Emerson IC694PWR330A 30 W AC/DC Power Supply, Revision A
A revision-A identity in the IC694PWR330 30 W serial-expansion backplane power-supply family.
Product Profile
Emerson IC694PWR330A identifies an A-revision unit in the IC694PWR330 power-supply family for PACSystems RX3i IC694 serial expansion backplanes.
The manufacturer publishes an 85–264 VAC or 100–300 VDC input range, 30 W total load capacity and one-slot backplane occupancy for the base IC694PWR330 design.
The final A is retained as part of the submitted label. Suitability is approved against the installed supply label, expansion-rack load calculation and applicable revision documentation.
Engineering Data
System Architecture
Dual-source input family
The published design accepts the documented AC or DC input ranges.
Defined rack budget
Thirty watts is the total available load and must be checked against the complete expansion rack.
Visible operating state
Power, OK and Run indicators support maintenance diagnostics.
Revision-aware receipt
The A suffix, terminal arrangement and rack context are checked before installation.
Compatibility & Service
Calculate before removal
List every installed module and compare the full backplane demand with the 30 W capacity of IC694PWR330A.
Control the source
Confirm input type, branch protection, protective earth, terminal torque and power isolation.
Restore by evidence
Reconnect by the recorded terminal map and verify Power, OK and Run indications plus normal rack diagnostics.
Applications
Serial expansion rack power
Supplying a documented IC694-series expansion backplane within the published load limit.
Controlled power-supply exchange
Replacing an A-revision unit after input, rack and conductor evidence is captured.
Rack-load remediation
Recalculating the complete module load when diagnostics or expansion changes indicate insufficient margin.

FAQ
Does IC694PWR330A support redundant load sharing?
No. Emerson states that load sharing and redundancy are not supported for the IC694PWR330 design.
What must be calculated before ordering IC694PWR330A?
Calculate the complete IC694 expansion-backplane load, including every installed module, rather than relying on the previous supply alone.
Can IC694PWR330A be selected only from the 120/240 VAC description?
No. Confirm the actual source, allowable range, branch protection, conductor condition, rack type and revision label.
What does the A ending mean for a IC694PWR330A enquiry?
It is part of the submitted hardware identity and should remain in the purchasing and receiving record until revision compatibility is documented.
What proves IC694PWR330A is ready after installation?
Confirm stable input voltage, correct LEDs, normal expansion-rack diagnostics and successful I/O checks under representative load.
