Product Description

The Bosch RD52.1-4B-018-L-V1-G3-T1-FW is a Rexroth RD 500 series drive control device. It features field-oriented vector control. The drive is cooled by forcing air over the heated components. Power section on the drive are cooled at the rear. Therefore forced air cooling can be implemented with a higher degree of protection. Nominal connection voltage for the RD52.1-4B-018-L-V1-G3-T1-FW is three phase 380 to 480 Volts AC with ±10% allowed variance. Rated power draw of the drive system is 18.5 kilowatts. The drive also supports 24 Volts standby power. The drive firmware needs to be ordered separately. AC converter on the drive comes with a brake chopper and mains filter. The rated motor output at 8 kilohertz pulse frequency is 15 kilowatts. The output frequency range is 0 to 500 Hertz. The rated output current is 30 Amps.

The peak current ratings for 60 seconds, 1 second and 0.5 seconds are 39 Amps, 51 Amps and 60 Amps respectively. The output power for 60 seconds is 26 kVA. Environmental class of the RD52.1-4B-018-L-V1-G3-T1-FW is 3K3 according to DIN IEC 72103. The working temperature range is 0 to 40 degrees Celsius. For proper cooling the RD52.1-4B-018-L-V1-G3-T1-FW requires 0.05 m³ per second of air flow. The power loss rating for an RD52.1-4B-018-L-V1-G3-T1-FW drive system operating under load conditions is 0.63 kilowatts. Protection class with connected plug is IP 20 as per EN 60529. Weight of the converter on the drive is 11.3 kilograms. An integrated operator panel can be used to commission the RD52.1-4B-018-L-V1-G3-T1-FW drive. A programming PC with the RDwin software can also be used for drive commissioning. Only trained and qualified personnel should be allowed to install and operate this three phase drive system. This product can be shipped globally with a one year warranty period from Wake Industrial.
