The R911278493 (DZB01.1-W720N) is an auxiliary bleeder module engineered for integration with DKR 4.1 drive controllers from Bosch Rexroth. It features external mounting capability and is intended for operation within uncoupled three-phase systems, requiring an isolating transformer for overvoltage protection and, if necessary, an autotransformer for voltage matching. The module provides a peak power rating of 200 kW, continuous power output of 3 kW, and a maximum brake energy absorption of 720 kW·s. It is internally cooled by a 0.22 A, 24 VDC (±20%) blower and carries an IP20 ingress protection rating compliant with IEC 529 or EN 60529. The device operates nominally at DC 24 V, supports an air-cooled configuration, and is suited for environments with ambient temperatures from 5°C to 45°C.
