Product Description:
The 131H3278 is a variable speed drive in the VLT FC 301 Automation Drive family, used to offer reliable and efficient control of the motor in smaller-scale automation applications.
Known by the type code PK55, this model is appropriate for low-power motor-driven systems and compact machines because of its 0.75 HP (0.55 kW) output power. It runs on a three-phase supply of 200-240 V AC and provides constant performance over typical industrial voltage levels. The drive is capable of providing a constant output current of 3.5 A and reliable performance. It can also cope with an intermittent overload current of up to 5.6 A within the same voltage range, making it suitable for applications that require stable operation as well as occasional higher current demands. On the input end, it consumes a steady current of 3.2 A and will have a maximum intermittent current of 5.12 A. This design enables the unit to absorb the peak loads that may occur temporarily, and this guarantees the unit operates under changing conditions effectively.
The drive provides 1.26 kVA apparent power rating at 208 V for efficient operation at lower voltage. At 230 V, the rating is increased to 1.39 kVA, confirming its use in compact machinery of the small power range. At maximum load, the 131H3278's power loss is only 42 W, demonstrating its high efficiency of 0.95 at rated current. The unit is rated to carry 160 percent of the maximum current rating for one minute every ten minutes under overload circumstances, which is a strong margin to cover demanding uses. It complies with international safety and electromagnetic compatibility requirements since it has A1/A2 (IEC/UL) protection ratings.
