Product Description:

KEB 14.F4.050-2009 is a frequency inverter for industrial automation that offers fine control over motor speed and torque. The inverter supports three-phase 380/400/415 V AC input and a frequency range of 50/60 Hz (±2%) for steady operation. The load capacity ranges from 130% to 200% in less than 30 seconds allowing for challenging load circumstances. KEB ensures that industry standards are met in order for operations to be reliable.

The 14.F4.050-2009 frequency inverter provides reliable power transfer with a rated current of 16.5 A. The control board's parameters regulate the frequency output that allows for exact control of speed. Because of its IP00 rating, it must be used in a controlled or sealed environment. The use of twisted or shielded wires to connect the control circuit ensures signal integrity. To reduce interference at high frequencies, attach the shield at both ends. To avoid accidents, the braking resistor must be installed properly. Its adjustable output voltage that can be set anywhere between zero and the input voltage, allows for versatile control over a wide range of applications. The suppression of interference at low frequencies must meet the VDE 0160 requirements. These measures ensure that industrial activities remain stable and free of intrusion.

The correct installation and handling of the 14.F4.050-2009 inverter are essential for ensuring operating efficiency. The inverter efficiently controls the motor's performance and keeps it within its rated power of 11 kVA and a maximum output of 7.5 kW. Installation and operational requirements must be met in order for the system to perform safely and efficiently. Placing the inverter in a controlled environment ensures that it is protected from external forces. The inverter adheres to strict electrical and interference suppression standards to ensure consistent performance.

Frequently Asked Questions about 14.F4.050-2009:

Q: Do KEB 14.F4.050-2009 power lines require shielding?

A: Yes, power and control lines should be installed separately. Shielding reduces electromagnetic interference, ensuring stable and noise-free operation.

Q: How does KEB 14.F4.050-2009 handle voltage fluctuations?

A: The inverter operates within a ±10% voltage tolerance. This ensures stable performance even with minor supply variations.

Q: Why does KEB 14.F4.050-2009 need a braking resistor?

A: The braking resistor dissipates excess energy during deceleration. This prevents overheating and ensures controlled motor stopping.

Q: Does KEB 14.F4.050-2009 require altitude-based power adjustments?

A: Yes, power is reduced by 1% per 100 meters above 1000 meters. This compensates for reduced cooling efficiency at higher altitudes.

Q: How do VDE 0160 standards improve KEB 14.F4.050-2009?

A: Compliance with VDE 0160 suppresses low-frequency interference. This maintains signal integrity and ensures reliable operation in electrical networks.
