Advantages and Features

The primary advantage of the GE IC698PSD300 lies in its high 300-watt output capacity, enabling it to power even the most densely populated RX7i racks with multiple high-power modules. By utilizing the GE IC698PSD300, system designers can maximize I/O capacity and incorporate power-hungry modules such as high-speed counters, motion controllers, or communication processors without concerns about exceeding power supply limitations. The DC input configuration of the GE IC698PSD300 makes it ideal for installations where DC power distribution is standard, such as in telecommunications, transportation, or certain industrial applications with centralized DC backup systems. Comprehensive protection circuits built into the GE IC698PSD300 safeguard both the power supply itself and the expensive modules it powers, automatically shutting down in the event of overcurrent, overvoltage, or overtemperature conditions. The diagnostic LEDs on the front panel of the GE IC698PSD300 provide immediate visual indication of power status, simplifying troubleshooting when problems arise. Furthermore, the GE IC698PSD300 features hold-up time that maintains regulated output through brief input power interruptions, allowing the control system to ride through minor disturbances without disruption.

Application Cases in Application Fields

The high power capacity and DC input flexibility of the GE IC698PSD300 make it essential across numerous industrial applications requiring RX7i-based control systems with substantial power demands.

• Railway and Transit Systems: In a railway signaling and control application, the GE IC698PSD300 operates directly from the facility’s 125 VDC station battery plant, powering RX7i racks that monitor track circuits and control switches without requiring AC power conversion.

• Telecommunications Facilities: At a major telecom central office, the GE IC698PSD300 draws power from the -48 VDC telecom plant (with appropriate input rating) to power RX7i controllers managing backup generators, HVAC, and facility monitoring systems.

• Utility Substation Automation: In an electrical substation, the GE IC698PSD300 operates from the station battery, powering RX7i racks that monitor breaker status, control switchgear, and communicate with SCADA systems even during AC power outages.

• Marine and Offshore: On a ship or offshore platform with DC distribution systems, the GE IC698PSD300 provides reliable power for RX7i controllers managing propulsion, power generation, and auxiliary systems.

• Heavy Industrial Manufacturing: In a steel mill or automotive plant with centralized DC power distribution, the GE IC698PSD300 powers dense RX7i racks controlling complex production lines without requiring individual AC/DC conversion for each rack.

Comparison with Competing Products

When compared to power supplies from competing platforms such as the Allen-Bradley 1756-PSCA2 (ControlLogix DC input) or the Siemens PS 407 (S7-400 DC version), the GE IC698PSD300 offers specific advantages for users invested in the RX7i ecosystem. While Allen-Bradley power supplies provide similar functionality, the GE IC698PSD300 offers higher output capacity on the critical +5 VDC rail compared to many competitors, supporting larger I/O counts and more complex modules per rack. Compared to Siemens power supplies requiring specific input voltage variants, the GE IC698PSD300 is designed for the DC voltages common in North American utility and transportation applications. For facilities with existing GE infrastructure and DC power distribution, the GE IC698PSD300 provides the most direct power solution without the need for external AC/DC converters or power conditioners.

Comparison with Related Models (IC698PSA100E)

When compared to the previously discussed GE IC698PSA100E (100-watt AC-input power supply), the GE IC698PSD300 represents a significant upgrade in both power capacity and input voltage type. While the GE IC698PSA100E is suitable for smaller racks or applications with modest power requirements, the GE IC698PSD300 provides three times the output power, supporting heavily loaded racks with multiple high-power modules. The DC input capability of the GE IC698PSD300 also makes it suitable for applications where the GE IC698PSA100E would require an external AC source. Users should select between these models based on their specific power requirements and available input power type.

Selection Suggestions and Precautions

When selecting the GE IC698PSD300 for your application, first verify that your facility’s DC power source voltage matches the input rating of the module (typically 125 VDC, but verify with the specific datasheet). Calculate the total power requirements of all modules installed in the RX7i rack to ensure the combined load does not exceed the 300-watt capacity of the GE IC698PSD300, paying particular attention to the +5 VDC current draw. When installing the GE IC698PSD300, ensure that the DC supply wiring is properly sized, fused, and protected according to electrical codes, and that polarity is observed to prevent damage. Verify that the rack is mounted with adequate clearance for convection cooling and that ambient temperatures remain within the specified range, derating the maximum output if operating above 50°C. When replacing the GE IC698PSD300 in a live system, always power down the rack completely before removal and installation, as hot-swapping power supplies is not supported and could damage both the power supply and the backplane. Ensure that the DC source is de-energized and locked out before handling the GE IC698PSD300 wiring. Finally, periodically inspect the cooling vents of the GE IC698PSD300 for dust accumulation and clean as necessary to prevent overheating and premature failure.
