Product Description:

The Danfoss 134F2974 is a frequency converter designed for industrial automation tasks that need specialized control of motion with advanced mains configuration options. It provides a dependable 1.5 kW output, allowing use in applications with small to medium-duty industrial motors that require precise speed regulation and specialized power sharing capabilities. This drive is tailored for industrial applications that demand load sharing with built-in braking functionality and improved EMC performance. Its power specs include a three-phase 380 to 480VAC operating range with a T4 temperature rating. This ensures robust operation across standard industrial electrical systems while keeping installation requirements manageable.

The electrical design of the drive includes a load sharing mains option that allows multiple drives to share common power sources while still maintaining individual motor control. This feature helps reduce the need for extensive electrical infrastructure and supports flexible system designs where multiple motors need coordinated control from shared power supplies. The drive comes with a brake chopper, simplifying system design and enabling quick deceleration control, which is crucial in material handling and positioning tasks. The RFI Class A2 electromagnetic classification allows the drive to operate reliably alongside sensitive industrial equipment.

Constructed with a J1O frame and coated PCB protection, the 134F2974 drive offers a compact installation footprint while delivering strong performance in industrial settings. The coated circuit boards protect against damage from contaminants, extending the lifespan of components and reducing maintenance needs. The drive’s standard control card with BX configuration provides comprehensive motor control functionality while keeping system implementation cost-effective for applications that require reliable variable speed control. This unit has a modest mass of just 2.5 kg so handling and installation are hassle-free. It features an IP20 chassis that is designed for panel mounting.
