GE SR489-P5-LO-A20-E Product Specification
Product Overview: GE SR489-P5-LO-A20-E
The GE SR489-P5-LO-A20-E is a high-reliability industrial power supply module designed for mission-critical automation systems. Engineered by General Electric (GE), a leader in industrial power solutions, this module belongs to the SR489 series, renowned for its robust performance and precision voltage regulation. As a key component in PLC, DCS, and SCADA systems, the GE SR489-P5-LO-A20-E ensures stable power delivery to control cabinets, field devices, and network infrastructure, making it indispensable for industries requiring uninterrupted operation, such as oil and gas, power generation, and manufacturing.
Featuring a compact yet durable design, the GE SR489-P5-LO-A20-E integrates advanced switching technology to deliver 24 VDC output with minimal ripple and noise. Its wide input voltage range (85–264 VAC) and universal frequency compatibility (47–63 Hz) make it suitable for global applications, while the built-in active PFC (power factor correction) enhances energy efficiency. The module’s thermal design includes a low-speed fan for silent operation and passive cooling in lower-load scenarios, ensuring reliability in both standard and harsh environments (-20°C to +70°C operating temperature).
In automation architectures, the GE SR489-P5-LO-A20-E acts as a foundational element, providing clean power to critical components like controllers, I/O modules, and communication gateways. Its redundant configuration capability—allowing parallel operation with other SR489 series modules—mitigates the risk of power disruptions, a critical feature for systems with zero-tolerance for downtime. By combining high-efficiency power conversion with intelligent protection mechanisms (overvoltage, overcurrent, overtemperature), the module safeguards connected equipment and minimizes maintenance requirements, delivering long-term value for industrial operators.
