Description
Application Scenarios
A German automotive body-shop integrator was retrofitting a weld-cell cabinet that fed an S7-1515F PLC, two ET 200SP remote racks, eight servo-axis 24 V brake circuits, and a vision-pick light curtain — total steady load ~16 A at 24 V. The problem: every Monday morning “cold start,” the brake coils + retract solenoids inrush pushed the old 15 A Mean Well clone into hiccup mode, tripping the cell and costing ~€800 per spurious stop. The integrator swapped in the 6EP1336-3BA10. Its Extra-Power function (1.5×Irated, 30 A for 5 s) absorbed the brake-inrush without blinking, and the 25 ms Power Boost (3×, 60 A) covered the worst-case short-duration spike when all eight axes homed simultaneously. Even better, the cabinet had a small 110 V DC battery float sitting on the site’s UPS bus — the 6EP1336-3BA10 is the only PSU8200 20 A that digest both AC and DC input, so the same unit seamlessly rode through a 40 ms AC dropout by pulling from the DC side. Six months in, zero nuisance trips. The key pain point solved: “Monday-morning surge + mixed AC/DC utility” — a combo most 20 A supplies punt on.

Technical Principles and Innovative Values
- Innovation Point 1: AC/DC Universal Input in the 20 A Class. Most 480 W DIN-rail supplies lock you to AC only. The 6EP1336-3BA10 takes single-phase AC, two-phase AC, or 110–220 V DC on the same terminals. This matters for sites with DC battery backup, solar-assisted MCC sections, or marine 120 V DC house buses — one spare part covers three utility topologies.
- Innovation Point 2: Two-Tier Overload Architecture (Power Boost + Extra-Power). The 6EP1336-3BA10 doesn’t just “current-limit.” It runs a 60 A / 25 ms Power Boost (covers transformer magnetizing inrush, contactor coil pile-ups), then drops to 30 A constant-current Extra-Power for 5 s (covers motor-brake homing, capacitor pre-charge). Most competitors give you one or the other; having both graded avoids nuisance tripping and protects the downstream wiring.
- Innovation Point 3: A/B Parallel Soft-Share Switch. Dial A = normal; dial B = softened voltage droop curve so two paralleled 6EP1336-3BA10 units share load within a few percent instead of one hogging. No external diode module required for up-to-2-unit parallel — the droop does the work. For a 20 A unit this is unusually sophisticated; 10 A class PSU8200 siblings don’t get it.
Application Cases and Industry Value
Case 1 – High-Speed Bottling Line (Belgium, FMCG): A filler/capper monoblock ran S7-1512SP + 14 ET 200AL slices + 24 V valve island bank, steady ~15 A. Every tool-change the operator ramped all 40 filling needles simultaneously, spiking to ~26 A for ~3 s — the previous 15 A supply tripped its electronic fuse twice a week. The plant engineer dropped in a 6EP1336-3BA10; Extra-Power carried the 3 s surge at 30 A, no trip. The “24 V OK” NO contact (13/14) was wired into the S7’s diagnostic FB so maintenance got a push-notification the moment output dipped below 20 V. Twelve-month uptime report: zero supply-related stops. The 6EP1336-3BA10 also shaved ~18 W losses vs. the old unit (94 % vs. ~89 %), which the site ESG report counted toward their “cabinet efficiency” KPI.Case 2 – Offshore Support Vessel E-house (North Sea): The vessel’s 120 V DC house battery floats the utility; when generators kick in, the bus flips AC. The integrator specced the 6EP1336-3BA10 precisely because it tolerates both — no transfer switch needed on the 24 V backbone that feeds the DP (dynamic positioning) I/O rack and the crane-safe PLC. The A/B selector was set to B (parallel-ready) even though only one unit ran, future-proofing for a redundancy module later. Chief electrician note: “The 6EP1336-3BA10 didn’t blink when we switched bus source mid-watch. That’s the unit I want on the spares list.”
