The Siemens 6EP3436-8SB00-0AY0 is a SITOP PSU8200 power supply (SITOP modular line) that converts 400-500 V 3 AC into a stabilized, isolated 24 V DC output rated 20 A, typically 480 W of output power. Per the Siemens data sheet it has an input range set as described in the table below, an output adjustable from 24 … 28 V; max. 480 W and an efficiency of 94 %.
SITOP units are the standard Siemens 24 V DC supplies in control panels. They feed PLCs, HMI panels, sensors, solenoid valves, relays and contactor coils, and a stable 24 V supply is one of the first things to check when a machine shows random faults or resets.

Typical applications
- 24 V DC supply for PLCs, remote I/O and HMI panels
- Sensors, solenoid valves, relays and contactor coils in machine panels
- Replacement of a failed or overheated 24 V supply of the same rating
- Packaging, food, textile and plastic machinery control cabinets
Compatibility and replacement
Check the rated current of the old unit and the total 24 V load before ordering. If your panel draws more than 20 A, choose the next size up. Siemens offers several SITOP lines (smart, modular, PSU100S, PSU200M, PSU8200); if your old supply is a different line, send us its order number and we will confirm the closest current match.
