Product Description:
The Danfoss 178B7281 is a high-efficiency cooling drive from the AKD Adaptive Cooling Drives series. It is designed for refrigeration and HVAC applications where keeping the right temperatures is very important. This drive has a maximum output power of 18.5 kW and an output frequency range of 0 to 1000 Hz, which makes it flexible and easy to manage for both small and big cooling systems. The 178B7281 is designed to be flexible and available with two different housing options: IP20 and IP54.
The IP20 version is best for protected interior installations like control rooms and equipment cabinets. The IP54 version, on the other hand, is strong enough for tougher situations like walk-in coolers, freezer rooms, and outdoor condensing units where moisture and dust are prevalent. This adaptability makes sure that it works well in a broad variety of commercial and industrial situations. The adaptive cooling technology is a big aspect of the AKD series, especially the 178B7281. This drive, on the other hand, constantly changes the motor output based on the current cooling demands and the environment. Traditional drives only work at set speeds. This adaptive method not only keeps the temperature exactly where it needs to be, but it also saves energy by automatically lowering output when demand goes down. This saves a lot of energy and makes the equipment last longer.
The 178B7281 can work with a wide variety of voltages, from conventional 200–240V for smaller units to 380–480V for mid-range systems. Higher-power variants can even work with voltages up to 525–690V. This wide range of voltage compatibility makes it easy to add to many different facility power systems, which helps keep installation costs low and makes sure it fits well with the infrastructure that is already there.
