Series Three High-Capacity Rack Power
GE Fanuc IC630PWR310 / IC630PWR314 Series Three Power Supplies
High-capacity Series Three rack supplies with either 115/230 Vac or 24 Vdc input.
IC630PWR310High-capacity local rack power supply
IC630PWR314High-capacity local rack power supply
Product Description
IC630PWR310 and IC630PWR314 are high-capacity GE Fanuc Series Three power supplies for a local CPU or I/O base. They provide the same listed backplane load capacity but accept different plant sources: IC630PWR310 is the 115/230 Vac version, while IC630PWR314 is the 24 Vdc version.
Each supply provides 300 units of +5 V load and 200 units of +12 V load, with one Series Three load unit defined as 10 mA. The installed I/O and communication hardware must be totaled by rail; a base with open slots can still exceed a power rail when higher-load modules are fitted.
The replacement record must include input source, complete alpha revision, base-unit size, wiring, grounding and every installed module. Where a Data Communications Module shares rack power, its additional load and the manual's external-supply guidance must be considered before commissioning.

Power Capacity and Load Planning
Both supplies increase the available Series Three backplane capacity to 300 +5 V load units and 200 +12 V load units.
The difference is on the input side: IC630PWR310 belongs on a 115/230 Vac source; IC630PWR314 belongs on a 24 Vdc source.
Convert each module requirement into the Series Three load-unit basis and total the rails independently before approving the rack configuration.
Include the DCM and other communication accessories in the calculation; their presence can change whether an external supply is needed.
Installation and Acceptance
Match the source
Set and wire IC630PWR310 for the documented ac source, or observe correct dc polarity and protection for IC630PWR314.
Confirm capacity
Compare the complete module inventory with the +5 V and +12 V load-unit limits.
Restore operation
Energize the rack, confirm stable logic power and CPU status, then validate communication and I/O modules one section at a time.
Product FAQ
What is the main difference between IC630PWR310 and IC630PWR314?
They provide the same listed high-capacity backplane load units, but IC630PWR310 uses 115/230 Vac and IC630PWR314 uses 24 Vdc.
How much +5 V capacity do IC630PWR310 and IC630PWR314 provide?
Each provides 300 Series Three load units at +5 V, with one unit defined as 10 mA.
Why must the +12 V load be calculated for IC630PWR310 or IC630PWR314?
Communication and certain I/O devices draw from +12 V independently of the +5 V rail; the documented limit is 200 load units.
Can IC630PWR310 and IC630PWR314 be swapped without rewiring?
No. Their input sources are different, so source selection, terminals, protection and polarity requirements must match the exact supply.
What should be checked when a DCM is used with IC630PWR310 or IC630PWR314?
Include the DCM in the rail calculation and follow the manual's internal/external power selection guidance for the complete rack load.
