Product Description:

The 175Z7473 is a VLT 6000 series frequency converter. It is used to control speed of pump and fans in large-scale HVAC applications. Its housing complies with IP54 protection rating. This is a rating from IEC’s Ingress Protection (IP) code, which defines how well an enclosure provides protection against dust and water. This type of enclosure does not entirely prevent dust from entering, but enough dust is blocked to prevent damage or malfunction. Regarding liquids, this type of enclosure is protected against water splashes from any direction, but does not protect against strong jets or immersion. At maximum output load, the specified power loss of the 175Z7473 converter is 655 Watts. Shipping weight of this unit is 42 kilograms. Its rated efficiency at the rated frequency is 0.96.

The recommend power cable size for the AC mains connection is 6 AWG. With an input range of 380 to 460 Volts, the converter’s input current is 37.5 Amps at 380 Volts and 34 Amps at 460 Volts. AC output of the 175Z7473 is variable, and it can supply 0.1 to 1000 Hertz output frequency and 0 to Vin output voltage. The output current is 37.5 Amps at 380 to 440 Volts and 41.3 Amps at 441 to 460 Volts. The peak output current is 41.3 Amps at 380 to 440 Volts and 37.4 Amps at 441 to 460 Volts. These peak current values are only valid for time durations not exceeding 60 seconds. Typical value of the output the motor is 18.5 kilowatts (25 Horsepower). For this IP54 unit, the motor cable size is 6 AWG. Ideal ambient temperatures for the unit are below 40 ⁰C.
