NEW 6EP1437-2BA20

Core Electrical Parameters

• Input:
  • Three-phase AC: 320–575V AC (47–63Hz), compatible with global industrial grids (nominal 400–500V AC).
  • Input current: 2.1A at 400V AC, 1.7A at 500V AC, ensuring efficient power draw across voltage ranges.
• Output:
  • Adjustable 24V DC: Rated at 40A (960W), with voltage adjustable from 24–28.8V DC to offset voltage drops in long cable runs.
  • Voltage stability: ±1% regulation under varying loads, with low ripple/noise (≤100mV peak-to-peak) to protect sensitive electronics.

Performance & Power Management

• Power Boost: Delivers 1.5× rated current (60A) for up to 5 seconds to handle inrush currents from motors, solenoids, or other high-startup devices.
• Efficiency: Reaches 94% efficiency at full load, reducing energy waste and minimizing heat generation in control cabinets.
• Overload Handling:
  • Constant Current Mode: Maintains output at reduced current during sustained overloads.
  • Latch-Off Mode: Disables output until the fault is manually reset (selectable via DIP switch) for critical applications.

Protection & Monitoring

• Comprehensive Safeguards:
  • Short-circuit protection with automatic recovery after fault clearance.
  • Overvoltage protection (triggers at ~30V) to shield downstream equipment from voltage spikes.
  • Over-temperature shutdown with self-resetting capability to prevent damage from excessive heat.
• Status Indicators:
  • Green LED for normal operation; red LED for fault conditions (overload, overtemperature, or overvoltage).
  • Compatible with optional signaling modules (e.g., 6EP1961-3BA00) for remote monitoring and remote ON/OFF control.

Design & Installation

• Compact Dimensions: Measures 100mm (W) × 121mm (H) × 125mm (D), designed for 35mm DIN rail mounting (EN 60715) to save space in control cabinets.
• Durable Construction: IP20-rated metal enclosure resists dust and mechanical stress, withstanding vibrations (10–57Hz, 0.15mm amplitude) and shocks.
• Scalability:
  • Parallel Operation: Supports load-sharing with up to 4 units for higher power output (e.g., 160A with 4 modules).
  • Redundancy Ready: Works with SITOP redundancy modules (e.g., 6EP1961-2BA00) to create fault-tolerant systems for critical applications.

Environmental & Compliance

• Operating Temperature: 0°C to +60°C (with derating above 50°C to ensure reliability).
• Storage Temperature: -40°C to +85°C, suitable for harsh storage conditions.
• Certifications: CE, cULus, EMC compliance (EN 61000), and marine approvals (ABS, DNV) for global industrial and maritime applications.
• EMC Performance: Meets EN 55022 Class B standards, minimizing electromagnetic interference with nearby equipment.

Typical Applications

• Powering PLCs, HMIs, and distributed I/O systems in manufacturing lines.
• Supporting high-current devices like servo drives, robotics, and large sensor networks.
• Critical infrastructure where redundancy and stable power are essential (e.g., process control in chemical plants, energy production facilities).

Key Benefits

• Universal Input: Adapts to global three-phase grids, eliminating the need for voltage converters.
• Flexible Voltage Adjustment: Ensures stable power delivery even with long cable lengths.
• High Efficiency: Reduces energy costs and extends component lifespan by minimizing heat.
• Robust Protection: Safeguards both the power supply and connected equipment from electrical faults.
