Product Description:
The Danfoss 176F7308 Micro Drive is a versatile frequency drive. It is designed for reliable and efficient control in various industrial applications. With its compact design and robust features, it offers excellent motor control. It is from the family of VLT Adjustable Micro Drive.
The 176F7308 unit is suited for applications that require 1 horsepower (0.75 kW) of typical shaft output. The drive requires an input power of 200-240 V, single-phase, at 50/60 Hz, with a maximum input current of 6.3 A. It allows for a maximum cable size of 14 AWG (2 mm²) for input power and motor connections. The Drive contains a 25 A pre-fuse which provides additional protection during operation. The drive has a shielded chassis (IP20) which ensures longevity in harsh conditions. With a weight of 2.25 pounds and a vibration test tolerance of 1.0 g (under 20 Hz) and 0.6 g (20-50 Hz) it provides stability and dependability. The drive's control inputs consist of six programmable digital inputs, one analog input (0-10 VDC or 4-20 mA), one relay output and one programmable analog output (0-10 VDC). The drive supports ramp times of 0.1 to 600 seconds and includes overvoltage stall prevention for enhanced protection. Its speed control range is 1:20 synchronous speed, allowing for accurate motor management. The drive assures speed accuracy, with a maximum error of 2% below 1800 rpm and 0.5% over 1800 rpm.
The Danfoss 176F7308 is built to handle temperatures up to 50°C and can be stored or transported within a temperature range of -20°C to +60°C. The drive provides high control precision, with a frequency range of 0.1-400 Hz and a resolution of ±0.1 Hz. With a strong beginning torque (150% for 1 minute and 200% for 5 seconds), the drive can withstand high load circumstances. It also provides overload torque protection at 150% for one minute. It is also designed to handle motor cable lengths of up to 50 meters for 240V and 50 meters for 480V units, ensuring flexibility in installation.
