PRODUCT DESCRIPTION
Regulated 24 V power for industrial control systems
Siemens 6EP3333-7SB00-0AX0 is a SITOP PSU6200 power supply that converts a compatible single-phase AC or DC source into regulated 24 V DC. Its 5 A rated output supplies industrial control loads, while the front potentiometer permits output-voltage adjustment within the documented range.
The unit uses spring-loaded terminals and provides a signaling contact for output-status monitoring. Install it vertically in an appropriate enclosure, maintain the specified ventilation clearances, and check load starting current, protective measures and temperature derating before selecting it for a machine or control cabinet.

ACTUAL APPLICATIONS
24 V supply arrangements for industrial automation
These uses follow the applicable SITOP PSU6200 manual. They describe engineered power-supply arrangements, not claims that this exact order code was installed in a named customer project. Optional protection and UPS modules are separate components.
-
01 · CONTROL CABINET POWER
Supplying machine control circuits
In an automated machine cabinet, this power supply converts the incoming AC or DC source into a regulated 24 V rail for compatible control loads. The selected load total and starting profile must remain within the 5 A rating and documented overload and derating limits. -
02 · SELECTIVE LOAD DISTRIBUTION
Powering separately protected load branches
In a 24 V distribution system using an appropriately selected SITOP selectivity module, the PSU6200 provides the upstream DC supply. The separate selectivity module monitors and disconnects an overloaded branch so that a branch fault need not collapse every connected control load. -
03 · BUFFERED AUTOMATION POWER
Supporting controlled shutdown during outages
In PC-based automation with a correctly sized SITOP DC-UPS, the PSU6200 feeds the normal 24 V supply path. The separate UPS and energy-storage equipment provide outage buffering so the control application can preserve process data and perform a controlled shutdown.

Manuals & support
SITOP PSU6200 / INDUSTRIAL DC POWER
Integrate a regulated supply into the 24 V power architecture
Connect the PSU6200 to a compatible AC or DC source and distribute its output through appropriately rated conductors and protective devices. The power supply provides the DC rail; it does not replace the control system, branch protection or machine safety circuits.
Use the exact-model terminal data for line, protective-earth, output and signaling connections. The output status contact can report supply condition to a monitoring circuit within its contact rating, without being treated as a safety-rated shutdown device.
Engineering must account for sustained load, startup demand, adjusted output voltage and enclosure temperature. Where longer outage support or selective load isolation is required, select separate documented SITOP modules and verify the complete power architecture.
Features:
- Exact article: 6EP3333-7SB00-0AX0
- Check AC or DC input and protective measures
- Confirm enclosure clearances and temperature derating
The Siemens 6EP3333-7SB00-0AX0 24 V / 5 A regulated power supply requires power source, load current, protective measures and thermal derating to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Match the 6EP3333-7SB00-0AX0 article and 24 V/5 A version before replacement. Other PSU6200 variants differ in output capacity, diagnostic features and parallel-operation capability; the family name alone does not establish interchangeability.
Isolate the incoming supply and prevent reconnection before handling the unit. Preserve protective-earth continuity, record the output-voltage setting and inspect load wiring and branch protection before fitting the replacement.
The live Siemens overview observed for this draft identifies an active product. That catalog status does not confirm an individual stock unit or a future successor; verify the quoted identity and the installed system requirements.
Features:
- Match the complete 6EP3333-7SB00-0AX0 article
- Match the complete 6EP3333-7SB00-0AX0 order code
- Size the supply for running and starting loads
The Siemens 6EP3333-7SB00-0AX0 24 V / 5 A regulated power supply requires replacement verification against power source, load current, protective measures and thermal derating before commissioning.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6EP3333-7SB00-0AX0
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Can this power supply operate from a DC input?
Yes. Siemens lists a rated 120-240 V DC input as well as a 120-240 V AC input. For DC operation, connect positive to L1 and negative to N and follow the documented protective-conductor and input-protection requirements. -
Can I raise the output above 24 V?
The front potentiometer allows adjustment from 24 to 28 V. Siemens requires output-current derating of 4% per volt above the nominal 24 V, or the specified temperature allowance; verify the load voltage limit before adjustment. -
How much space is needed above and below the unit?
The standard vertical mounting arrangement requires at least 45 mm above and below the unit, with a maximum cable-duct depth of 50 mm. Input terminals face down and output terminals face up; lateral clearance is not required in that arrangement. -
What happens if an output short circuit occurs?
The supply uses electronic protection and automatic hiccup restart. Output cabling and branch protection must still be sized correctly; this feature does not replace the protective measures required for the complete installation. -
Does the 5 A version include the diagnostic monitor found on larger units?
The exact-model table lists a green 24 V OK LED and a relay signaling contact. Do not assume that the diagnostic monitor shown for other PSU6200 variants is fitted to this 5 A order code. -
Can two of these units be paralleled to increase current?
Do not assume so from the series application chapter. The exact 24 V/5 A column explicitly marks parallel connection for increased power as not supported. Select a documented architecture and suitable devices if additional current or redundancy is required. -
Does it supply 5 A throughout the entire operating temperature range?
No. The -25 to +70 C operating range is subject to derating. The exact-model table specifies 3% of rated current per kelvin from 60 to 70 C; mounting position, altitude and increased output voltage can impose further limits. -
Is an external UPS necessary for longer power failures?
The supply has limited internal mains buffering, not sustained battery backup. Siemens describes separate SITOP buffer and DC-UPS modules for longer interruptions. Select the UPS and energy storage for the connected load and required shutdown or ride-through time.
