The Siemens 6EP3336-7SB00-3AX0 is a SITOP stabilized power supply, 24 V DC / 20 A, input 120-240 V AC.
A stable 24 V supply is one of the first things to check when a machine shows random faults or resets; replacing an aged supply often cures intermittent problems.

What to check first
- Note the firmware version printed on the old unit; TIA Portal or LOGO! Soft Comfort must support it.
- Look for signs of overvoltage, water or heat damage in the cabinet so the new part does not fail for the same reason.
- Compare the full order number 6EP3336-7SB00-3AX0 with the label on the old unit, including the last digits (they identify the version).
