120/240 VAC OR 125 VDC · 30 W · HIGH-CAPACITY 5 V RAIL
Emerson IC693PWR330H Series 90-30 High-Capacity Power Supply
A revision-H Series 90-30 supply designed to allocate the full 30 W capacity to the 5 V backplane rail when required.
Product Identification
IC693PWR330H is the revision-H high-capacity power supply for a Series 90-30 baseplate. It accepts a nominal 120/240 VAC or 125 VDC source and provides 5 V backplane power plus 24 V isolated and relay-power functions.
Unlike the standard PWR321, the PWR330 can allocate the full 30 W capacity to the 5 V rail. The sum of all output loads still cannot exceed 30 W, so baseplate power calculations must be retained with the rack record.
Engineering Data
Functions
Full 5 V allocation
Supports racks whose principal demand is on the logic rail while retaining the 30 W overall limit.
Dual source acceptance
The input stage accommodates approved AC or high-voltage DC control-power sources.
Integrated service functions
Power status, CPU serial access and battery connections remain at the rack supply position.
Series 90-30 form factor
Mounts in the dedicated leftmost position of the baseplate rather than an ordinary I/O slot.
About IndustryParts
https://www.industryparts.com/Exact identity before quotation
IndustryParts prepares IC693PWR330H enquiries around the complete manufacturer label, requested quantity and destination. For controlled replacements, include the host-system record, field photographs and configuration evidence that apply to this exact execution.
Applications
Logic-heavy Series 90-30 racks
Supplying configurations that require more 5 V power than the standard supply can provide.
AC-fed control cabinets
Operating from 120 or 240 VAC within the documented input range and grounding plan.
125 VDC plant systems
Using a suitable station DC source while maintaining polarity, protection and rack load records.
Lifecycle
Recalculate
List every baseplate module and calculate 5 V, isolated 24 V and relay loads before approval.
Isolate and wire
Verify the input source, grounding, terminal torque and protective devices with all hazardous voltage removed.
Observe and prove
Check supply indicators, CPU operation, battery status, serial access and stable rack behavior under load.
FAQ
Q01
Does “high capacity” make IC693PWR330H a 40 W supply?
+
No. Total output remains 30 W; the advantage is that the complete capacity can be allocated to the 5 V rail.
Q02
What rack evidence should accompany an IC693PWR330H enquiry?
+
Provide the H revision label, baseplate model, full module list, rail-load calculation, input-source details and battery arrangement.
Q03
Can IC693PWR330H occupy an ordinary Series 90-30 I/O slot?
+
No. It installs in the dedicated leftmost power-supply position of the baseplate.
Q04
Why must the input source be documented for IC693PWR330H?
+
The same supply can operate from approved AC or DC ranges, but field wiring, protection and grounding differ between those sources.
Q05
What indicates a successful IC693PWR330H replacement?
+
Correct power and system indicators, stable CPU startup, verified battery and serial functions, and a clean load calculation complete the record.
