Product Description:
The NAM04.2-480-0650-NE-120 belongs to the NAM Power Line Form Modules series produced by Bosch Rexroth Indramat. This module conditions three-phase line power for drive systems, providing the DC-link and protection functions needed to run multiple inverters from a common supply. By integrating power conversion and line monitoring into one unit, it simplifies cabinet layouts in automated machinery where space and centralized power management are important.
The control section operates at 120 V AC and a line frequency of 60 Hz, and a separate control breaker rated at 3.0 A isolates this circuitry. Auxiliary logic and indicator circuits draw only 15 VA, helping keep panel heat low. The open-frame housing carries an IP00 rating, so installation inside a closed cabinet is required. Environmental class 3K3 sets the permissible temperature, humidity, and non-condensing operating conditions. The unit detects the presence of line voltage before energizing its contactor, preventing unintended startup. Wiring to the line input must use two parallel sets of two 240 mm² conductors, limiting cable losses on high-current paths. The power contactor terminals need 35 Nm of tightening torque to ensure secure connections, while the Q1 feeder breaker is sized at 1.6 A and can interrupt faults up to 100 kA without external fusing. A transient suppression network absorbs 1000 VA for 150 ms, reducing overvoltage stress on downstream drives.
The power stage can deliver a continuous 650 A to the DC bus, supporting high-current supply demands across connected inverters. Its bulk capacitors provide a maximum energy storage of 150 mF, which helps stabilize the link during rapid load changes. Despite the high current rating, the module’s mass is only 20 kg, which helps simplify cabinet mounting. The compact mass is useful when the unit is installed on a back panel within a centralized drive cabinet.
