Core Features & Benefits

→ High-Efficiency Power Conversion
Achieves >92% efficiency at nominal load, reducing energy costs and minimizing heat dissipation in control cabinets. This translates to lower cooling requirements and extended component lifespan.

→ Comprehensive Protection Architecture
Integrated short-circuit, overload, and overvoltage protection safeguards both the power supply and connected equipment. Automatic recovery functionality reduces downtime and maintenance interventions.

→ Wide Input Voltage Range
400-500V AC three-phase input accommodates global power standards and compensates for grid fluctuations, ensuring stable operation across diverse installation sites.

→ Parallel Operation Capability
Supports redundant configurations for critical applications requiring N+1 backup power. Multiple units can be paralleled to increase total current capacity beyond 40A.

→ Adjustable Output Voltage
22.8-28.8V DC adjustment range allows fine-tuning to match specific equipment requirements and compensate for voltage drops in long cable runs.

→ Diagnostic LED Indicators
Visual status feedback enables rapid troubleshooting and reduces mean time to repair (MTTR) during maintenance operations.

Typical Application Scenarios

Manufacturing Assembly Lines
Powers pneumatic valve manifolds, proximity sensors, and PLC control systems in automotive and electronics production facilities. Eliminates voltage sag issues that cause false sensor readings and production errors.

Process Control Systems
Supplies stable power to distributed control systems (DCS) in chemical processing, water treatment, and food & beverage plants. The wide operating temperature range (-25°C to +70°C) handles extreme ambient conditions.

Packaging Machinery
Drives servo controllers, HMI panels, and safety relay modules in high-speed packaging equipment. Parallel operation provides redundancy for 24/7 continuous operation requirements.

Material Handling Systems
Energizes conveyor controls, barcode scanners, and RFID readers in warehouse automation and logistics centers. Conformal coating option protects against dust and moisture in non-climate-controlled environments.

Machine Tool Control Panels
Provides clean DC power for CNC controllers, spindle drives, and tool changers in metalworking operations. Low ripple voltage ensures precision in motion control applications.

Technical Parameters & Selection Guide

Selection Criteria:

✓ Calculate total current draw of all connected devices and add 20% safety margin
✓ Verify input voltage matches your facility's power distribution (3-phase required)
✓ Consider ambient temperature and ensure adequate ventilation for cabinet installation
✓ For redundant systems, select two units and configure for parallel operation
✓ Choose conformal coating version for environments with humidity >85% or airborne contaminants

Extended Functions

Frequently Asked Questions

What is the difference between SITOP POWER and SITOP PSU series?
The POWER series offers higher current ratings (20A-40A) with three-phase input, while PSU series provides single-phase input options for lower current applications (5A-20A). POWER units deliver better efficiency for high-capacity installations.

Can I use this power supply with single-phase input voltage?
No, the 6EP1437-2BA10 requires three-phase 400-500V AC input. For single-phase applications, consider the 6EP1336 series which accepts 120-230V AC single-phase input.

How do I configure parallel operation for redundancy?
Connect the positive outputs together and negative outputs together using appropriately sized cables. Each unit automatically shares the load current. Install decoupling diodes (6EP1961-2BA00) to prevent reverse current flow during single-unit failure.

What cable size is recommended for 40A output connections?
Use minimum 10 AWG (6mm²) copper wire for output connections up to 3 meters. For longer cable runs, increase wire gauge to compensate for voltage drop (consult voltage drop calculator for specific distances).

Does this unit support remote on/off control?
Yes, terminals 11-12 provide remote enable/disable functionality. Apply 24V DC signal to enable output, or leave open/short to ground for local control mode.

How can I monitor power supply status remotely?
Install SITOP Manager software and connect via Ethernet using the optional communication module (6EP1972-2BA00). This enables real-time monitoring of output voltage, current, temperature, and alarm conditions.
