Core Features & Benefits

→ Three-Phase Input Flexibility
Accepts 400-500VAC ±10% input range, automatically compensating for grid voltage variations without manual adjustment. Eliminates nuisance shutdowns caused by utility power fluctuations common in industrial facilities.

→ Precision Voltage Regulation
Maintains 24VDC ±3% output stability across full load range with ripple below 150mV peak-to-peak. Protects sensitive microprocessor-based controls from voltage-induced errors and premature component failure.

✓ Intelligent Overload Management
Automatic current limiting with hiccup-mode restart prevents catastrophic failure during short-circuit events. Returns to normal operation once fault clears, minimizing downtime and service calls.

✓ Thermal Performance Engineering
Operates reliably from -25°C to +70°C ambient without derating. Convection-cooled design eliminates fan maintenance while ensuring consistent output in temperature-extreme environments.

✓ Space-Optimized Architecture
70mm width conserves valuable DIN-rail real estate in crowded control panels. Delivers 240W power density in a footprint 40% smaller than legacy designs.

✓ Visual Diagnostics Integration
Dual-LED status display provides instant feedback on output voltage and overload conditions. Accelerates troubleshooting during commissioning and reduces mean-time-to-repair during service events.

Supports conveyor PLCs, barcode scanner arrays, and sortation system logic in distribution centers and parcel hubs. Provides the power reliability required for high-throughput automated logistics operations.

Technical Parameters & Selection Guide

Selection Criteria: Choose the 6EP1434-2BA00 when your application requires three-phase input capability and 10A output capacity. For single-phase 230VAC installations, consider the 6EP1334-2AA00 variant. When load requirements exceed 10A, evaluate the 6EP1336-3BA00 (20A) or 6EP1437-2BA10 (40A) models. Always size power supplies to 80% of rated capacity for optimal service life.

Extended Functions

Redundancy & High-Availability Configurations
Combine with SITOP redundancy modules (6EP1961 series) to create N+1 or 1+1 redundant power architectures. Automatic load sharing and decoupling diodes ensure seamless failover without system interruption.

Energy Storage Integration
Pair with SITOP DC-UPS systems (6EP1931 series) to bridge utility power interruptions up to several minutes. Ideal for applications requiring graceful shutdown or ride-through capability during brief outages.

Remote Monitoring Capability
Integrate with SITOP PSE200U monitoring modules for real-time power system diagnostics via PROFINET or Modbus TCP. Track voltage, current, and alarm conditions through SCADA or building management systems.

Customization Options
Factory-configurable output voltage settings available for OEM applications requiring non-standard DC voltages. Consult factory for extended temperature range (-40°C) or conformal coating options for extreme environments.

Frequently Asked Questions

What input voltage configuration does this SITOP power supply require?
The 6EP1434-2BA00 is designed exclusively for three-phase 400-500VAC input. It will not operate on single-phase 230VAC. For single-phase applications, specify the 6EP1334-2AA00 model instead.

How much capacitive load can be connected to the output terminals?
Maximum permissible output capacitance is 4700µF at 24VDC without current derating. Larger capacitor banks may trigger inrush current limiting during power-up.

Can multiple units be paralleled to increase available current capacity?
Yes, when used with SITOP redundancy modules (6EP1961-3BA21), multiple PSU100M units can be paralleled for load sharing and redundancy. Direct paralleling without decoupling modules is not recommended.

Does this power supply meet marine or hazardous location certifications?
The unit carries GL (Germanischer Lloyd) and DNV (Det Norske Veritas) approvals for marine applications. It is not certified for Class I Division 2 hazardous locations without additional enclosure protection.

What is the recommended circuit protection for the input side?
Install a 10A slow-blow fuse or C-curve circuit breaker on each input phase. Coordinate with upstream distribution protection to ensure selective tripping.

How does the unit perform during voltage sag or brownout conditions?
The power supply maintains regulated output down to 85% of nominal input voltage. Below this threshold, output voltage will drop proportionally until the under-voltage lockout activates at approximately 340VAC.
