Product Description:

The 134U3280 is another FC302 drive developed, designed, and manufactured by Danfoss for refrigeration systems and applications. With its robust device enclosure, this drive features a standard set of function and operational keys on its front panel. Like other FC302 converters, this unit employs an A3 enclosure, having a protection category of IP 20. With this type of protection classification, the drive can prevent accidental finger touch and the intrusion of small particles. It is, however, not immune to the ingress of dust particles. Like all other frequency converters, this electrical module requires a three-phase power supply to operate properly.

In Danfoss’ official documentation and datasheets, the 134U3280 has the model code FC-302P1K1T7E20H4BGCXXXSXXXXA0BXC4XXXDX. At nameplate voltage, this device can deliver a high-overload output power of 1.1 kilowatts. As a T7 frequency converter, this module is intended for high-voltage operation. Specifically, the voltage range for this drive’s input terminals can go as high as 525 to 690 VAC. With this line power supply, the drive can draw a continuous input current of 1.4 to 1.9 A. To accommodate such continuous current, the recommended cable cross section for this module should at least be 4 square millimeters for every wire.

At high-overload conditions, the 134U3280 can incur an estimated power loss of around 44 watts. With this power loss rating, the module achieves a nominal efficiency of 96% during full-load operation. Like other FC-302 converters created by Danfoss, the 134U3280 supports various types of inputs and outputs. It employs a powerful set of digital and analog terminals, perfect for processing signals from other electrical modules. When operated alongside a PLC or actuator, this servo drive can be used to dynamically adjust the motor output.
