GE IC600PM507 750 W Rack Power Supply

Description

In any GE Series Six installation that has grown over the years, the original 500 W power supply eventually becomes the silent bottleneck: voltage rails start drooping under full load, the rack fault LED flickers randomly, and high-density 32-point cards or intelligent modules begin throwing intermittent errors that no one can reproduce on the bench. The GE IC600PM507 is the factory-direct 750 W replacement power supply specifically engineered for Series Six 10-slot and 15-slot I/O racks (and the central CPU rack when used with the appropriate mounting kit). It delivers clean, over-rated 5 V and ±15 V to every slot with enough headroom to support a fully loaded rack of modern high-density I/O without ever breaking a sweat.

Engineers reach for the GE IC600PM507 the moment the diagnostic log shows marginal 5 V (below 5.08 V under load), when new 32-point modules refuse to initialize, or when a plant expansion pushes the old PM500/PM501 beyond its nameplate. Instead of adding auxiliary supplies or splitting racks (both expensive and panel-space hungry), swapping in a GE IC600PM507 restores full margin in a single maintenance window. It is the single most effective upgrade you can perform on an aging Series Six system when the goal is long-term reliability without touching field wiring or logic.

The GE IC600PM507 mounts in the dedicated left-hand position of any standard Series Six I/O or CPU rack using the original captive hardware. It accepts universal 105–132 VAC or 210–250 VAC at 47–63 Hz (jumper-selectable) and converts it to regulated +5 V @ 90 A, +15 V @ 8 A, and –15 V @ 4 A with active current limiting and over-voltage crowbar protection on every rail. A front-panel voltmeter and four status LEDs (AC OK, +5 V OK, +15 V OK, –15 V OK) give immediate visual confirmation of health, while a Form-C relay contact on the front connector provides remote rack-fail annunciation to the SCADA or panel alarm system.

From the backplane perspective, it behaves identically to the original supplies but with roughly 50 % more capacity and significantly tighter regulation (±0.5 % vs the old ±2 %). That extra headroom is what lets today’s fully populated 15-slot racks (fifteen 32-point cards plus analog and intelligent modules) run cool and stable for another twenty years.

Dropping in a GE IC600PM507 immediately eliminates the low-voltage alarms that plague heavily loaded racks and stops the random resets that occur when the old 500 W supply hits its thermal limit on hot summer days. Plants routinely see mean time between rack faults jump from months to years after the swap. Because the supply includes remote sense lines that compensate for voltage drop across a tired backplane, even racks with slightly oxidized connectors regain full 5.15 V at the farthest slot—something the original supplies never had.

Maintenance teams love the built-in analog voltmeter and the fact that the output cables are the same length and connector style as the originals, so no rewiring is required. In terms of total cost of ownership, one GE IC600PM507 plus two hours of labor typically pays for itself in under six months through eliminated troubleshooting and prevented downtime in critical process control environments.

You’ll find the GE IC600PM507 powering the most heavily loaded racks in steel mills running caster segmentation, in large pumping stations with dozens of 32-point motor cards, and in automotive press lines where every slot is occupied and uptime is measured in seconds per year. It is the go-to upgrade whenever a facility performs a backplane refresh with an IC600KD510 or IC600KD542—the new backplane deserves a supply that can actually feed it properly.

IC600PM506 – 600 W intermediate version for lightly loaded 15-slot racks

IC600PM500 – Original 500 W supply (now the one you’re replacing)

IC600PM508 – 900 W high-capacity version for redundant-supply configurations

IC600BF830 – Power monitor module often added after PM507 upgrade

IC600KD542 – 15-slot backplane commonly refreshed at the same time

IC600CB515 – CPU rack extender when central rack also needs more power

IC600YR560 – Auxiliary cooling fan tray for racks pushed to 750 W continuous

IC600WD100 – Extended harness if remote-mounting the supply outside the rack

Before installing the GE IC600PM507, verify input voltage jumper position matches your plant standard (most U.S. sites are 120 VAC, European 240 VAC). Measure the existing 5 V rail under full load; if it’s already below 5.00 V, expect a few intelligent modules to re-initialize and possibly alarm on power-up—that’s normal and clears itself. Torque the four corner captive screws evenly to 12 in-lb and double-check that the remote-sense jumpers on the backplane (if present) are installed; without them the far-end slots can still see minor droop.

Post-install, leave the rack door open for the first hour and watch the front voltmeter settle at 5.15–5.20 V. Once a year, check the air filter (behind the front grille) and vacuum if the plant is dusty. The supply itself is designed to run for decades; the only routine replacement item is the internal fan, which GE still stocks separately. With those simple checks, the GE IC600PM507 will keep even the most heavily loaded Series Six rack happy indefinitely.
