Product Description:

The 175Z7029 is a three-phase HVAC drive intended for use in motion-controlled systems that require regulated speed and torque. This unit from the Danfoss range of energy-efficient VLT models is suited for commercial building systems that need a reliable drive that can handle moderate overloads. This drive is built with a focus on thermal management and electrical reliability, which are vital for continuous-duty HVAC operations in commercial environments. It operates with reduced power loss which is essential in keeping cooling requirements minimal while also ensuring efficient usage of power.

The drive's dependable performance is facilitated by impressive specifications that include a 24 A rated output in nominal conditions. When the drive needs to handle unexpected high loads it can provide a 110% overload capability for one minute. This feature helps meet increase load demands during scenarios such as motor starting and other temporary load increases common in HVAC equipment. The drive accepts a 3 x 400V AC input, which fits standard European commercial electrical systems. Its output frequency can ranges from 0-120 Hz, depending on application needs. This allows for ample versatility in speed performance, enabling the drive to adjust to real-time requirements as needed. This specific frequency range also boosts drive efficiency and lowers electrical stress on connected motors, enhancing durability and overall system reliability.

The drive operates on standard inputs of 50/60 Hz frequencies, ensuring global compatibility with commercial building electrical systems. The design philosophy of the VLT 6000 series prioritizes simplicity and reliability, avoiding advanced features that aren't necessary in basic HVAC applications. The drive’s thermal design supports continuous operation found in commercial buildings, where motors often run for long periods under varying loads.
