Product Description:
The Danfoss 175H9077 VLT 3000 Variable Speed Drive is developed for dependable automation tasks. The drive provides efficient regulation of motor performance. The design supports challenging operation in industrial automation systems. It maintains stable control during continuous duty. The construction provides suitability for demanding environments that requires stable drive performance.
The 175H9077 speed drive delivers an output current of 7.3 A. The current level supports mid-range motors without risk of overload under normal conditions. The typical shaft output is 3 kW. The rating matches motors used in conveyors, pumps and ventilation systems. The supply voltage supports three-phase 380, 400 or 415 V ±10%. The supported frequency by the drive is 50 or 60 Hz. The dual frequency rating allows integration in both European and international installations. The power factor operates at 0.9 to 1.0 Cos. The high factor minimizes reactive power losses and improves grid efficiency. The drive efficiency is 0.96 at full load which reduces system energy waste while sustaining stable torque output. The switching limit is two times per minute. The restriction provides controlled activation without thermal stress on power components.
The 175H9077 variable speed drive specifies a maximum cable cross section of 12 AWG. The cable size provides secure current transfer to connected motors without excessive heating. The drive requires prefuses rated at 16 A. The fuse specification provides protection against short circuits and overloads within the supply circuit. The cooling system is air-cooled which prevents temperature rise during extended operation. The enclosure supports constant thermal management under standard ambient conditions. The dimensions of the drive facilitate panel integration and simplifies installation in control cabinets where space constraints apply. The Danfoss VLT 3000 speed drive complies with industrial operating requirements for longevity and functional safety.
