NAM04.1-480-0650-NN

The Bosch Rexroth Indramat NAM04.1-480-0650-NN module belongs to the NAM Power Line Form Modules series, delivering robust power conversion capabilities for industrial drive systems. With an Input Voltage range of 380-460V AC and a Nominal Current rating of 650 A, it efficiently converts three-phase line voltage into a stable DC link. Featuring Choke Terminals 1L+ / 2L+ and Output Terminals U2-V2-W2, this module’s primary function is to supply a reliable DC bus voltage of 300V to servo drive units in automation setups.

Designed for seamless integration into Rexroth Indramat drive systems, the NAM04.1-480-0650-NN offers detailed technical specifications that ensure high performance under varying load conditions. Its 380-460V AC input couples with internal chokes to minimize line distortion, while the 650 A nominal current rating supports high-power demands. The 300V DC output is regulated with precision, reducing voltage ripple and optimizing energy delivery. The dedicated U2-V2-W2 output terminals guarantee secure connections to KDV 4.1 or KDV 2.3 power supply modules. Internal choke terminals 1L+ / 2L+ are designed to suppress harmonics and protect downstream electronics, distinguishing this module by its advanced line filtering capabilities.

Beyond its core power conversion role, the NAM04.1-480-0650-NN emphasizes compatibility and durability in industrial environments. It operates reliably within a standard ambient temperature range of +5 to +45 °C and is rated to an IP10 protection class, ensuring basic ingress protection. Insulation class C maintains electrical integrity under thermal stress, and the unit can be installed at altitudes up to 1000 meters without derating. The module’s efficient choke design and stable DC output contribute to energy savings and reduced wear on connected servo drives. By providing consistent, high-quality DC bus power, this line form module enhances system uptime and simplifies drive architecture, delivering clear benefits for demanding industrial automation applications.
