Product Description:
The Frequency Converter 175Z0126 by Danfoss has an IP20 protection rating that prevents solid particles from entering the internal components during normal mounting. For storage and transport, it can withstand a relative humidity of 93%, tested and certified according to IEC 68-2-3 specifications.
The efficiency of the 175Z0126 frequency converter under full load is 96%, which means less power is consumed when it operates continuously. It also features two user-programmable relay outputs, which can be programmed for user-specific application needs like system signals or alarms. In addition, it offers two analog outputs with 8-bit resolution, which allow for accurate representation of analog signals for monitoring and automation systems. This converter is appropriate for mounting at altitudes up to 1000 meters above sea level, with stable operation without derating at this altitude. This converter attains a displacement power factor higher than 0.98, maintaining operation near unity and reducing unwanted reactive power flow in electrical networks. When it operates under heavy load, its power loss is not more than 67 W, which reduces wastage of energy and heating up.
The 175Z0126 frequency converter provides a wide output frequency range from 0 Hz to 1000 Hz for flexible control of systems connected. This frequency is supported by ±0.003 Hz resolution, which ensures precise control of frequency. The input frequency of this converter supports 50 Hz and 60 Hz sources to be compatible with various regional power standards and electrical infrastructures. This frequency converter has a maximum short-circuit withstand capability of 100000 A to show strong electrical endurance and handle sudden fault currents safely. To provide reliable input performance, it has a maximum input error of as low as 1% full scale, ensuring reliable accuracy in all applications.
