Product Description:

The VLT 6000 HVAC Drive 175Z7032 is developed by Danfoss company. It is a three-phase variable frequency drive engineered for industrial automation settings. It belongs to the trusted VLT series that provides energy efficiency and ensures reliable motor control in variable speed applications.

This 175Z7032 frequency drive accepts a three-phase input voltage range of 380 to 460 VAC. The operating frequency of the drive rates at 50/60 Hz. This frequency drive draws an input current of 44 A. The output voltage matches the input phase and delivers 0 to Uin at a frequency range of 0–1000 Hz. The maximum output current of the drive is 44 A. The rated output power capacity is 31.6 kVA. This makes it suitable for controlling large HVAC motors and air handling units. The 175Z7032 frequency drive is housed in an IP20-rated open chassis. The front panel of the LCP is IP65 rated to provide high protection in dusty or lightly wet environments. It is designed for ambient temperatures up to 40°C without derating. However, the thermal derating is applied up to 45°C. The installation of the drive is supported up to 1000 meters elevation under standard ratings, and up to 2000 meters with derating. Additional features include DC braking terminals, relay outputs, and a combination of analog and digital I/O interfaces.

The humidity operation of the 175Z7032 frequency drive is rated at 5% to 95% non-condensing. This allows reliable operation in humid HVAC equipment rooms. The vibration resistance complies with IEC 60068-2-6. It withstands 1.0 mm amplitude from 2–9 Hz and 1.0 g acceleration from 9–200 Hz. This provides stable operation in environments subject to mechanical stress. The cooling system incorporates a heatsink and an internal fan assembly.
