Wide Range and High Flexibility

The SD750 series forms the core platform of our product line, available from 1.5 kW to 1750 kW and for voltages between 380 V AC and 480 V AC. Offered in IP20 and IP54 enclosures, it covers the full spectrum of industrial applications, combining compact design with easy installation, commissioning, and maintenance, making it one of our most extensive and versatile ranges.

Key Features and Advanced Capabilities

• Low dV/dt to protect motor insulation and extend lifespan.
• Smart mechanical design for higher power density and space-saving installation.
• Advanced motor control algorithms for precision and efficiency.
• Removable memory unit for simple and advanced maintenance.
• Energy monitoring and analysis tools to support energy-saving processes and digital transformation initiatives.

User Interface and Control Panel

The SD750 series features an intuitive control panel with integrated WiFi connectivity, enabling simultaneous connection to multiple drives and user-friendly interaction without additional hardware.

Accessories and Customization Options

• Communication Modules & Interface Components:
  A wide range of communication options including Modbus, Profibus, Profinet, Ethernet/IP, and others, designed to meet specific industrial requirements.

• Fiber-Optic Circuit Board:
  Allows fiber-optic communication for synchronizing multiple drives in master/slave configuration (PMC – Power Motor Control), enabling coordinated control of speed or torque. Fiber optics ensure interference-free communication over long distances.

• I/O Expansion Cards:
  Optional digital and analog I/O expansion cards to integrate SD750 into any system.
  (Note: If the same card offers both analog and digital I/O, the phrase “or” would be removed for consistency.)

• Encoder Card:
  For closed-loop vector control, enhancing control accuracy. Supports differential encoders with optically isolated signals and supply voltages from 5VDC to 24VDC.

• PT100 Input Expansion:
  Enables connection of up to 8 PT100 sensors for monitoring motor or process temperatures.

• IP20 Junction Boxes:
  Optional junction boxes (sizes 1 and 3) to facilitate cable connections and compliance with installation standards regarding cable bend radius.

Mechanical and Installation Options

• Platforms and Mounting Solutions:

  • Sizes 5 and above: Floor-mounted design; optional platforms to reach total heights of 2000 mm or 2200 mm.
  • Size 4: Wall-mounted design, also adaptable to floor platforms with total height of 1712 mm.

• Paint Finishes:
  Available with special paint coatings for specific environmental requirements.

Advanced Safety and Protection

• B150 Dynamic Brake:
  Activates the IGBT when the DC bus voltage exceeds set limits, dissipating energy through external resistors for safe operation.

• Special Filters:
  Custom input and output filters, including sinusoidal filters, IT system filters, and filters for harsh environments. Contact Power Electronics for tailored solutions.

• Functional Safety Options:
  Including PT100 temperature sensors, safety cut-offs, and emergency stop systems to meet application-specific safety standards.
