Manufacturing facilities, process plants, and infrastructure systems worldwide depend on SITOP technology to eliminate voltage sag, suppress electrical noise, and maintain continuous operation during grid fluctuations. Whether you're powering a Siemens S7-1500 controller network, integrating third-party automation components, or building redundant power architectures, the 6EP1436-2BA10 delivers the reliability and performance industrial engineers demand.

With global safety certifications (CE, UL, cULus, ATEX), compact DIN-rail mounting, and diagnostic LED indicators, this power supply simplifies installation while providing real-time operational visibility. Its 93% typical efficiency reduces heat generation and energy costs, while built-in protection mechanisms safeguard downstream equipment from overcurrent, short-circuit, and thermal events.

Core Features & Benefits

✓ Precision Voltage Regulation: Maintains ±1% output accuracy across 0-100% load range, protecting sensitive microprocessor-based controls from voltage-induced errors and extending component lifespan in harsh industrial environments.

✓ Wide Input Voltage Tolerance: Accepts 400-500V AC three-phase input with automatic compensation for frequency variations (50/60 Hz), enabling deployment across international facilities without voltage-specific procurement or inventory complexity.

✓ Active Power Factor Correction (PFC): Achieves >0.95 power factor to minimize reactive power consumption, reduce utility demand charges, and comply with energy efficiency regulations in commercial and industrial installations.

✓ Intelligent Overload Management: Electronic current limiting with automatic restart capability prevents nuisance shutdowns during motor inrush or capacitive charging events, while thermal monitoring ensures safe operation up to 70°C ambient temperature.

✓ Redundancy-Ready Architecture: Supports parallel operation with Siemens 6EP1961/6EP1962 redundancy modules for N+1 configurations, delivering fault-tolerant power to safety-critical systems without single points of failure.

→ Diagnostic LED Array: Provides instant visual confirmation of DC output status, overload conditions, and input voltage presence, accelerating troubleshooting and reducing mean time to repair (MTTR) during maintenance activities.

Application Scenarios

Automated Manufacturing Lines: Powers robotic welding cells, CNC machine tool controls, and conveyor systems where voltage stability directly impacts product quality and production throughput. The unit's fast transient response prevents PLC scan errors during high-speed switching operations.

Process Control & SCADA Systems: Supplies reliable energy to distributed control systems (DCS) in chemical processing, water treatment, and oil & gas facilities where unplanned downtime translates to significant revenue loss and environmental compliance risks.

Building Automation & Infrastructure: Energizes HVAC controllers, access control panels, and fire alarm systems in commercial buildings, data centers, and transportation hubs requiring 24/7 uptime and compliance with life-safety codes.

Renewable Energy & Microgrid Applications: Integrates with battery storage systems, solar inverters, and wind turbine controllers where grid instability demands robust power conditioning and wide operating temperature ranges.

Machine Tool & Packaging Equipment: Delivers clean DC power to servo drives, HMI panels, and vision inspection systems in high-precision manufacturing environments sensitive to electrical noise and voltage ripple.

Technical Parameters & Selection Guide

Selection Criteria: Calculate total connected load including 20-30% safety margin for future expansion. For single-phase input requirements, consider the SITOP PSU100S series. Applications demanding higher current should evaluate the 6EP1437-2BA10 (40A model). Redundant systems require pairing with 6EP1961-3BA21 or 6EP1962-2BA00 redundancy modules.

Extended Functions

Remote Monitoring Integration: When combined with SITOP communication modules (6EP1972-2BA00), the power supply transmits diagnostic data via PROFINET or Modbus TCP to SCADA systems, enabling predictive maintenance strategies based on load trends, temperature monitoring, and operating hour tracking.

Parallel Operation Capability: Multiple units can be configured for current sharing or redundancy using external SITOP modules, supporting scalable power architectures from 20A to 160A+ without redesigning control cabinet layouts.

Customization Options: Factory-configured output voltage settings, extended temperature ratings (-40°C to +70°C), and conformal coating for harsh environments are available through Siemens Industry Mall or authorized distributors for specialized applications.

Delivery & Service Assurance

Lead Time: Standard stock items ship within 3-5 business days. Custom configurations require 4-6 weeks manufacturing lead time. Expedited delivery available for critical projects.

Warranty Coverage: Comprehensive 12-month manufacturer warranty covering defects in materials and workmanship. Extended warranty programs available through authorized service partners.

Technical Support: Access to Siemens global support network including application engineering consultation, system integration guidance, and 24/7 technical hotline for troubleshooting assistance.

Frequently Asked Questions

Q: What is the recommended wire gauge for 20A output connections?
A: Use minimum 12 AWG (4mm²) copper conductors rated for 90°C. Torque output terminals to 0.8-1.2 Nm. Ensure proper strain relief and maintain minimum bend radius per NEC/IEC standards.

Q: Can this power supply operate in single-phase input mode?
A: No, the 6EP1436-2BA10 requires balanced three-phase input. For single-phase 230V AC applications, specify the 6EP1336-2BA10 from the SITOP PSU100S series with equivalent 20A output rating.

Q: How do I calculate required power supply capacity for my PLC system?
A: Sum the current draw of all connected devices (CPU, I/O modules, sensors, indicators) and add 25-30% margin. For example, a system drawing 15A continuous should use this 20A unit to accommodate inrush currents and future expansion.

Q: What redundancy configuration provides the highest availability?
A: Deploy two 6EP1436-2BA10 units with a 6EP1961-3BA21 redundancy module in N+1 configuration. This architecture maintains full 20A capacity even if one power supply fails, achieving >99.99% uptime for critical processes.

Q: Does the unit support remote on/off control?
A: Yes, the power supply includes a remote shutdown input terminal. Applying 24VDC to this terminal disables output, enabling integration with emergency stop circuits or energy management systems.

Q: What is the typical noise immunity performance?
A: The unit meets IEC 61000-4-4 (EFT) Level 4 and IEC 61000-4-5 (surge) Level 3 requirements, providing robust immunity to electrical fast transients and surge events common in industrial environments with motor drives and contactors.
