PowerFlex 750 AC Drives

PowerFlex 750 AC Drives

The PowerFlex 750-Series is a robust family of AC drives that provide ease of use, flexibility, and performance for various industrial applications.

PowerFlex 753 drives provide general-purpose control for applications up to 400 Hp and 270 kW.

PowerFlex 755 drives provide maximum flexibility and performance up to 2000 Hp and 1500 kW.

Maximize your productivity by taking advantage of these key features that are offered in the PowerFlex 750-Series drives:

• DeviceLogix™ – Embedded control technology that supports the manipulation of discrete outputs and drive control functions, while using discrete inputs and drive status information on board the drive.

• Predictive Diagnostics– Tracks information that affects the life of the drive cooling fans and relay outputs. The drive can also be programmed to monitor the runtime hours for machine or motor bearings.

• Option Cards– Each drive has a slot-based architecture. Supported hardware control options are available for both products, to help reduce your inventory and spare parts requirements.

• Safe Torque Off, Safe Speed Monitor, Integrated Safety – Safe Torque Off, and Integrated Safety FunctionsOption– Provides a choice for safety levels depending on your application requirements.
• Communication– The PowerFlex 755 drives come with a built-in Ethernet port. Ethernet can easily be added tothe PowerFlex 753 drives with a communication module.
• I/O– Option cards are available for additional analog and digital I/O. The PowerFlex 753 drives come with builtin I/O that can also be expanded with option cards.
• Packaging– Factory and field-installable enclosure options are available to meet most environmentalrequirements. Options include Open Type and flange mount to support cabinet mount requirements, extra protection wall-mount for harsh environments, and debris hoods and conduit plate kits.
• Standard Power Structure– A common power structure is shared to provide the same physical size and powerrange.

PowerFlex 753 Core Capabilities

1. Power Range & Voltage

   • Power: 0.75–250 kW (1–350 HP)

   • Voltage: 380–480V AC, 3-phase (±10%)

   • Frame Sizes: FRN 1–9 (Compact), FRN 10–12 (Modular).

2. Advanced Control Modes

   • Volts/Hertz (V/Hz): Basic speed control for pumps, fans.

   • Sensorless Vector Control: High-torque/low-speed precision (150% torque at 0.5 Hz).

   • Closed-Loop Vector: Encoder feedback for dynamic applications (e.g., centrifuges, conveyors).

3. Integrated Safety

   • Safe-Off Torque (STO): SIL 3/PLe safety via firmware (no external relays needed).

   • Safe-Speed Monitor (SSM): SIL 2 speed validation.
