R911271401
The Bosch Rexroth Indramat R911271401 (KVR01.3-30-3/S380) is a high-quality auxiliary module, part of the company's sophisticated AC drive system that consists of both drives and a power supply module. This supply module holds the capacity to interface with multiple drives simultaneously, providing DC power supply and control voltage to servo drive modules as well as the main power supply. Additionally, it is equipped with superior monitoring capabilities and offers supply for drive electronics via a signal voltage bus.
Designed to operate on a frequency range of 50Hz to 60Hz, the R911271401 (KVR01.3-30-3/S380) features a maximum peak power of 90kW in its DC link circuit and supports a bleeder power of 40kW. A device for rapid deceleration, the bleeder is utilized during emergency shutdowns. While operating at full capacity, the module exhibits an internal power dissipation of 170W. It weighs 31kg, and a 4.2kg fan is incorporated for efficient cooling. This supply module also has a rectifier that can convert three-phase AC voltage from the main power supply into a regulated DC voltage, which can also store regenerated energy from motor braking in the bleeder resistor.
