Product Description:

The 175Z0305 drive is from the VLT 5000 Frequency Converters series. It has high-performance capabilities for industrial applications. It is engineered for usage in tough conditions, with effective torque control and dependable protection. It is manufactured by Danfoss.

The Danfoss 175Z0305 is designed to provide great efficiency and performance. It has a large supply voltage range of 380-500 V and a frequency range of 48-62 Hz ±1%. The output voltage can be changed between 0 and 100% of the source voltage. The drive has an output frequency range of 0-132 Hz and can go up to 1000 Hz depending on the unit configuration. For one minute, the starting torque is 160%, followed by 100% acceleration and 160% overload torque. It is outfitted with a VVCplus control card for accurate motor control. The device includes a detachable control panel with a four-line alphanumeric display. It also supports communication protocols like Profibus, Modbus and DeviceNet. There is also a SyncPos programmable controller option for added flexibility. The IP20 variant weighs 10.5 kg and is suited for small wall mounting or control cabinet installation. The drive meets EMC standards for emissions and immunity to ensure safe use in electrical situations.

The 175Z0305 provides good protection for motor connections including short-circuit and earth fault. It also includes over-temperature protection with an automatic cutout at 90°C for IP20 and 80°C for IP54 variants. The device is designed with an IP20 (Bookstyle) enclosure; however, it is also available in IP00 and Nema1 variants to meet various installation needs. At rated load, it has an efficiency of 96%. This type is appropriate for operation without derating up to 1000 meters above sea level with greater altitudes requiring additional considerations.
