That 60 A peak covers the inrush when a downstream load starts — think a bank of contactors pulling in or a drive DC bus charging — without tripping the output. ## Panel fit and approvals Snaps onto DIN rail EN 60715 35x7.5/15 — standard 35 mm rail. The enclosure is 50 mm wide, 139 mm high, 125 mm deep. That 50 mm width is the same as a typical single-pole MCB; it slots into a crowded panel without re-laying out the rail. IP20 protection class means it's for a clean, dry enclosure — not for washdown zones. Carries cULus listing to UL 508 and CSA C22.2 No. 107.1 (File E197259), plus CE, EAC, and shipbuilding approvals from ABS and DNV GL. That marine stamp means it's accepted for engine-room and deck auxiliary panels where classification society sign-off is required. No ATEX approval — it's not rated for explosive atmospheres. ## How it buffers and what the LEDs tell you In normal operation the LED is green (OK) and the floating changeover contact signals that the input supply voltage is above the cut-in threshold. When the input drops, it switches to buffered mode: the yellow LED (Bat) lights, and the contact shifts to \"Bat\". If the battery voltage falls below 20.4 V DC, the red LED (alarm) comes on and the alarm contact toggles. When the energy storage is above 85%, the green LED (Bat > 85%) is on and the NO contact closes. The output voltage follows Vin minus about 0.2 V in normal operation, so you're not losing much headroom. The input voltage range is 21 to 29 V DC — it works with a 24 V nominal bus that sags under load or rises during charging. The charging current is selectable between 0.1 A and 4 A, matching the battery module size and recharge time you need. ## Sourcing and compatibility The 6EP4136-3AB00-0AY0 is specified with battery-type energy storage — it connects to an external battery module (listed as an electrical accessory). The interface design is \"without\", meaning no integrated communication module; signalling is through the floating contacts. For a replacement of an existing SITOP UPS in a 24 V DC buffer application, this module fits the same DIN footprint and wiring scheme — confirm the battery module model and the load current stays under 20 A continuous.","metaTitle":"Siemens 6EP4136-3AB00-0AY0 SITOP UPS1600, 20 A","metaDescription":"Siemens SITOP UPS1600 DC UPS module, 20 A rated, 60 A peak.
