135U1788

Product Description:

Danfoss 135U1788 is a high-performance drive from the VLT FC 103 Refrigeration Drives series. It is designed for demanding refrigeration and cooling applications. It delivers an output power of 15 kW (20 HP). This drive operates on a three-phase system, which ensures stable power distribution and efficient operation in industrial environments. Three-phase power is critical in heavy-duty applications as it offers consistent torque, reduces energy losses, and supports high-efficiency motor control, making it ideal for refrigeration systems that require uninterrupted performance. With a mains voltage range of 200–240 VAC, the drive is adaptable to various power supply conditions, ensuring smooth functionality across diverse operating environments.

It is engineered with an IP21/Type 1 enclosure rating. The 135U1788 drive is suitable for indoor use where moderate protection is required. While not intended for harsh outdoor conditions, this level of enclosure offers adequate safety for typical refrigeration setups. Additionally, the drive incorporates an RFI (Radio Frequency Interference) Filter Class A2, which minimizes electromagnetic interference, ensuring compliance with industrial standards and reducing signal disturbances to other sensitive equipment. These features make the drive not only efficient but also safe for integration in complex electrical systems where reliability and safety compliance are paramount.

Although the Danfoss 135U1788 does not include a brake chopper, it ensures energy efficiency and operational stability, which are essential for most refrigeration processes. The absence of a brake chopper means it is suitable for applications that do not require dynamic braking, thereby simplifying the system design and lowering costs. Additionally, the inclusion of a fuse for protection, along with a frame size of B2 and a net weight of 27.82 kg, ensures easy handling and installation.
