The PowerFlex 700 model 20BD156A3NNNANA0 offers precise control for various motor applications, rated at 125 HP and 100 HP for effective performance. This adjustable-frequency AC drive is engineered to work with a three-phase input supply of 480 V AC, supporting continuous output currents up to 156 A. The drive utilizes a V/Hz control scheme coupled with sensorless vector technology for adaptable motor management. Featuring an LCD keypad, the user interface allows for intuitive operation and easy configuration.
This unit is designed with a maximum internal power loss of approximately 443 W and uses a control supply voltage of 24 V DC to power its operations effectively. It does not come equipped with a brake transistor nor a resistor module, making it streamlined for specific control scenarios. The IP20 rating denotes that it is suitable for enclosed environments where minimal exposure to dust and moisture occurs. Furthermore, the drive maintains compliance with electromagnetic compatibility standards with the addition of a CE filter. Although it lacks feedback options and internal communication capabilities, it provides a solid foundation for analog and digital I/O connections, with 2 AI, 6 DI, and 3 DO available for integration with external devices.
