Product Description

The SIEMENS 6EP3334-8SB00-0AY0 is a SITOP PSU8200 stabilized power supply for industrial control cabinets. It converts a single-phase 120/230 V AC supply into regulated 24 V DC at up to 10 A for PLCs, I/O, sensors, communication modules and other control loads.

Automatic input-range selection, 94% efficiency, a 35 ms minimum mains buffering time and adjustable 24 to 28.8 V output support stable DC distribution. The unit also provides a relay contact for the “24 V OK” status and selectable overload behaviour.

Use this model where a 240 W DIN-rail supply fits the load calculation, fault-current strategy and enclosure thermal design. Confirm branch protection, conductor size, grounding, derating above 60 °C and available mounting clearance before commissioning.

Product Features & Functions

Regulated 24 V DC outputSupplies 10 A nominal current and 240 W typical active output power. Overload managementSupports short-circuit protection, selectable constant-current or latching shutdown behaviour and short-duration overload capability. Status and system integrationProvides front-panel operating indication and a relay contact for the 24 V OK signal.

Technical Notes

Electrical safety: Disconnect and verify the AC input is de-energized before wiring or service. Connect protective earth and use the conductor sizes, branch protection and terminal torque specified in the Siemens equipment manual.

Thermal installation: Output current is derated by 2% per kelvin from +60 to +70 °C. Mount on a TH35 DIN rail with the specified installation clearances and maintain cabinet airflow.

FAQ

Is 6EP3334-8SB00-0AY0 suitable for a 10 A continuous load?Yes within the published operating conditions. Recheck cabinet temperature, input voltage, output-voltage setting, cable losses and derating, especially above +60 °C.
Can the output voltage be adjusted?Yes. The output is adjustable from 24 to 28.8 V DC. Set it with a calibrated meter and confirm that every connected load permits the selected voltage.
What does the 24 V OK interface provide?The unit provides a normally open relay contact rated 60 V DC / 0.3 A for the 24 V OK status. Use it as a monitoring signal, not as a load supply.
How does the power supply respond to short circuit or overload?Siemens specifies short-circuit protection with selectable constant-current or latching shutdown behaviour, plus temporary overload capability. Configure the response to match the machine recovery strategy.
What must be checked when replacing another SITOP supply?Compare article number, input range, output current, mounting width, terminal arrangement, status wiring, overload setting and cabinet clearance. Do not substitute only by matching 24 V and 10 A.
What should be inspected when the unit arrives?Confirm the full article number, country-of-origin label, housing and terminals, adjustment control and status indicators. Verify the agreed accessory and documentation scope before installation.
