Product Overview
The Siemens 6EP1336-1LB00 SITOP PSU100L is a stabilized industrial power supply designed for demanding automation environments. With a 24 V DC / 20 A output and wide-range AC/DC input (100-240 V AC or 100-240 V DC), this module delivers consistent, isolated power to critical control systems. Its 92% efficiency reduces energy costs, while the adjustable output voltage (22.8–26.4 V) and comprehensive protection features ensure reliable operation even under load fluctuations or short circuits.

The Siemens 6EP1336-1LB00 uses a potentiometer for easy output voltage setting and offers a green LED for 24 V OK indication. Its short-circuit protection follows a constant current characteristic, with an enduring short-circuit current of 24 A typical.
Industry Applications
This power supply is ideal for control cabinets in manufacturing, process automation, and machine building. For example, in a 24 V DC sensor/actuator network, the Siemens 6EP1336-1LB00 ensures stable voltage even during line brownouts, thanks to its 20 ms buffering. Its wide temperature range (-25 °C to +70 °C) suits outdoor or heated enclosures. The ability to parallel up to two units increases system redundancy—a key benefit for cost-sensitive ROI scenarios.
Installation & Setup Guidance
Mount the Siemens 6EP1336-1LB00 onto a DIN rail EN 60715 35x7.5/15 using the snap-on mechanism. Allow 50 mm clearance above and below for convection cooling. Use screw-type terminals for input (L, N, PE: 0.5–2.5 mm²) and output (+, -: two terminals each). Set output voltage via the potentiometer before connecting loads. For extended power, parallel two identical units; no external diodes needed—the product supports bridging.
Selection Guide & Purchasing Advice
Before ordering, verify that your system requires 24 V DC at up to 20 A and accepts universal AC/DC input. Check the ambient temperature range: derating at 2.5%/K above 45 °C. For circuit protection, use a miniature circuit breaker from 10 A characteristic C. The Siemens 6EP1336-1LB00 is stocked by PLC Source PRO (ubest101).

Troubleshooting & Common Issues
If the green LED fails to illuminate, verify input AC/DC voltage within range (85–264 V AC / 88–370 V DC) and check the feeder fuse (T 10 A/250 V). For output instability, ensure load does not exceed 20 A—overload triggers constant current limit at ~24 A. If noise appears, confirm proper grounding and that the unit is not near high-EMI sources; the Siemens 6EP1336-1LB00 meets EN 55022 Class B for emissions.
