Product Description

The KVR 1.2-15-3 power supply module from Bosch Rexroth belongs to the KVR series of such modules. This module is used with modular AC drives from the same manufacturer. The product along with a motor and an AC drive forms a modular AC drive system. The unit is capable of fulfilling the various power requirements of multiple drives. It has a continuous mechanical power of 24kW. The device is integrated with a power rectifier. This rectifier transforms the AC line voltage to the DC bus voltage that is needed for providing the drives with the required power. The module has an S2 reset button on its front panel.

The power supply module can store around 40W for every mF of auxiliary capacitance when it features a DC regulated bus voltage. The heatsink blower for the device has a connection power rating of 70VA. The drives receive the signal voltage from the power supply through a wire-ribbon cable. This cable is also used for all other communication purposes. The product features a series code of 1 and a version code of 2. The device has a size of 390mm x 215mm. The unit must be stored at a temperature ranging between -30°C and 85°C.

The line voltage of the module varies from 3 x 380VAC to 460VAC. There is a tolerance limit of +/-10% for this line voltage. The wire-ribbon cable must be connected to the X1 connector of this device. The front panel encompasses the list of fault diagnosis codes and their meanings. The Bb ready-state contact shuts off the power supply to the drive as soon as there is trouble. The LED display indicates a two-digit diagnosis code. The power supply module comes with a one-year warranty and can be sent to the address of your choice.
