Product Description

The RD52.1-4B-022-L-FV-FW is Bosch Rexroth's state-of-the-art 3-phase current drive converter system. It provides several universally acceptable applications, including a combination with synchronous and induction motor models. The RD52.1-4B-022-L-FV-FW works on a frequency-controlled mechanism; in other words, the set value determines the converter's output frequency. Its output voltage is also proportionally adjusted to the frequency. Machine tools, foodstuff and packing machines, conveyor and hoist technology, handling systems, and chemical process technology are all common uses for the RD52.1-4B-022-L-FV-FW. It is not suitable for use in submerged situations or under extreme temperatures. This model boasts a removable user panel with a parameter copy function.

The RD52.1-4B-022-L-FV-FW is a converter-type drive with a nominal 3-phase connection voltage of 380–480 Volts ±10 %. It has a built-in chopper brake system and a nominal power rating of 22 kW (4 kHz). This unit's cooling mode is achieved with forced convection, and it features feedback of current filter and a 24-V standby power as additional functions. Its firmware must be ordered as a separate sub-item.

The RD52.1-4B-022-L-FV-FW is class A equipment. It has an output current of 43 Amperes at a pulse frequency (PWM) of 4 kHz. At 8 kHz, the rated motor output of this unit is 18.5 kW, and its rated current has a value of 35 A. Its size class is C, and by design, it is rated IP 20. This converter features a 4-line graphical display and expandable technology functions. According to the EMC Standard for electrically powered drives, the design of the RD52.1-4B-022-L-FV-FW completely fulfills the Electromagnetic Compatibility Directive regarding noise emission/immunity the EMC Standard for electrically powered drives (EN 61800-3, EN 55011 Class A (IEC 1800-3). This product can be shipped globally with a one year warranty period from Wake Industrial.
