The Siemens SITOP PSU6200 3-phase unit (6EP3433-7SB00-0AX0) is a 24 V DC / 5 A / 120 W power supply fed from a 3-phase line — input 400–500 V AC (323–576 V AC) or 450–600 V DC — with adjustable output 24–28 V, 91.2% efficiency, push-in terminals and a DC-OK signalling contact. It shares identical output ratings with its 1-phase sibling 6EP3333-7SB00-0AX0 but differs entirely on input phases and mains connection. New original, quoted per order, ships in 24h by DHL (3–7 days).

The SITOP PSU6200 6EP3433-7SB00-0AX0 brings the diagnostic-capable PSU6200 platform to 3-phase panels: a 400-500 V 3 AC wide-range input (450-600 V DC) feeds a stabilized, adjustable 24 V output in a 35 mm-wide metal housing. A green 24 V OK LED and an electronic DC OK contact (NO, 30 V DC/0.1 A) report supply status to the controller, while 150% extra power covers hard-starting loads.

The 6EP34xx 7SB00 family extends the all-around PSU6200 to 3-phase panels: the 5 A unit draws only 0.33 A per phase at 400 V, keeps 20 ms of mains buffering, and tolerates 323-576 V AC or 450-600 V DC – including unbalanced or DC-backed 3-phase networks.
The unit supplies 6 A continuously up to +45 C and 150% of rated current (7.5 A) for 5 s per minute. Output protection trips below 32 V on overvoltage, and on persistent short circuit the unit shuts down and periodically retries – the fault clears without a fuse or service call.
At 35 mm wide with 45 mm top/bottom clearance and push-in terminals on both sides, the metal housing snaps onto a 35 mm DIN rail; no side clearance is required, so cabinets stay compact at approx. 91.2% efficiency.

Data per the Siemens catalogue entry and product documentation; confirm the current data sheet before mounting the module or sizing the 24 V load.
Connecting directly to 400-500 V 3 AC saves a transformer or single-phase tap in new panels, and the wide 323-576 V range plus DC input option keeps one article number valid across plants and DC-backed systems.
150% for 5 s per minute and 6 A up to +45 C cover capacitive inputs, converters and actuators, so the 5 A unit serves panels that briefly exceed its rating without oversizing the cabinet.
The green 24 V OK LED and the electronic DC OK contact give the controller a hard signal, and the unit pairs with SITOP buffer, redundancy and DC-UPS modules when the application needs more availability.

Within the 3-phase line the PSU4200 is the basic alternative, the PSU6200 5 A is the only non-parallel unit, and all 10 A to 40 A ratings can be paralleled 2-up; the 7SC00 Ex variants add coated printed-circuit boards for corrosive atmospheres, while PSU8200/PSU8600 3-phase units cover modular and PROFINET-monitored systems.
The supply feeds 24 V control loads from a 400-500 V 3 AC or DC-backed network and pairs with SITOP selectivity, redundancy, buffer and DC-UPS modules. For parallel operation, remote On/Off or a switchable characteristic move up to the 3-phase SITOP PSU8200; for Web/PROFINET-integrated system supplies see SITOP PSU8600 (6EP3436/3437-8MB00).
It is the 5 A, 3-phase unit of the PSU6200 line, converting a 400-500 V 3 AC (or 450-600 V DC) input into a regulated, adjustable 24 V DC output for PLCs, HMIs, I/O and other control loads fed from a 3-phase panel.
Same PSU6200 platform and output, but the 6EP3433 connects to 400-500 V 3 AC (323-576 V) instead of 120/230 V 1 AC – for panels fed from a three-phase distribution, saving a single-phase tap.
150% of rated current (7.5 A) for 5 s per minute, plus 6 A continuous up to +45 C; above +60 C the load is derated by 3% per K.
No – only the green 24 V OK LED and the electronic DC OK contact (NO, 30 V DC/0.1 A). The diagnostics monitor with load/lifetime readout is on the 10 A, 20 A and 40 A 3-phase units; dealer listings claiming an interface on the 5 A unit should be corrected.
Not this 5 A unit. The 10 A, 20 A and 40 A 3-phase PSU6200 units can be paralleled 2-up, and the PSU8200 3-phase adds remote On/Off with switchable characteristic.
Yes, from 24 to 28 V with a front potentiometer, e.g. to offset cable losses; maximum continuous power is 120 W (144 W up to +45 C).
Yes – the 7SC00 variants (6EP3433-7SC00 for 5 A, 3434-7SC00 for 10 A, 3436-7SC00 for 20 A, 3437-7SC00 for 40 A) are the 3-phase PSU6200 Ex units with coated printed-circuit boards for corrosive atmospheres.
323 to 576 V 3 AC (rated 400-500 V) or 450 to 600 V DC, 47-63 Hz – including unbalanced networks and DC-backed 3-phase systems; this standard unit carries no ATEX/IECEx approval.
CE, cULus (UL 508 / CSA C22.2 No. 107.1), UKCA, EAC, RCM, SEMI F47, CB and BIS; for shipbuilding the unit is ABS and DNV approved.
