Description
Schneider Electric ATV71HD11N4
The Schneider Electric ATV71HD11N4 is an efficient variable-speed drive designed for high-power machines. It is part of the Altivar 71 series, made by the French manufacturer Schneider Electric (SE). Notable features include an inbuilt EMC filter and configurable switching frequency, which provide accurate motor control.
The ATV71HD11N4 offers advanced asynchronous and synchronous motor support, ensuring peak performance and energy economy. Its robust construction and extensive application capabilities make it an ideal choice for harsh industrial environments. In demanding applications, the ATV71HD11N4 delivers superior control and economy.
Technical Details:
The ATV71HD11N4 Variable Speed Drive operates with a 3-phase motor at 380 to 480 volts AC. It delivers a motor power of 11 kW, equivalent to 15 hp under the same voltage range. The drive accommodates a maximum motor cable length of 50 meters when shielded. For unshielded cables, the maximum length is 100 meters. The line current for a 480V 3-phase motor is 30 A for 11 kW / 15 hp. For a 380V 3-phase motor, the line current is 36.6 A for 11 kW / 15 hp.
An integrated EMC filter ensures compliance with electromagnetic standards. The assembly style includes a heat sink for effective thermal management. The nominal output current is 21 A at 4 kHz for 460V 3-phase motors, rated 11 kW / 15 hp. For 380V 3-phase motors, the nominal output current is 27.7 A at 4 kHz.
The output frequency ranges from 0.1 to 599 Hz with a nominal switching frequency of 4 kHz. This frequency is adjustable between 1 and 16 kHz. A derating factor applies for switching frequencies between 4 and 16 kHz.
Operational Environment:
The Schneider Electric ATV71HD11N4 Variable Speed Drive is engineered to perform efficiently in various industrial environments. It maintains a noise level of 57.4 dB, conforming to the 86/188/EEC standard, ensuring quiet operation. With a pollution degree of 2 as per EN/IEC 61800-5-1 and an IP20 degree of protection, the drive ensures durability and safety.
The Drive operates efficiently within an ambient air temperature range of -10 to 50°C without derating and can be stored in temperatures ranging from -25 to 70°C. The drive performs optimally at altitudes up to 1000 m without derating and between 1000 to 3000 m with a current derating of 1% per 100 m. This makes it a versatile and reliable solution for demanding industrial applications.
Compliance and Industry Applications:
The drive complies with several important standards, including EN/IEC 61800-5-1, EN61800-3 environment category C3, and EN/IEC 61800-3. This ensures its environmental robustness and electromagnetic compatibility. For specific applications, the Altivar 71 drive is ideal for handling heavy machinery, elevators, pumps, and fans, where precise speed regulation and advanced motor control are crucial.
Frequently Asked Questions:
What is the recommended mounting position for the Schneider Electric ATV71HD11N4 Variable Speed Drive?
The ATV71HD11N4 should be installed vertically with sufficient space for air circulation from bottom to top. This ensures optimal cooling and reliable operation of the drive over its service life.
What is the IP degree of protection for the Schneider Electric ATV71HD11N4 Variable Speed Drive?
The ATV71HD11N4 has IP20 protection, safeguarding it against dust and ensuring safe operation in industrial environments. However, it is not protected against water, so it should be installed in a suitable enclosure if exposure to moisture is possible.
What type of braking torque does the Schneider Electric ATV71HD11N4 Variable Speed Drive support?
The ATV71HD11N4 supports up to 150% braking torque with a braking or hoist resistor. This high braking torque capability makes it suitable for applications requiring rapid deceleration or precise control of motor stopping.
