As part of Siemens’ SITOP Smart series, it is engineered to meet the demands of industrial environments with a focus on performance, efficiency, and robust protection. Here’s a detailed description:
-
Core Electrical Specifications:
This power supply module provides a rated output of 24V DC with a maximum current of 20A, resulting in a total output power of 480W. It is specifically designed to supply consistent power to critical industrial components such as PLCs, sensors, actuators, and complex control systems. -
Input Characteristics:
It supports a wide AC input voltage range of 85–132V/170–264V, ensuring compatibility with global mains supplies (120V and 230V). The input frequency ranges from 47–63Hz, enhancing its adaptability to varying grid conditions. The rated input current is 8.4A (at 120V) and 4.6A (at 230V), making it suitable for diverse electrical infrastructures. -
Output Performance:
- The output voltage is adjustable within a small range (typically 22.8–25.2V) to accommodate specific system requirements, ensuring flexibility for different connected devices.
- It maintains low output ripple (≤150mV peak-to-peak), delivering clean power that minimizes interference with sensitive electronics, which is critical for precision equipment.
- The module can handle short-term overloads, with a peak current capability of 24A for up to 5 seconds, supporting temporary high-power demands from connected devices during startup or operation.
-
Efficiency and Protection Features:
- Boasts high efficiency (up to 89% at rated load), reducing energy loss and heat generation—an important feature for compact control cabinet setups where heat management is key.
- Integrated protection mechanisms include:
- Short-circuit protection: Automatically limits current during a short circuit to prevent damage to the power supply and connected equipment.
- Overload protection: Safeguards against excessive current draw beyond the 20A rating, ensuring system stability.
- Overvoltage protection: Triggers at approximately 33V to shield downstream devices from harmful voltage spikes.
- Over-temperature protection: Temporarily shuts down if internal temperatures exceed safe limits, resuming operation once cooled to prevent permanent damage.
-
Design and Installation:
- Features a compact, space-saving design with dimensions optimized for DIN rail mounting (EN 60715, 35mm width), making it easy to integrate into control cabinets with limited space.
- The front panel includes a green LED indicator that illuminates when the output voltage is within the normal range, providing quick visual confirmation of operational status for easy 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 -20°C to 70°C, ensuring reliability in varying industrial climates.
- Withstands industrial vibration (10–57Hz, 0.15mm amplitude) and shock (15g acceleration for 11ms), ensuring durability in harsh operational environments.
- Complies with international standards and certifications, including CE, cULus, FM, and ATEX, meeting stringent safety, electromagnetic compatibility (EMC), and hazardous area requirements.
-
Typical Applications:
Suitable for powering components in large-scale industrial automation systems, such as:- High-power factory automation lines (e.g., automotive assembly, heavy machinery production)
- Robotic workcells and advanced material handling systems
- Process control systems with multiple sensors, actuators, and I/O modules
- Control cabinets housing PLCs, HMIs, and complex automation equipment
In summary, the 6EP1333-3BA10 is a high-capacity, efficient power supply that combines reliability, compact design, and robust protection, making it an ideal solution for powering 24V DC industrial equipment in demanding, high-power applications.
