Description
HIMA K9203A 996920360 | 19-Inch Rack Fan
Product Introduction
In a HIMA control cabinet, rack ventilation is part of the operating environment—not an optional convenience. The HIMA K9203A (996920360) is an OEM-documented circulation fan designed to provide forced ventilation in 19-inch rack installations. Its three axial fans align with HIMA 19-inch subracks to move air through the installed equipment.
HIMA’s K9203A datasheet specifies 24 VDC operation, a maximum current of 750 mA, 300 m³/h airflow, and a 1 RU rack footprint. The unit also includes redundant supply, fan-operation monitoring, and voltage monitoring. These features make it a configuration-specific cooling accessory for legacy HIMA installations, rather than a generic fan or safety logic module.
For replacement procurement, verify the complete model and order number, mounting dimensions, connector, and cabinet requirements. A similar-looking fan assembly is not proof of electrical or mechanical interchangeability.

Global Sourcing & Live-Test SOP
For a surplus HIMA K9203A, inspection should establish both fan functionality and the condition of its monitoring and supply interfaces.
1. Inbound Verification
- Photograph the complete nameplate and confirm / 996920360.
- Inspect the rack frame, mounting ears, and fasteners.
- Check all three axial fans for damaged blades, debris, or bearing wear.
- Inspect connectors and terminals for corrosion, bent contacts, or repair marks.
- Compare dimensions and mounting arrangement with the installed unit.
- Record serial number and revision markings where available.
- Retain supplier condition statements and available traceability documents.
2. Controlled Power-Up
- Confirm the 24 VDC supply and connector pinout against the OEM documentation.
- Use a current-limited supply with monitoring.
- Verify that all three fans start and remain operational.
- Check for abnormal noise, vibration, or intermittent startup.
- Measure current draw and compare it with the applicable rating.
- Check the power and fan-status indicators, where fitted.
3. Monitoring and Airflow Verification
- Confirm airflow direction against the rack’s cooling design.
- Verify consistent operation across all three fans.
- Check the fan-operation monitoring function using the approved test procedure.
- Verify voltage-monitoring behavior where the test setup supports it.
- Confirm that the assembly fits the intended 19-inch rack position.
- Do not bypass cabinet cooling alarms or safety-system diagnostics.
4. Extended Heat Run
For a unit advertised as tested, conduct an extended powered run under controlled conditions.
Monitor:
- Fan startup and rotation consistency
- Current stability
- Abnormal noise or vibration
- Connector and wiring temperature
- Airflow consistency
- Unexpected fan stoppages
- Monitoring indications
Record test duration, applied voltage, measured current, and observed condition. Do not claim a 24-hour test unless it was actually performed and documented.
5. Final Preparation
- Record the exact model and order number.
- Photograph the complete fan assembly and connectors.
- Document whether all three fans were tested.
- Include available test results and condition details.
- Protect fan blades, rack ears, and connectors during shipment.
- Use suitable ESD-aware packaging where monitoring electronics are present.
- Clearly state whether the unit is new, used, refurbished, or tested surplus.
Field Engineer’s Pitfall Guide
❗ Do not confuse the rack fan with a relay or controller module
Some reseller pages assign unrelated functions to . HIMA’s datasheet identifies it as a three-axial-fan rack circulation unit. Verify the actual nameplate and OEM documentation before using a marketplace category to determine application.
❗ Confirm the complete order number
The requested 996920360 should be matched against the nameplate and supplier photos. Do not assume that K9203, , K9202B, or another similar designation represents an interchangeable assembly.
❗ Do not overlook fan monitoring and redundant supply
The is documented with redundant supply and fan-operation monitoring. A replacement that only provides airflow—but does not match the installed electrical or monitoring arrangement—may not satisfy the original cabinet requirements. Verify the complete installation configuration before returning the rack to service.
Intent-Driven FAQ
What is the HIMA 996920360?
It is a HIMA rack-mounted circulation fan designed for forced ventilation in 19-inch rack installations. The OEM datasheet specifies three axial fans.
Is the HIMA a safety relay or PLC module?
No. The HIMA datasheet identifies it as a rack fan, not a safety logic or signal-processing module.
What voltage does the require?
The datasheet specifies 24 VDC operation, with a voltage tolerance of -15% to +20% and a maximum current of 750 mA. Verify the unit and wiring before applying power.
How many fans are included?
The OEM datasheet describes three axial fans in the circulation unit. For surplus purchases, confirm that all three are physically present and operational.
What is the airflow rating of the ?
HIMA’s datasheet specifies 300 m³/h. Actual cooling performance in service also depends on installation, airflow restrictions, and cabinet configuration.
Can the be hot-swapped?
Do not assume hot-swap capability. Treat replacement as a power-off maintenance operation unless the applicable HIMA system documentation explicitly authorizes live replacement.
What should be checked before buying a used ?
Confirm the full model and order number, three-fan configuration, 24 VDC rating, connector, mounting dimensions, fan-monitoring condition, and supplier test status. Request clear nameplate and assembly photos before purchase.
Bottom Line for Buyers
The HIMA 996920360 is an OEM-documented three-axial-fan rack circulation unit for 19-inch installations. Its published ratings include 24 VDC operation, 300 m³/h airflow, a maximum current of 750 mA, and a 1 RU footprint.
For replacement procurement, match the exact order number and confirm the fan assembly, connector, monitoring interface, and mounting arrangement. Request documented test results before treating a surplus unit as service-ready.
