Product Description

The RD51.2-4B-005-P-A2-FW is a standard Bosch Rexroth Indramat frequency converter. The software and hardware are modular and ensure excellent compatibility with individual driving needs. The RD51.2-4B-005-P-A2-FW also features a function block that is freely switchable for simple PLC requirements. This model uses parameter identification with the sophisticated RDwin software application for automatic motor adjustment. It belongs to the VFC series and has a voltage of 380 – 480 Volts (±10 percent).

The RD51.2-4B-005-P-A2-FW is supplied with an inbuilt braking resistor with a 15-kilowatt output power rating. This frequency converter checks the external brake resistance by calculating a thermal model using its firmware. If the limit values of the thermal model are exceeded, the frequency converter shuts down to prevent the braking resistance from overload and displaying a "braking resistor" error. RD51.2-4B-005-P-A2-FW uses a plate-type heat exchanger to regulate temperature. This frequency converter also contains a starting inhibitor and 24 Volts standby power supply for devices in its output power range.

This unit's rated current at its mains supply voltage is 30 Amperes. The RD51.2-4B-005-P-A2-FW reaches a peak current of 39 A for 60 s, 51 A for 1 s, and 60 A for 0.5 s, according to time-based peak current variations. This unit's heat discharge plate weighs 12 kg. The efficiency of RD51.2 converters ranges from 97% to 98% at nominal operating conditions. According to EN 60529. the RD51.2-4B-005-P-A2-FW is IP 20 protected. It also has a nominal ambient operating temperature range of 0 to 40 degrees Celsius. This unit is suitable for use in areas where the contamination level is 2. Also, its radio interference/noise immunity is A1, as per EN 55011/ EN 61800-3. This product can be shipped globally with a one year warranty period from Wake Industrial
