Product Description

The RD51.1-5N-075-W-V1-FW is a Rexroth Indramat REFUdrive 500 in the voltage frequency control (VFC) series. It is a version 1 drive converter and features a 3-phase RD 42 regenerative power supply module rated at 500 V AC (± 10 %) and 50/60 Hz. The RD51.1-5N-075-W-V1-FW is designed to be used with an inductor and synchronous motor models. Its start-up characteristic features include auto motor adaptation, quick setup, basic parameterization, etc.

At a pulse frequency (PWM) of 4 kHz, the output frequency range of the RD51.1-5N-075-W-V1-FW is 0 - 250 Hz, and its rated current is 108 Amperes. Also, at the same PWM, the peak current of this drive converter is 140 Amperes at 60 seconds, 184 Amperes at 1 second, and 216 Amperes at 0.5 seconds. It has a rated output power of 89 kVA and a peak power of 115 kVA at t = 60 seconds. The environmental class of the RD51.1-5N-075-W-V1-FW is 3K3, as per DIN IEC 721-3-3.

The power rating of the RD51.1-5N-075-W-V1-FW is 75 Watts, and it does not come with an integrated brake chopper. It features a liquid cooling method, and as an additional function, this unit comes with a standby power supply of 24 Volts. This unit has a cooling air requirement of 0.4 m³/s and a power loss of 2.3 kW at 4 kHz PWM frequency. The RD51.1-5N-075-W-V1-FW drive converter is embedded with line reactors and suppression filters to minimize harmonics feedback into the supply line. In addition, the inclusion of filters and reactors ensures that it fulfills EMC directives as per noise emission & immunity. The permissible ambient operating temperature of this unit is within the range of 0 - 40 degrees C. This product can be shipped globally with a one year warranty period from Wake Industrial.
