Product Description:
The 178F2244 drive is developed by Danfoss with product code 5052PT7CN1EBR0DLF10A00C1. It features a high-efficiency rating of 96% at rated load and its power loss during normal overload (110%) is 1571 W, while under high overload (160%) its power loss is recorded as 1275 W. The drive is presented in a NEMA 1/NEMA 12 enclosure for protection against dust and water.
The 178F2244 drive’s output voltage can vary from 0 to 100% of the supply voltage, while the output frequency can range from 0 - 132 Hz. It provides high torque capabilities with a starting value of 160% and its acceleration torque is maintained at 100% to handle high load conditions with consistent performance. This unit needs an input voltage in the range of 380 - 500 V (three-phase) and supports a supply frequency of 50/60 Hz. Its rated current is 90 A at 380 - 440 V, along with a peak value of 99 A for 60 sec in normal overload conditions of 110% torque, while in overload scenario of 160% torque, the rated current draw is measured as 73 A and the peak current for a short burst is recorded as 116.8 A. Its input current value at 380 V is 89 A and it reduces to 77 A at 460 V.
The 178F2244 drive weighs 42 kg for the IP20 EB version and 56 kg for the IP54 version. It offers 60 HP of shaft power at normal load conditions and 50 HP in high overload scenario. The 178F2244 drive’s cooling system requires sufficient airflow space and its maximum cable cross-section for motor and power connections is 16 mm². Its supports fuse rating of 125 A at the input.
Frequently Asked Questions about 178F2244:
Q: How does the 160% starting torque in the 5052PT7CN1EBR0DLF10A00C1 drive aid motor startup under load?
A: The 160% starting torque allows the motor to overcome static friction and heavy load inertia without slipping or stalling. It ensures smooth startup in applications like crushers or conveyors where load is maximal at rest.
Q: What purpose does the wide input voltage range (380-500 V) serve in product code 5052PT7CN1EBR0DLF10A00C1?
A: It allows the drive to be deployed across different voltage supply standards without voltage switching hardware. This flexibility makes it suitable for international installations or fluctuating grid conditions.
Q: How does enclosure type (NEMA 1/NEMA 12) affect the 178F2244 drive’s deployment?
A: NEMA 1 provides protection against light dust and incidental contact; NEMA 12 adds protection against non-corrosive dust, oil, and dripping water. This allows use in indoor factories or semi-enclosed outdoor control rooms.
Q: Why is the variable output frequency up to 132 Hz beneficial in the 5052PT7CN1EBR0DLF10A00C1 drive?
A: Frequencies above standard 50/60 Hz permit higher motor speeds where needed for variable process demands. It enables equipment like fans or centrifugal pumps to deliver more output without overgearing.
Q: How does maintaining 1571 W loss at 110% overload affect efficiency in the 178F2244 drive?
A: The losses increase under overload, the 178F2244 still maintains high overall efficiency (~96%), meaning excess energy waste is minimized. It ensures thermal stability and long life even under mild overloads.
