Product Description:

The Danfoss VLT 6000 frequency converter is designed for HVAC applications that require motor control. This 178B2022 frequency converter body is made of brushed metal, along with LED lights that show when it is ON, in alarm, or in warning.

The 178B2022 frequency converter cools itself with forced air, which comes in through the front and bottom and goes out through the holes in the back. While the power terminals of the converter are capable of handling a three-phase input of 380–460V at 50/60Hz, the maximum input current that they can manage is 12.2A. On black blocks that also have analog and digital input and output connections, the control and secondary relay terminals are mounted. A protective cover that has a gray metallic top and a black interface region serves to shield the components that are located on the inside. There are several conduit entry points and grille cutouts at the back and bottom to keep air moving and keep the wires organized. The signal that is produced is a three-phase signal, and its frequency can be adjusted anywhere from 0 to 100 hertz. The current rates range from 13A to 11A., and the power capacity is 9.3 kVA depending on the load.

The 178B2022 frequency converter comes with an IP20 shell that protects the open frame. The system is designed to work in temperatures as high as 45°C. It is possible to put panels in a stable manner due to the flat mounting base. The frequency converter is used in HVAC systems that require frequency control because of these specifications. The frequency converter is set up to work reliably and accurately regulate motors in HVAC and industrial control settings.

Frequently Asked Questions about 178B2022:

Q: Does 178B2022 benefit from the fan cooling system design?

A: Yes, the fan cooling system maintains stable operating temperatures. It draws air through front openings and exhausts through the rear that ensures reliable performance under load.

Q: Why does 178B2022 feature analog and digital input terminals?

A: Analog and digital terminals allow flexible HVAC control. They enable sensor connections and communication signals that enhance motor regulation and integration into building automation systems.

Q: How do 178B2022 heavy-duty terminals improve wiring connections?

A: Heavy-duty terminals provide robust input and output connections. They ensure stable power transfer that supports three-phase 380–460V operation and minimizes electrical resistance at high current.

Q: Why does 178B2022 include LED indicators on the front panel?

A: LED indicators show ALARM, WARNING, and ON status. They allow quick visual monitoring that improves diagnostics and reduces downtime during operation and maintenance cycles.

Q: Do 178B2022 ventilation grilles support long-term product reliability?

A: Yes, ventilation grilles allow continuous airflow that prevents overheating. They keep internal components within the rated temperature range and extend the operational lifespan of the drive.
