Product Description:

The NAM 1.3-08/S007 is manufactured by Bosch Rexroth Indramat and is part of the NAM Power Line Form Modules series. It works as a power adapting module that prepares three-phase mains power for the common DC bus used in multi-axis automation racks. By rectifying and filtering incoming energy, the unit creates a stable link voltage for connected inverter drives and helps absorb regenerative peaks that occur during rapid braking events in coordinated motion systems.

The module accepts a line supply of 3 x AC 380 to 460 V over a frequency range of 50 to 60 Hz. After conversion, it delivers a DC link held at 300 VDC, providing a constant source for connected drives throughout normal operation. Voltage ripple and electromagnetic interference are reduced by an internal network consisting of a commutation choke, buffer capacitor, and DC bus choke. The device is classified as a power adapting module, so it conditions electrical energy while separate units handle control functions. Electrical connection to adjacent components is made through a pluggable bus connector, and the power terminals are sized to carry the full cabinet load without additional fuses.

A plug-in 16-pin system cable links the module to the upstream TVD 1.3-08-3 supply and downstream inverters. The housing has a width of 105 mm, a depth of 355 mm, and a length of 390 mm, which allows dense stacking while still leaving room for the magnetic elements inside. Installation guidelines call for at least 80 mm of free clearance to maintain airflow around the heat sink and support steady thermal performance. Alignment holes match standard rail patterns so the DC bus bars mate correctly on insertion, and the rigid enclosure keeps the coil laminations fixed during transport and operation, which helps reduce mechanical humming under high current.
