Product Description:
The 134F7680 AC drive is produced by Danfoss within the VLT FC 103 Refrigeration Drives series. As a frequency converter tailored for compressors, condensers, and evaporator fans, it adjusts motor speed to match cooling demand. This control can lower energy consumption and reduce mechanical stress in industrial refrigeration systems. The drive supports temperature-controlled processes that require stable regulation under changing loads. Its application-focused design makes it suitable for managing common refrigeration equipment in industrial facilities.
The unit delivers a continuous output of 37 kW, or 50 HP, making it suitable for midrange screw or scroll compressor motors. Its rectifier accepts a supply range of 380–480 VAC from a three-phase network, allowing direct connection to common industrial power systems without a transformer. Thermal management relies on backplate cooling, which transfers heat away from the internal power electronics. The housing has an IP55 and Type 12 backplate rating, protecting internal components against dust and low-pressure water jets. Output regulation is managed by a pulse-width-modulated inverter that samples motor feedback at high frequency. The control system adjusts motor voltage and frequency in response to operating demand, helping the connected equipment maintain the required speed.
The factory-installed graphical local control panel displays operating parameters and alarms on a multiline screen. Power and control conductors pass through standard cable entries, providing conventional routing for installation inside the enclosure. The drive has no brake chopper, so regenerative energy must be managed by the mechanical load or suitable external braking equipment. Electromagnetic interference is reduced by the built-in Class A1/B RFI filter. The printed circuit boards do not have a protective coating, so the enclosure provides the primary barrier against moisture and airborne contaminants. Modular option slots can accommodate compatible communication or encoder cards when networked control or additional feedback functions are required. Service access is provided through the front of the enclosure, allowing the display, terminals, and available option areas to remain accessible without disturbing the backplate cooling arrangement.
