Selection Criteria: Calculate total current draw of all connected devices and add 20% safety margin. For applications requiring redundancy, consider parallel operation with SITOP diode modules. In environments exceeding 60°C ambient, implement forced ventilation or select higher-capacity models with derating curves. For three-phase input requirements, evaluate the 6EP1437-3BA00 variant.
Modular Expansion Options
Compatible with SITOP buffer modules (6EP1961 series) for ride-through during brief power interruptions, and selectivity modules (6EP1961-3BA00) for intelligent load management. Expansion modules connect via standardized bus interface without additional wiring.
Parallel Redundancy Configuration
Multiple units can be combined using diode modules (6EP1961-2BA00) to create N+1 redundant architectures. If one supply fails, remaining units automatically share the load without system interruption, ideal for critical process control applications.
Remote Monitoring Integration
When paired with SITOP communication modules, enables integration with PROFINET, Modbus TCP, or SNMP networks for predictive maintenance. Real-time monitoring of output voltage, current, and temperature supports Industry 4.0 initiatives and reduces unplanned downtime.

What wire gauge should I use for 20A output connections?
Use minimum 14 AWG (2.5mm²) copper wire for output terminals to handle 20A continuous current. For runs exceeding 10 meters, increase to 12 AWG (4mm²) to minimize voltage drop. Torque output terminals to 0.5-0.6 Nm.
Can this power supply operate in hazardous area classifications?
The unit itself is not rated for Zone 1/2 or Division 1/2 installation. However, it can supply power to intrinsically safe barriers and isolators mounted in safe areas that interface with hazardous zone equipment. Consult ATEX documentation for specific applications.
How much energy cost reduction can I expect from 93% efficiency?
Compared to older 85% efficient supplies, the 6EP1436-3BA00 reduces wasted energy by approximately 50%. At $0.12/kWh and continuous 15A load, annual savings approach $45 per unit while generating 35W less heat in your control cabinet.
Does the unit require external fusing on the input side?
Yes, install a 10A slow-blow fuse or circuit breaker on the AC input line per NEC/IEC requirements. This provides branch circuit protection and facilitates safe disconnection during maintenance. The power supply has internal input protection but external overcurrent devices are mandatory for code compliance.
Is the output voltage adjustable for 12V or 48V applications?
No, the 6EP1436-3BA00 provides fixed 24V DC output only. For 12V requirements, consider the 6EP1332 series. For 48V applications, evaluate the 6EP1438 series or use DC-DC converters downstream.
What is the typical MTBF rating for this power supply?
Siemens specifies >500,000 hours MTBF at 40°C ambient and 80% load per SN 29500 calculation method. This translates to approximately 57 years of continuous operation under typical industrial conditions, though capacitor aging typically drives replacement at 10-15 year intervals.
