Product Description:

For use in industrial automation, KEB produces motor chokes with exceptional performance. When it comes to high-frequency uses, the 27.Z2.F04-1003 Motor Choke is built to last. With a maximum installation altitude of 2000m, a derating factor of 1% every 100m applies above 1000m. Forced air cooling is essential to maintain peak performance at high operating frequencies.

At 600 Hz, the 27.Z2.F04-1003 motor choke loses 515 W of power, and at 800 Hz, it increases to 852 W.A temperature switch (NC) is included and must be connected to the drive converter terminals T1/T2 to ensure proper thermal monitoring. Operating at 400/480V, the motor choke is ideal for freestanding installations. Easy integration into electrical systems is made possible by the choke's dimensions of 180 mm in height and 465 mm in width. When the operating frequency goes beyond 600 Hz, the choke needs more airflow to keep from being too hot. The installation position is standing, and the choke is designed to satisfy application specifications with precise thermal and electrical qualities. With a recommended maximum of 104°F, the choke works in an ambient temperature range of 14 to 113°F. Its forced air cooling system guarantees effective thermal management in demanding applications.

The 27.Z2.F04-1003 motor choke is designed for stability and long-term operation. The motor choke preserves performance at the preset settings while displaying precise power loss metrics. Transport and handling are both made possible by the storage temperature range of -13 to 131°F. The motor choke, when not condensing, is capable of withstanding relative humidity values between 5 percent and 85 percent. The choke's reliable electrical performance and easy integration into motor control systems make it an ideal component for use in industrial automation.

Frequently Asked Questions about 27.Z2.F04-1003:

Q: How does the 27.Z2.F04-1003 handle altitude limitations?

A: It operates at a maximum altitude of 2000m. A 1% derating factor applies per 100m beyond 1000m to maintain electrical efficiency.

Q: Do storage and operating temperatures differ for 27.Z2.F04-1003?

A: Yes, the storage temperature ranges from -13 to 131°F. The operating temperature is limited to 14 to 113°F, with 104°F recommended.

Q: Why is the installation position of 27.Z2.F04-1003 standing?

A: The design supports optimal heat dissipation and mechanical stability in a standing position. This ensures reliability and performance consistency in motor control systems.

Q: Does the 27.Z2.F04-1003 support high humidity conditions?

A: It operates in relative humidity levels from 5% to 85% (non-condensing). This prevents moisture-related damage and ensures long-term durability.

Q: Why does the 27.Z2.F04-1003 require ventilation above 600 Hz?

A: Power loss increases significantly at higher frequencies, generating excess heat. Ventilation ensures effective thermal dissipation and prevents damage to internal components.
