Product Description

Bosch Rexroth manufactures the RD51.1-4N-055-L-D1-FW, and it functions as a high-performance 3-phase drive converter. Its primary design function is to be used with inductor/synchronous motors, and it can easily be adapted to specific drive applications. As per its line supply voltage rating and PWM frequency (4 kHz), the rated current of this drive converter is 99 Amperes. The RD51.1-4N-055-L-D1-FW can also function at 8 kHz and 12 kHz with varying operational specifications.  

The proper relative humidity of the RD51.1-4N-055-L-D1-FW must be maintained below 90% per time. Its ambient temperature range is 0 – 40 degrees C. Also, the air drawn into this unit must be devoid of electrically conductive or aggressive gases that may negatively impact its functionalities.  The RD51.1-4N-055-L-D1-FW dissipates heat during operation, and for this reason, it must be sufficiently distanced from heat-sensitive components and equipment. Furthermore, the storage space of this unit must be dry and clean, with ambient temperatures maintained at -25 degrees C to 70 degrees C. If temperatures fluctuations shoot over 20K hourly, the RD51.1-4N-055-L-D1-FW must not be utilized under such a condition.

The design of the RD51.1-4N-055-L-D1-FW drive converter includes an aluminium-Elko direct current (DC) link capacitors, which can be stored under zero voltage conditions for about 2 years. If this drive converter is kept in storage for more than the stipulated period, the link capacitors must be reformed before commissioning. During the manufacturing of the RD51.1-4N-055-L-D1-FW, Rexroth emphasizes simple commissioning, user-friendliness, operator panel control, and software compatibility (with the REFUwin software package). The rating plate on this unit contains its type code, line voltage, line frequency, output voltage, output frequency, rated/peak current, and rated current for impulse fuses. This product can be shipped globally with a one year warranty period from Wake Industrial.
