Product Description:
The NAM04.2-480-0450-NN-120 is a power line form module in the NAM Power Line Form Modules series manufactured by Bosch Rexroth Indramat. It converts incoming three-phase mains power into a stable DC link that supplies multiple drive controllers within an automated production cell. By combining line isolation, energy storage, and protective switching in one assembly, the module streamlines cabinet layouts and supports coordinated servo axes and spindle inverters. This arrangement helps distribute power from a central source across interconnected motion components in the same system.
Electrical performance data describe how the module operates during control and load changes. A line-side breaker rated at 3.0 A protects the 120 V control circuit fed by the internal transformer. Logic components operate at a nominal control frequency of 60 Hz under a supply of 120 VAC. On the DC side, a capacitor bank sized at 150 mF stores energy and filters ripple for downstream inverters. The bus can deliver up to 450 A of continuous current, while an integrated preload path limits inrush through a 1 A charging stream. Short-term load spikes are buffered by the capacitor and a pulse path that releases energy for 150 ms, which helps reduce bus sag during rapid acceleration events.
Mechanical and connection data support safe installation inside the drive cabinet. The module draws only 15 VA of housekeeping power, yet it can supply a transient pulse of 1000 VA when commanded by the drive stack. Because the enclosure is IP00 and assigned environmental class 3K3, it must be mounted inside a filtered cabinet to keep exposed internal sections protected from airborne contamination. The K1 power terminals accept 2 × 120 mm² copper busbars that are secured with a tightening torque of 35 Nm. For system design, the unit weighs 20 kg and provides two pluggable signal headers: X10 with 13 poles and X20 with 11 poles, enabling discrete status and interlock wiring without additional terminal blocks. These connections allow the module to interface cleanly with the rest of the control cabinet through straightforward signal wiring.
