Product Description

Components like inverters for DC supply, converters, and power supply modules in regenerative feedback and normal power supply versions comprise the RD 500 drive system by Indramat Refu. The drive system is a modular universal three-phase system that allows customization to suit specific tasks. The converters of the RD 51 series in this drive system are used in centrifuges, pumps, and moving gear.

The RD51.1-4B-005-L-V1-FW is a converter model in Indramat Refu’s RD 500 drive system, which works with voltage frequency control. This means that the set value determines the output frequency of the converter, and its output voltage is adjusted to correspond to this frequency. It utilizes a nominal connecting voltage between 380V and 480V with a tolerance of ±10% and has a rated power of 5kW. This model is equipped with an integrated brake chopper whose continuous power rating is 2.8kW. It is a converter of Size Class A and is designed for cooling by the forced-air cooling mechanism.

Fast–switching semiconductors are used in the construction of the RD51.1-4B-005-L-V1-FW, ensuring power loss reduction. The converter meets the demands of the EMC directive on noise immunity and noise emission. According to EN 60529, it is a product of the IP 20 protection category, indicating that it is touch-proof and impermeable by solid extrinsic objects over 12mm. With its standby 24V DC power supply, some operations can be carried out on the converter without any connected line supply voltage. These include the reading, writing into, and parameterization of data sets and the uninterrupted operation of field buses. It has a removable control panel and is compatible with the Indramat Refu RDwin software program.
