Product Description:

The Danfoss 178B1390 is a highly efficient and low-voltage drive. With a power rating of 0.55 kW (0.75 hp), this device is well-suited for smaller motor applications where dependable performance is essential. The drive is designed to operate on a single-phase input range of 220 to 240 V AC and can deliver 1.3 kVA power at 230 V. It is compact and fits easily in small areas due to its lightweight of 2.0 kg, but its performance is reliable, and the energy efficiency is 95 %.

This model is designed to handle different levels of current efficiently. It runs at 1x220-240 V and has a normal input power of 8.3A, with the overload current limit of 13.3 A for 60s. Similarly, with a 3x200–240V input, it operates at 4.0 A and can intermittently handle loads of up to 6 A. This low-voltage drive delivers 3.2 A current continually, and up to 5.1 A for 60 seconds, which ensures reliable motor control even in a demanding environment. These characteristics make it ideal for applications that need precise motor speed control.

The Danfoss 178B1390 low voltage drive also features an IP20 enclosure that protects the drive against standard indoor intrusions. With its compact construction, installation is easy and flexible, and its high efficiency helps minimize energy consumption and operating cost. This drive can work with a maximum pre-fuse current of 20 A, so it can be safely incorporated in any electrical system. As part of the VLT 2800 series, this drive is durable, efficient, and user-friendly, making it ideal for industries that need compact and reliable low-voltage motor solutions.
