Product Description:
The 178F0665 is a frequency converter produced by Danfoss for the VLT 2800 Low Voltage Drives series. Delivered as a standalone controller, it mounts on a DIN rail or inside a cabinet and governs asynchronous motors used in water treatment, HVAC, and general process machinery. By varying output frequency and voltage, the device allows precise adjustment of shaft speed, reduces energy consumption, and supports closed-loop control without mechanical throttling components. Its slim housing is suitable for retrofit projects where cabinet space is limited.
The drive’s power stage is rated at 1.5 kW, which corresponds to a shaft capacity of 2.0 HP. It accepts a mains supply of 380–480 V, ±10%, at 50/60 Hz over a three-phase network, allowing direct connection to typical industrial feeders without a transformer. An internal rectifier and IGBT bridge produce the variable-frequency output required to regulate motor operation. The IP20 protection rating makes the converter suitable for installation in clean, enclosed panels that prevent direct contact with internal electrical components. The standard configuration is intended for process applications, and the terminal strip provides the primary interface for start, stop, and reference signals because no application option module is installed.
The housing uses a Bookstyle format, allowing multiple drives to be installed side by side with minimal clearance while sharing airflow within the cabinet. A built-in display (SLCP) on the front bezel shows operating status, alarms, and parameter values without requiring an external programming device. The circuit boards have a protective coating that improves resistance to humidity, dust, and other airborne contaminants. Conducted emissions are limited by an integral RFI filter that complies with EN 55011 Class A1, supporting use at industrial sites with applicable electromagnetic compatibility requirements. No fieldbus option is installed, so control commands and reference signals remain hardwired through the converter’s terminals.
