Product Description:

The 175Z0071 Frequency Converter from Danfoss integrates several built in components that eliminate the need for external accessories. It provides programmable inputs and outputs, user friendly configuration and reliable performance in demanding operating conditions.

The 175Z0071 frequency converter includes integral components such as RFI filter, DC coils, screen clamps and serial communication port. These built in features reduce installation space and simplify setup. It uses digital programming techniques for configuring control inputs and outputs. Users can program up to four setups through the control panel or RS485 interface. The rated motor frequency is 50/60 Hz with switching output capability listed as unlimited. The ramp times of the converter range from 0.05 seconds up to 3600 seconds that ensures flexibility for acceleration and deceleration control. The converter supports starting torque of 180 % for 0.5 seconds and acceleration torque is maintained at 100 %. The model’s control card operation is supported at 24 V DC with terminal numbers 12 and 13 assigned for connections. The control card has a maximum load capacity of 200 mA with short circuit protection. The ground terminals are designated as 20 and 39.

The 175Z0071 frequency converter accepts 24 V DC with a tolerance of ± 15 % for external supply. The terminal connections are provided at 35 and 36. The system can handle a maximum of 37 V DC for 10 seconds. The voltage ripple is limited to 2 V DC. The power consumption is rated between 15 W to 50 W with 50 W applied for start-up over 20 milliseconds. The minimum pre fuse requirement is 6 Amps. These specifications ensure stable power handling and safe operation of this frequency converter.
