A one-slot 30 W supply for IC694-series serial expansion backplanes, accepting AC or DC input.
Module Profile
Emerson / GE Fanuc IC693PWR330 is a PACSystems RX3i Serial Expansion Backplane 30 W Power Supply identified by the complete submitted catalog string. The suffix and revision characters remain part of the supply identity.
Selection of IC693PWR330 should follow the installed label, rack or controller record, field wiring and the verified technical details below; a neighboring family number is not treated as interchangeable.
Published Data
System Role
The supply powers an IC694-series serial expansion backplane from a wide-range AC or DC source.
Its total published load capacity is 30 W across all backplane loads.
Front indicators separate incoming power, supply health and run status.
The module does not provide load sharing or redundant-parallel operation.
Integration Checks
- Calculate the complete expansion-rack load before shutdown; do not copy the old supply rating alone.
- Isolate and verify the input source, branch protection, earth and conductor condition.
- Confirm the power supply occupies the documented rack position and that no redundancy scheme is assumed.
- After energizing, verify all three indicators, backplane voltages, module diagnostics and rack communication.
Use Cases
- Powering PACSystems RX3i IC694-series serial expansion racks.
- Replacement where the calculated backplane load remains within 30 W.
- Installations using documented 120/240 VAC or 125 VDC nominal sources.
FAQ
Q01Can IC693PWR330 share load with a second power supply?+
No. The official specification states that load sharing and redundancy are not supported.
Q02What input range can IC693PWR330 accept?+
The published ranges are 85 to 264 VAC or 100 to 300 VDC, with 120/240 VAC or 125 VDC nominal input.
Q03How is the 30 W IC693PWR330 rating applied?+
It is the total capacity for all backplane loads, so calculate the complete expansion-rack demand before replacement.
Q04What wiring should accompany an IC693PWR330 enquiry?+
Provide input-source details, protection, earth arrangement, conductor size, terminal photographs and the complete rack load list.
Q05Which checks confirm IC693PWR330 operation?+
Verify Power, OK and Run indicators, stable backplane operation, rack communications and the absence of supply diagnostics under full load.
