011100H Power Supply Module

Voltage Range:

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).

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).

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.

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.

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).

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).

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:

Confirm that the input voltage matches the module version (AC/DC cannot be mixed). Strictly distinguish between neutral and live wires (AC) or positive and negative poles (DC) during wiring, and the PE wire must be reliably grounded.

For redundant configurations, enable the "power redundancy" function in Control Builder software and set module priorities (primary module supplies power first).

If the Fault light is on:

Clean the dust from the module's cooling holes quarterly to avoid overheating protection due to poor heat dissipation;

For redundant systems, it is recommended to conduct primary-backup switching tests every six months (can be forced via software) to ensure normal redundant functionality.

High reliability: Wide-range input, strong anti-interference capability, and multiple protection mechanisms adapt to complex industrial power grids;

Flexible redundancy: Built-in redundancy control enables primary-backup automatic switching without additional modules, reducing system downtime risks;

High efficiency and energy saving: ≥90% conversion efficiency reduces energy consumption, suitable for long-term continuous operation scenarios.
