It mounts in the dedicated power supply slots (left side of the rack) and converts 125V DC station battery power to the regulated DC voltages required by the CPU, communications modules, and I/O cards. This module provides 300W total capacity, sufficient for fully loaded racks with high-power modules. The IC698PSD300 features reverse polarity protection and robust input filtering for reliable operation in industrial DC power systems. An internal fan provides active cooling, and the module supports hot-swap when installed in redundant configurations. This unit is new surplus, factory-sealed in original GE packaging. RX7i components remain widely deployed in power generation, substations, and heavy industry; contact us for current stock and firm pricing. GE IC698PSD300 Frequently Asked Questions (FAQ) Q: What’s the difference between IC698PSD300 and IC698PSA100E? A: Two major differences: Input voltage: IC698PSD300 is 125V DC; IC698PSA100E is 120/240V AC Output power: IC698PSD300 is 300W; IC698PSA100E is 100W The IC698PSD300 is designed for plants with 125V DC battery systems (common in power plants, substations, and heavy industry). The AC version is for standard plant power. They are not interchangeable—putting DC into an AC supply destroys it instantly, and vice versa. Choose based on your plant’s power infrastructure. Q: Why would I need a 300W supply instead of the 100W version? A: The GE IC698PSD300 provides three times the power of the 100W supplies. You need it when: Your RX7i rack is fully loaded with many I/O modules You have high-power modules (analog, high-speed counter, communications) You’re running multiple racks from one supply (with expansion) You want 20-30% headroom for future expansion In one power plant, we had a rack with 16 analog output modules driving I/Ps—drew 280W. The handled it easily. The 100W supply would have overloaded instantly. Calculate your power budget. If you’re over 80W, consider the 300W. Q: Does the support redundant power supply operation? A: Yes. The RX7i rack accepts two power supplies in adjacent slots for redundancy. With two modules installed: Both power the backplane simultaneously (load sharing via isolation diodes) If one fails, the other carries full load instantly Hot-swap the failed unit without rack shutdown Redundancy requires external isolation diodes (typically built into the rack or external diode modules). The has internal protection, but for true redundancy, you need the rack’s redundant power supply kit or external diode assemblies. In critical applications, this is non-negotiable. Q: What do the front panel LEDs indicate on the? A: The GE IC698PSD300 has multiple status LEDs: INPUT OK (green): 125V DC input present, within range PWR OK (green): Output voltages within spec FAULT (red): Output out of range, over temperature, fan failure, or internal fault If you see INPUT OK green but PWR OK off, the module has an internal failure—replace it. If FAULT red appears, check: Input voltage within 100-150V DC? Fan running? (blocked fan causes overtemp) Rack overloaded? (exceeded 300W) If all else OK, the likely has internal failure—replace. Q: Can I use the with 250V DC station battery systems? A: No. The is rated for 100-150V DC nominal (125V DC typical). Applying 250V DC will exceed the input capacitor ratings and destroy the module. If your plant uses 250V DC (common in older power plants and some substations), you need a DC-DC converter to step down to 125V DC, or a different power supply rated for 250V DC. GE offers other RX7i supplies for higher DC voltages. Check your station battery voltage before ordering. Q: What’s the reverse polarity protection on the? A: The GE IC698PSD300 includes internal reverse polarity protection. If you accidentally connect the 125V DC backwards, the module won’t be damaged—it just won’t power up. The protection circuit blocks reverse voltage. However, this is a last resort—always wire correctly. In power plants, we color-code DC wiring (red = positive, black = negative) and double-check before applying power. The protection saves you from mistakes, but don’t rely on it routinely. Q: What’s the typical failure mode for these high-power DC supplies? A: In my experience with RX7i systems in power plants: Fan failure—internal fan bearings wear after 5-7 years Capacitor aging—electrolytics dry out, especially in hot environments Input surge damage—lightning or switching transients on DC lines Overload failure—racks expanded beyond 300W without monitoring The is robust, but it’s a switching power supply running 24/7. In one substation, we replaced them every 10 years proactively. Fans are the weakest link—if you hear unusual noise, schedule replacement. Q: What’s the fan noise level on the? A: The has a temperature-controlled internal fan. At idle/cool, it’s barely audible. At full load in warm cabinets, it spins up and is noticeable—typical of high-power industrial supplies. The fan is essential for cooling at 300W output. If the fan fails, the supply will overheat and shut down within minutes at high load. In clean control rooms, fans last longer; in dusty plants, they fail sooner. Listen during rounds. Q: Can the power multiple RX7i racks? A: Not directly. The mounts in a specific rack and powers that rack’s backplane. For multiple racks, each rack needs its own power supply (or a special expansion power supply kit). The cannot power a second rack through expansion cables—the expansion cables carry signals, not power. Each rack must have its own power supply rated for its own load. In large systems, we calculate power per rack and size supplies accordingly. Q: Does the require configuration in the RX7i software? A: No. The GE IC698PSD300 is hardware-only—no software configuration. The RX7i backplane automatically detects its presence and power capability. However, the CPU monitors supply status via the backplane. If you add a second supply, the CPU sees it and reports redundancy status in the diagnostic logs. No programming required—just install and power up. Q: What’s the hold-up time on the, and why does it matter? A: Hold-up time is how long the keeps outputs regulated after DC input power drops. Spec is 10 ms minimum at full load. That’s enough to ride through most brief interruptions and switching transients. If DC drops longer than 10 ms, the supply shuts down gracefully—CPU gets a power-fail warning and can execute shutdown logic. In DC-powered systems (battery-backed), hold-up time matters less because batteries provide continuous power. But for momentary dips, 10 ms covers most events. Q: What’s the difference between and IC698PSD300A? A: The “A” suffix typically indicates a hardware revision with: Updated component sourcing Enhanced EMC protection Improved fan or thermal management Longer lifecycle availability The (no suffix) is the original version; IC698PSD300A is a later revision. In most cases, they’re interchangeable, with the “A” being preferred for new installations. Always verify with your system documentation. In critical applications, we match revisions exactly. For spares, the “A” version is usually fine to replace an original non-A.
