R911278493 (DZB01.1-W720N)

Description

The R911278493 (DZB01.1-W720N) is an auxiliary bleeder component designed by Bosch Rexroth for use with the DKR 4.1 range of drive controllers. Marked with a line code of 01 and version code of 1, it can be externally fitted to the drive controller. The unit is designed for operation with uncoupled three-phase systems, mandating the use of an isolating transformer for overvoltage protection. If inconsistent with the rated power voltage, an autotransformer is required. The product employs internal air circulation cooling via an inbuilt blower rated at 0.22A and 24VDC +/-20%. Equipped with a protective rating of IP 20, it complies with IEC 529 or EN 60529 specifications. The bleeder's specifications include a peak power rating of 200kW and a continuous power rating of 3kW. Additionally, it delivers a maximum brake energy of 720kW and operates nominally at 24VDC with an operating temperature range of 5-45°C.
