6EP1336-2BA10 is a Siemens SITOP Modular DC power supply, part of the SITOP Modular series known for its flexibility, high performance, and robust design, tailored for demanding industrial automation environments. This power supply is engineered to deliver stable 24V DC power, supporting a range of industrial devices with reliable and efficient energy distribution. Here’s a detailed breakdown:
-
Core Electrical Specifications:
The module provides a rated output of 24V DC with a maximum current of 20A, resulting in a total output power of 480W. This higher power capacity makes it suitable for larger-scale industrial setups, powering multiple components such as PLCs, I/O modules, sensors, actuators, HMIs, and even small motors or drives. -
Input Characteristics:
It accepts a wide AC input voltage range of 85–264V, ensuring compatibility with global mains supplies (120V and 230V) for international use. The input frequency spans 47–63Hz, enhancing adaptability to varying grid conditions. The rated input current is 8.5A (at 120V) and 4.2A (at 230V), balancing its high power output with efficient energy draw. -
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 sensitive electronics and high-power devices alike.
- 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 30A 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—advantageous 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 20A 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, space-efficient design optimized for DIN rail mounting (EN 60715, 35mm width), allowing easy integration into control cabinets with limited space. Its robust construction supports seamless integration into existing SITOP Modular systems, enabling scalable power solutions (e.g., parallel operation for higher power needs).
- 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 for quick diagnostics. Additionally, it may include fault indicators (e.g., for overload or over-temperature) to 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 high-power industrial setups requiring reliable 24V DC power, such as:- Large-scale automation systems (e.g., automotive production lines, heavy machinery, or bulk material handling systems)
- Control panels with multiple PLCs, I/O modules, HMIs, and communication devices
- Machine tools with high-power actuators, sensors, and auxiliary components
- Process control systems in industries like chemicals, food and beverage, or pharmaceuticals, where stable power is critical for regulatory compliance.
In summary, the 6EP1336-2BA10 is a high-performance, flexible DC power supply that combines 480W capacity, robust protection features, and efficient operation, making it an ideal choice for powering demanding industrial automation systems requiring reliable 24V DC power.
