Product Description:
The 175L1021 Frequency Drive is built by the Danfoss company. The device comes from the VLT 3000 Variable Speed Drives series of the manufacturer for industrial automation systems. It runs on a three-phase power supply of 440/500 volts and is suitable for numerous applications that demand flexible speed and torque regulation.
The 175L1021 frequency drive integrates advanced control methods to deliver consistent motor performance and reduce energy consumption under demanding operating conditions. Its integrated keypad includes a clear data screen and a straightforward menu system for easy parameter configuration and supervision, making it practical in industrial usage. The electrical ratings of this model feature an input supply of 3x440/500 V at 50/60 Hz for durable performance in heavy-duty processes. It provides variable output frequencies ranging from 0 to 400 Hz, which enables precise operation of induction motors at multiple speed ranges. The 175L1021 frequency drive also incorporates built-in voltage and current supervision for promoting safe performance under different loads. The encoder compatibility supports incremental pulse encoders with TTL output that supplies accurate motor feedback in systems where speed and position accuracy are essential. The environmental capabilities are equally significant as the device is designed to function in ambient temperatures up to 45°C without deration.
The 175L1021 frequency drive endures relative humidity between non-condensing 5% and 95% for reliability in damp industrial environments. The construction complies with IEC 68-2-6 vibration standards, protecting components from mechanical strain. Furthermore, it can be mounted up to 1000 meters above sea level without loss of performance, with allowances for reduced ratings at higher elevations. Other notable specifications include adjustable acceleration and deceleration ramp times, programmable current limitation, and torque regulation for efficient motor handling. The integrated protective features shield the system against overload, short-circuits, and ground faults.
