SIEMENS 6EP1333-1AL12 SITOP Power 5 A

Buy online your SIEMENS 6EP1333-1AL12 SITOP Power 5 A from UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

This SIEMENS SITOP 6EP1333-1AL12 is a regulated 24 V DC / 5 A industrial power supply designed to provide stable power to CNC controllers, PLCs, I/O modules, HMIs, sensors and relay circuits in industrial control cabinets.

The SITOP power supply is designed for DIN-rail installation and provides a regulated 24 V DC output with integrated overload and short-circuit protection. Its compact design and screw terminals allow straightforward installation and quick replacement during maintenance operations.

The 6EP1333-1AL12 is suitable for SIMATIC, SINUMERIK and SINAMICS control cabinets where a reliable 24 V DC supply is required for control logic, I/O and auxiliary circuits. It can be used as a replacement unit, spare part or CNC replacement component for machine tools, automation systems and retrofit projects.

This model provides a 24 V DC output rated at 5 A and is designed for single-phase AC industrial power networks. The output voltage can be adjusted to compensate for voltage drops in longer control circuits, helping maintain stable voltage at connected devices.

This SIEMENS SITOP power supply is commonly kept as a stocked spare or emergency spare because a failed 24 V supply can stop an entire CNC or automation system. Keeping a replacement available helps maintenance teams restore the control cabinet quickly and reduce unplanned machine downtime.

Each unit can be function-tested by skilled engineers on appropriate electrical or CNC test equipment to verify output regulation and operation under load. Protective packaging is used for industrial shipping, and a commercial warranty is provided according to our standard terms.

Cnc-shopping can supply the SIEMENS 6EP1333-1AL12 as a tested unit, spare part or refurbished unit, depending on availability. We can also assist with sourcing obsolete parts, repair service and exchange service, with worldwide shipping and fast dispatch depending on stock.

Frequently asked questions about 6EP1333-1AL12:

What mains supply does this unit accept?
It is a single-phase AC input power supply suitable for 120 V or 230 V 50/60 Hz networks depending on configuration. This fits most industrial panels in North America and Europe without redesign.

Is the output adjustable for voltage drop compensation?
Yes, the 24 V DC output can be trimmed within a narrow range to offset wiring losses on longer control runs. This helps maintain stable voltage at PLC and I/O terminals.

Where is it typically installed in a CNC machine?
It mounts on DIN rail inside the control cabinet, feeding the 24 V bus for the CNC controller, PLC, safety relays, sensors and HMI. The compact housing simplifies panel layouts and field replacement.

Is it compatible with SIMATIC and SINUMERIK systems?
It is widely used to supply the 24 V DC control circuits commonly found in SIMATIC PLC racks and SINUMERIK CNC cabinets. Always verify current rating and wiring against your machine documentation before replacement.

Can this be used as a direct replacement for the same code?
Yes, it is intended as a drop-in replacement for the identical reference. Match input selection and output setting to the existing unit during the swap and keep the same wiring scheme.
