Siemens 6EP1434-2BA20 SITOP PSU300S 24 V DC 10 A Power Supply

6EP1434-2BA20 is a Siemens SITOP PSU300S stabilized three-phase power supply that converts a 400-500 V 3 AC source into regulated 24 V DC at 10 A for compatible industrial control, instrumentation and automation loads.

6EP1434-2BA20 is configured for a three-phase 400-500 V AC nominal supply, with a published 340-550 V operating range. It should not be treated as a single-phase power supply; the incoming phases, protective earth and upstream protection must match Siemens installation requirements.

6EP1434-2BA20 provides a regulated 24 V DC output rated at 10 A and 240 W. Siemens documents 150% overload capability for up to five seconds per minute, while continuous loading and temperature derating must remain within the official technical data.

6EP1434-2BA20 is identified by Siemens as the successor product for 6EP1434-2BA10. Before replacement, confirm the complete article number, input wiring, dimensions, terminal arrangement, approvals and cabinet conditions rather than assuming a drop-in substitution.

6EP1434-2BA20 supports parallel connection of two units for increased power according to Siemens technical data. Both units must have compatible output settings, wiring, protection, thermal conditions and load-sharing arrangements before they are commissioned together.

6EP1434-2BA20 requires a suitable three-phase supply, protective earth, IP20 cabinet protection, correct DIN-rail mounting and adequate ventilation. Its -25 to +70 °C operating range includes output-current derating at elevated temperature, so enclosure temperature and clearance must be verified.

6EP1434-2BA20 should be quoted with the complete order number, quantity, destination, three-phase mains voltage, total 24 V DC load, cabinet temperature, mounting space and any required approvals so compatibility and availability can be checked independently.
