Product Description:

The 131B7535 is a mid-range frequency converter from Danfoss's FC series rated for 4.0 kW. It is engineered to ensure optimal operation in HVAC applications that require moderate power output. Its straightforward operation enhances usability, ensuring simplified system management without requiring technical expertise. The drive delivers 6.93 kVA apparent power with optimized electrical characteristics for typical HVAC applications. It excels in medium-sized commercial buildings, office complexes and retail facilities where consistent climate control and operational efficiency directly impact occupant comfort and energy costs.

The 131B7535’s power conversion efficiency is demonstrated through its 124-watt power loss during standard operation. This indicates that the drive prevents excessive power loss, enhancing energy usage. This efficiency is also crucial in minimizing heat generation and reducing cooling requirements within HVAC control environments. The drive offers a 10 A continuous current rating which allows it to efficiently handle 5 HP motors. Its power handling capacity enables adaptable operation under varying loads, ensuring dependable performance under varying load scenarios. The drive’s three-phase AC input of 380 to 480 V accommodates standard international commercial electrical systems, making it easy to integrate into diverse HVAC systems. This unit is designed to filter electrical noise during operation, making it a good choice for systems where sensitive components may be impacted by excessive EMI emissions.

This drive model features the most current version of Danfoss software, providing HVAC control algorithms and energy optimization features for enhanced efficiency. The drive should be installed in clean environments since its IP20 sealing does not prevent dust or water ingress. Operation conditions should be within permissible industrial limits and not above 50°C for optimal reliability. The drive has an A2 frame size that is designed to offer practical mounting dimensions for standard commercial HVAC control panels.
