Product Description:

The Danfoss VLT® AutomationDrive FC-301 Series is made for fine motor control in factory automation. The 131B1328 frequency inverter works with voltages between 380 and 480 VAC and can connect to three-phase circuits. The design allows for simple customization, with standard cable entry points and no extra A or B choices.

The 131B1328 frequency converter can handle up to 0.37 kW (0.50 HP) of power and 1.2 A of steady current. The converter can also handle 1.3 A of high overload. The frequency converter comes with a D option MCB-107 that provides a 24V DC backup power source. The type of housing is an IP20 chassis, which allows for open mounting options. The width is 150 mm when there are two C alternatives, but it is only 90 mm when there are no C options. A brake safe stop and a brake chopper are present in the brake configuration, which facilitates the management of stopping activities. The software's most recent standard version was released. The converter comes with a standard language pack and no other software choices. The design also has a PCB that is not coated and no LCP screen.

In high overload mode, the unit loses 35 W of power. It is part of the FC-301 series group. The global standard for the frequency inverter is set so that it works with computers all over the world. The converter has an RFI filter with a Class A1/B (C1) rating that makes sure it meets standards for electromagnetic compatibility. The depth is 205 mm, and it can be increased to 220 mm by selecting A/B. Its height is 268 millimeters. A2 is the frame measurement, which simplifies the process of fitting.

Frequently Asked Questions about 131B1328:

Q: Why does the 131B1328 include an MCB-107 24V DC backup in option D?

A: The backup option maintains control functions during mains failure. It protects the drive’s internal systems, ensures uninterrupted logic operation, and secures safe handling of loads in critical operations.

Q: Does the 131B1328 drive’s IP20 chassis enclosure provide installation advantages?

A: Yes, the IP20 chassis provides protection against accidental contact. It simplifies mounting, allows flexible integration into electrical panels, and reduces space requirements while maintaining accessibility for maintenance.

Q: How does the 131B1328 manage intermittent current levels of 1.92 A and 2.08 A?

A: The drive delivers higher short-term current to handle peak demands. This supports transient loads, ensures motor acceleration under varying torque, and provides efficient operation without oversizing the equipment.

Q: Why does the 131B1328 operate within a mains voltage range of 380 to 480 VAC?

A: The wide voltage range allows compatibility with common supply networks. It ensures reliable drive performance, reduces installation complexity, and provides flexibility for integration across diverse electrical infrastructures.

Q: Do the compact dimensions of the 131B1328 frequency converter improve installation flexibility?

A: Yes, with a 90 mm width and 268 mm height, the unit fits limited spaces. Compact sizing reduces panel footprint, simplifies system design, and supports efficient layout configurations.
