Product Description

The RD51.2-4B-015-P-A2-FW is a standard frequency converter model manufactured by Bosch Rexroth Indramat. It has modular software and hardware that guarantees optimal compatibility with specific drive requirements. In addition, the RD51.2-4B-015-P-A2-FW boasts a freely switchable function block for simple programmable logic control requirements.  This model leverages parameter identification for automatic motor adjustment via the powerful RDwin software tool. It belongs to the VFC converter series, and its supply voltage is rated at 380 – 480 Volts (±10%).

The RD51.2-4B-015-P-A2-FW comes with an integrated braking resistor, and its power code is 15 – which translates to an output power of 15 kW. This frequency converter monitors the external brake resistor by calculating a thermal model with the current braking power using its firmware. If the thermal model's limit values are exceeded, the frequency converter shuts down with a "braking resistor" error to protect the braking resistor from overloading. The RD51.2-4B-015-P-A2-FW utilizes a heat exchanger plate for heat dissipation and temperature control. An additional function of this frequency converter includes a 24 Volts start inhibitor and stand-by power supply for devices within its output power range.

The rated current of this unit at its mains supply voltage is 30 Amperes. As per time-based peak current variations, the RD51.2-4B-015-P-A2-FW attains a peak current of 39 Amperes for 60 seconds, 51 Amperes for 1 second, and 60 Amperes for 0.5 seconds. The heat discharge plate of this unit weighs 12 kg. At nominal operating conditions, the efficiency of RD51.2 converters range between 0.97 to 0.98, depending on the output power range. The RD51.2-4B-015-P-A2-FW is IP 20 protected as per EN 60529. Additionally, its nominal ambient operating temperature range is between 0 – 40 degrees C. This product can be shipped globally with a one year warranty period from Wake Industrial.
