Product Description

The Bosch Rexroth RD52.1-4N-007-L-V1-FW is a RD52 series digital drive controller. The controller is designed for commercial and industrial applications. Radio interference filters on the controller prevent feedback of harmonics to the line supply. RD52 series drives support AC or DC input. The inverter on the RD52.1-4N-007-L-V1-FW accepts DC input ranging from 530 to 670 Volts DC. The converter does not include a built-in brake chopper. Output power delivered by the controller varies with pulse frequency. The rated motor output at 4 kilohertz pulse frequency is 7.5 kilowatts. The rated motor output at 4 kilohertz pulse frequency is 5.5 kilowatts. The controller is designed for forced air cooling. This cooling method uses a blower or cooling fan to increase airflow across the drive housing. The temperature of air surrounding the drive should be between 0 and 40 degrees Celsius.

Protection class of the RD52.1-4N-007-L-V1-FW is IP20. This means that operators who wish to use the controller outdoors must mount it inside a control cabinet. Even for indoor use, drive mounting inside a cabinet will help to protect the drive from dust and other contaminants. RD52 drives support a range of additional functions. The RD52.1-4N-007-L-V1-FW supports one additional function: 24 Volts standby power. With this feature operators can parameterize the drive even when the main DC input is not available. Another advantage of this feature is that the filed buses can continue to operate in the absence of input power. However it must be noted that the 24 Volts standby power feature does require an external 24 Volts DC supply. The shipping weight of the drive is 6.5 kilograms. Size class of the drive unit is A.
