Description
Siemens SITOP Power 5 Power Supply
PLC Power Supply — 24VDC / 5A (Model: 6EP1333-1SL11)
This Siemens SITOP power supply is in excellent, fully tested used condition. Pulled from a working control cabinet, the unit has been cleaned and load-tested to ensure stable 24VDC voltage output at a full 5A current load. All wire clamping terminals and the manual voltage input selector slide switch are in perfect working order.
Product Overview
The Siemens SITOP Power 5 (6EP1333-1SL11) is a highly efficient, regulated industrial power supply designed to provide stable DC power to PLCs, sensors, actuators, and other critical automation hardware. Engineered specifically for demanding industrial switchgear, it delivers stable performance even under heavy loads and fluctuating mains voltages.
This unit is classified as E-Stand 5 (Product Version 5) and features a manually switchable input voltage range, allowing it to easily adapt to standard single-phase mains globally. With integrated overcurrent and short-circuit protection safeguards, it isolates downstream control loops to prevent costly equipment failures.
