SITOP PSU3400 DC/DC Power Supply 24 V / 5 A (6EP3133-0TA00-0AY0) CAN Electric — Industrial Automation Parts Supplier

A DC/DC converter for 24 V networks

Unlike AC-input SITOP supplies, the PSU3400 is fed from a DC network – a battery system, a train or ship DC busbar, or simply a distant 24 V source. It re-stabilizes that voltage, so the connected PLC, HMI or controller sees a clean 24 V regardless of line fluctuation, cable length or battery state of charge.

A wide tolerance window

The input accepts 14 to 32 V DC with startup from 18 V (derating required between 14 and 18 V). This window follows a discharging battery downward and absorbs cable voltage drop, while a mains buffering time of at least 5 ms rides through short input dips.

Adjustable output and clear diagnostics

The output voltage is set between 24 and 28 V with a potentiometer to compensate fixed line drop. A green LED signals 24 V OK and a yellow LED signals overload; short circuits are handled by electronic shutdown with automatic restart, and the output is protected against overvoltage (below 35 V).

Data per the Siemens catalogue entry and product documentation; confirm the current data sheet before mounting the module or sizing the 24 V load.

Galvanic isolation for clean DC segmentation

The input and output circuits are isolated, so a ground fault or disturbance on one DC segment does not propagate into the stabilized control voltage – the standard solution for ship and rail feeders.

Built for battery-backed networks

The 14-32 V window tracks a discharging battery far below the point where an AC-input supply would drop out, and the potentiometer trims the output up to 28 V to offset fixed cable losses.

Slim, parallel-capable, low-loss

At 32 mm housing width with zero side clearance it mounts densely on a 35 mm DIN rail; approx. 93% efficiency keeps cabinet heat low, and units can be paralleled for more power.

Pick the variant by input network (24 V or 48 V DC) and by output voltage/current; all seven share the same converter concept with adjustable output and galvanic isolation.

The converter is fed from a 24 V DC network – a battery system, a train or ship DC bus, or a remote 24 V source – and delivers a stabilized 24 V for PLCs, HMIs and controllers. Downstream load circuits can be distributed and monitored with SITOP PSE200U selectivity modules, backed up with SITOP DC-UPS modules and battery modules, or decoupled redundantly with SITOP PSE202U modules.

• Email sales@can-electric.com with the order number, quantity, delivery country, and whether the power module equips a new cabinet or replaces a failed unit.
• State the condition you need — new, new-surplus or refurbished is written on the quote, never implied.
• Prices are USD and ships go out from Hong Kong by DHL; availability is confirmed per order rather than taken from a catalogue status.
