Product Description:
The HNL05.1R-0125-N0152-N-A5-NNNN is an HNL series mains choke designed by Bosch Indramat for industrial servo drive applications. It is suitable for food processing, packaging and conveyor systems due to its reduced current harmonics in the drive system. This choke protects connected equipment from voltage spikes and circuit feedback.
The HNL05.1R-0125-N0152-N-A5-NNNN choke features a nominal inductance of 125 ?H and its rated input current is 152 A. It supports a supply voltage range of 525 to 690 V AC with a voltage tolerance of +15 % and -10 %. This choke is built for three-phase operation and it works with an efficiency of 95% in Rexroth IndraDrive ML systems. Its design ensures consistent performance under continuous industrial loads as it maintains thermal stability using natural convection cooling and does not require fan or forced air system. The heat loss of the unit is approx. 1800 W and it features a strong steel mounting frame. The HNL05.1R choke has three vertical laminated iron-core inductors which are securely enclosed within an open frame structure for heat dissipation. It has a power terminal block for wiring that includes heavy-duty terminals for safe electrical connections. The HNL05.1R choke is rated with an IP00 protection class and must be installed with base mounting configuration in an external cabinet with minimum requirement of IP56 protection.
The HNL05.1R-0125-N0152-N-A5-NNNN main choke has a height of 374 mm, width 306 mm and depth of 208 mm. This choke can be used in various environmental settings due to its ambient conditions of up to 318.15 K temperature and 0.95 relative humidity. The HNL05.1R choke should only be installed by qualified industrial personnel and it can operate without maintenance for over five years.
Frequently Asked Questions about HNL05.1R-0125-N0152-N-A5-NNNN:
Q: What is the role of the thermal stability feature in the HNL05.1R-0125-N0152-N-A5-NNNN choke?
A: The thermal stability ensures the choke can handle continuous industrial loads without overheating. This feature helps maintain reliable performance, even in environments with fluctuating temperatures.
Q: Why does the HNL05.1R-0125-N0152-N-A5-NNNN choke not require forced air cooling?
A: Its design utilizes natural convection cooling, which is energy-efficient and reliable for long-term operation. This eliminates the need for additional cooling systems, reducing overall maintenance costs.
Q: How does the IP00 protection class affect the HNL05.1R choke?
A: The IP00 protection class indicates that the choke is not protected against dust or moisture, requiring it to be housed in an external cabinet with at least IP56 protection. This ensures safety and protection in harsh industrial settings.
Q: Why is the inductance value of 125 uH important in the HNL05.1R choke?
A: A 125 uH inductance value helps minimize current harmonics, which is crucial for maintaining smooth operation of industrial drives. It contributes to energy efficiency and system stability.
Q: What are the benefits of using the HNL05.1R-0125-N0152-N-A5-NNNN in servo drive applications?
A: The choke's efficient operation at 95% ensures minimal power loss, and its robustness under continuous loads makes it ideal for demanding industrial applications like Rexroth IndraDrive ML systems. This improves the overall efficiency of the drive system.
