Siemens 6EP1333-3BA10 SITOP PSU200M 24VDC 5A Stabilized Power Supply

1. Overview of the Siemens 6EP1333-3BA10

The SITOP PSU200M model 6EP1333-3BA10 is a 120 W DIN rail switching power supply from Siemens. It converts a single-phase or two-phase 85–264 V AC wide-range input into a stable 24 V DC/5 A output. With an overall efficiency of up to 88%, a ripple of only 50 mV, and a load regulation accuracy of 0.1%, it provides a clean and reliable DC bus for industrial field devices such as PLCs, HMIs, sensors, and actuators.

Enclosed in a compact 70 × 125 × 121 mm metal housing, this power supply operates at full load in an ambient temperature range of –25°C to +70°C without requiring side heatsink clearances. A built-in potentiometer allows fine-tuning of the output between 24–28.8 V to compensate for line voltage drops. A green "24 V OK" LED and relay contacts are integrated on the front panel, providing real-time power status reporting and facilitating remote diagnostics via a host computer.

2. Main Features
Wide Voltage Adaptation: Plug-and-play compatible with global power grids, supporting 120 V, 230 V, 400 V, and two-phase 500 V systems.
Power Boost & Extra Power: Instantaneously delivers 15 A (25 ms) or 7.5 A (5 s) to start motors, relays, or capacitive loads, eliminating the need to increase power supply capacity. Intelligent Protection: Five levels of protection: short circuit, overload, overvoltage, overtemperature, and undervoltage (brownout); user-selectable short-circuit response modes: constant current limiting or latching shutdown.
Remote Monitoring: A green "24 V OK" LED and relay dry contacts (60 V/0.3 A) on the front panel enable real-time power status alarms via PLCs and SCADA systems.
Parallel Redundancy: Supports parallel operation with two units for current sharing, and can be upgraded to 1+1 hot standby with an external redundancy module, improving system availability.
Compact Heat Dissipation: The metal housing utilizes natural convection, eliminating the need for heat dissipation gaps on either side and saving cabinet space.

3. Typical Applications
• Factory Automation: Provides a 24 V bus for PLCs, HMIs, inverters, and distributed I/O.
• Process Control: In chemical and water treatment applications, ATEX/IECEx certification allows for direct installation in Zone 2 explosion-proof areas. • New Energy and Transportation: Wide-voltage input ensures continuous operation in scenarios with severe power grid fluctuations, such as photovoltaic power plants and electric bus charging stations.
• High-end Equipment: Five-axis machining centers, SMT placement machines, and other precision equipment utilize low ripple and Power Boost features to improve machining accuracy and equipment life.
