Technical FAQs

1. What is the primary function of the Siemens 6AG2333-0SB00-4AY0?

The 6AG2333-0SB00-4AY0 is a SIPLUS PS PSU2600 TX RAIL stabilized power supply that converts a nominal 110 V DC railway supply into regulated 24 V DC power for automation and control equipment.

2. What input voltage range does the power supply support?

The power supply has a nominal 110 V DC input and supports an input range of 77 to 154 V DC, providing tolerance for variations in the vehicle or infrastructure battery supply.

3. What output voltage and current are available?

The rated output is 24 V DC at 5 A. The output voltage can be adjusted from 24 to 28.8 V DC, with a maximum output power of 120 W.

4. Is the output electrically isolated from the input?

Yes. The input and output are galvanically isolated, providing electrical separation between the railway DC source and the connected 24 V control circuit.

5. How is the output voltage adjusted?

The output voltage is adjusted using the integrated potentiometer. The adjustment range is 24 to 28.8 V DC, allowing compensation for voltage drops in longer supply cables or specific load requirements.

6. Does the 6AG2333-0SB00-4AY0 provide power-failure buffering?

Yes. At rated output current, the unit provides a minimum mains buffering time of approximately 20 ms under the specified input conditions, helping bridge short interruptions in the DC supply.

7. What protection functions are provided on the output?

The output is short-circuit proof and incorporates current limitation. The power supply also provides overvoltage protection, with the output protected against excessive voltage conditions.

8. How can the 24 V output status be monitored externally?

A green LED provides local indication of 24 V OK status. In addition, a normally open relay contact rated at up to 60 V DC and 0.3 A can be used to transmit the 24 V OK condition to an external monitoring or control circuit.

9. What environmental protection does the SIPLUS version provide?

The module uses conformal coating to improve resistance against demanding environmental influences. It is designed for railway applications and supports operation from -40 to +70 °C, with +85 °C permitted for 10 minutes under the applicable railway temperature classes.

10. How is the 6AG2333-0SB00-4AY0 installed?

The power supply is designed for DIN rail installation and snaps onto a standard EN 60715 35 × 7.5/15 top-hat rail. Electrical connections are made using screw terminals.
