Product Description:

The NAM04.2-480-0650-NE-230 is a power line form module built by Bosch Rexroth Indramat for the NAM Power Line Form Modules series. In multi-axis drive systems, this unit sits between the mains supply and the DC bus, shaping incoming line power and coordinating energy flow to connected inverter racks. By performing this function, it helps protect downstream components and stabilizes the intermediate circuit so motion controllers can respond predictably under dynamic industrial loads. This arrangement also supports shared bus operation when several connected axes accelerate or decelerate at different times.

The internal circuit breaker is rated at 1.6 A, while its short-circuit breaking capacity reaches 100 kA. These values show how the module isolates fault currents without external fusing. A control voltage of 230 V AC energizes the logic and auxiliary relays through a 13-pole terminal strip that simplifies wiring to supervisory PLCs. Interface RZR01 transfers status information, and the unit incorporates mains voltage detection to disable drive release until line conditions are within tolerance. Continuous load sharing is allowed up to 650 A on the DC bus, and an IP00 enclosure rating means the module must be installed in a housing that provides the required protection against contact and debris.

The intermediate circuit can accept a capacitance of 150 mF, which helps limit voltage ripple and store regenerative energy during deceleration. Conducted emission filtering is classified as A2, and the control electronics draw only 15 VA during steady operation. During line disturbances, the energy reserve can withstand a transient pulse of 1000 VA / 150 ms, helping downstream drives remain active long enough for an orderly stop. The unit is built for environmental class 3K3, which suits ventilated production areas with moderate humidity and dust. Total transport weight is 20 kg, which affects panel handling and installation support requirements.
