178U2557

Product Description:

Danfoss 178U2557 is specifically engineered for refrigeration applications. It is designed to support a 15 HP motor. It operates on a 208 VAC input voltage and a three-phase power supply, making it ideal for industrial environments that require precise motor control and energy efficiency. The drive features a NEMA 1 (UL Type 1) enclosure, ensuring protection against dust and minimal exposure to environmental factors. Its operational frequency range of 0-60 Hz allows for smooth motor speed adjustments, enhancing refrigeration system performance and reducing energy consumption.

Among the most important protection and safety features of this drive is that it has main and drive fusing. Fuses are important to prevent electrical faults in the drive and motor, like overloading or short circuits. These fuses keep the equipment safe by identifying the fault quickly while maintaining system reliability and further reducing downtimes in the entire refrigeration process. The drive also includes an output dV/dt filter, which helps control voltage peaks and regulate the rate of change. This not only prevents excessive wear of the motor insulation but also increases the lifetime of the motor and maintains stable performance, particularly where long cables are used and cause extra stress.

The Danfoss 178U2557 also has a Type 2 RFI filter installed to improve electromagnetic compatibility. It uses only one motor, which makes the installation and use in single-purpose refrigeration systems more straightforward. A graphical display also makes this drive more user-friendly, with easy-to-comprehend real-time information and diagnostics. This drive has a non-condensing humidity tolerance of 95 percent and an ambient drive operating temperature of a maximum of 45 degrees Celsius, so it is ideal for harsh and tough environments like refrigeration systems where efficient cooling is required.
