6EP1336-3BA00 is a Siemens SITOP Modular DC power supply, a high-performance solution designed to deliver stable 24V DC power for large-scaleindustrial automation systems. As part of the SITOP Modular series, it is engineered for flexibility, scalability, and reliability in demanding industrial environments, making it suitable for powering complex setups with multiple high-power components. Here’s a detailed description:
-
Core Electrical Specifications:
This power supply module provides a rated output of 24V DC with a maximum current of 40A, resulting in a total output power of 960W. Its high capacity enables it to supply power to large-scale industrial components, including multiple PLCs, I/O modules, HMIs, sensors, actuators, and even small drives or motors. -
Input Characteristics:
It accepts a wide AC input voltage range of 85–264V, ensuring compatibility with global mains supplies (120V and 230V) for international applications. The input frequency spans 47–63Hz, enhancing adaptability to varying grid conditions. The rated input current is 17A (at 120V) and 8.5A (at 230V), balancing its high power output with efficient energy consumption. -
Output Performance:
- The output voltage is fixed at 24V DC with precise regulation, ensuring consistent power delivery to connected equipment—critical for the stable operation of both sensitive electronics and high-power devices.
- It maintains low output ripple (≤150mV peak-to-peak), providing clean power that minimizes electromagnetic interference (EMI), protecting communication modules, PLCs, and other precision components from signal disruption.
- The module supports short-term overloads, with a peak current capability of 60A for up to 5 seconds, accommodating temporary high-power demands during startup (e.g., of motors or solenoids) or brief operational spikes.
-
Efficiency and Protection Features:
- Achieves high efficiency (up to 90% at rated load), reducing energy loss and heat generation—essential for control cabinet setups where thermal management is critical, especially in high-power applications.
- Integrated protection mechanisms ensure system safety and durability:
- Short-circuit protection: Automatically limits current during a short circuit to prevent damage to the power supply and connected devices, with automatic recovery once the fault is resolved.
- Overload protection: Safeguards against excessive current draw beyond the 40A rating, ensuring stable operation under varying load conditions.
- Overvoltage protection: Triggers at approximately 30V to shield downstream equipment from harmful voltage spikes, a key safeguard for sensitive electronics.
- Over-temperature protection: Prevents damage from excessive heat by shutting down the unit temporarily if internal temperatures exceed safe limits, with automatic restart once cooled.
-
Design and Installation:
- Features a modular, robust design optimized for DIN rail mounting (EN 60715, 35mm width), allowing easy integration into control cabinets. Its scalable architecture supports parallel operation with other SITOP Modular units, enabling customized power solutions for even larger systems.
- A green LED indicator on the front panel illuminates when the output voltage is within the normal range, providing instant visual confirmation of operational status. Additional fault indicators (e.g., for overload or over-temperature) simplify troubleshooting.
-
Environmental and Safety Compliance:
- Operates in a temperature range of 0°C to 60°C (with derating applied above 45°C) and can be stored at -25°C to 70°C, ensuring reliability in harsh industrial climates, including dusty or moderately humid environments (up to 95% relative humidity, non-condensing).
- Withstands industrial vibration (10–57Hz, 0.15mm amplitude) and shock (15g acceleration for 11ms), ensuring durability in demanding operational environments such as manufacturing floors or process plants.
- Complies with international standards and certifications, including CE, cULus, and EMC directives (EN 61000), meeting stringent safety and electromagnetic compatibility requirements for global industrial use.
-
Typical Applications:
Suitable for large-scale industrial setups requiring high-power 24V DC distribution, such as:- Heavy-duty automation systems (e.g., automotive production lines, large assembly plants, or bulk material handling systems)
- Control rooms with multiple PLCs, I/O modules, HMIs, and communication networks
- Complex machine tools with numerous high-power actuators, sensors, and auxiliary components
- Process control systems in industries like chemicals, energy, or pharmaceuticals, where reliable high-power distribution is critical for operational continuity.
In summary, the 6EP1336-3BA00 is a high-capacity, efficient DC power supply that combines 960W output, robust protection features, and modular flexibility, making it an ideal choice for powering large, demanding industrial automation systems.
