Product Description:

The NTM02.1-024-024-16 is a power supply unit produced by Bosch Rexroth Indramat and assigned to the NTM Power Supply Units series. It converts an upstream AC link into a stabilized 24-volt DC rail that feeds control circuits, sensors, and auxiliary actuators inside drive cabinets. In automated lines, this regulated source keeps logic, feedback electronics, and low-power relays at a constant potential even when the incoming supply is affected by larger inverter loads. This type of supply is often used where a separate low-voltage source must remain stable while motors and drives cycle on the same machine.

The converter delivers a nominal output of DC 24 V at up to 16 A, allowing parallel connection of PLC racks, contactors, and fieldbus couplers without the need for multiple supplies. The output is regulated, so load changes within the rated current window do not cause unacceptable voltage drift that could reset digital boards. Built-in short-circuit and open-circuit protection disconnects the channel if a load shorts or becomes disconnected, preventing conductor overheating and allowing normal operation to resume after the fault is cleared. The front housing spans only 115 mm across the panel, so it occupies a single standard slot alongside servo drives while leaving room for wiring ducts and terminal access. This makes one module practical for mixed control loads that switch at different times during operation.

Mechanical layout also supports dense cabinet packing. The unit has an overall depth of 321.5 mm and a height of 290 mm, dimensions that align with 300 mm deep enclosures and 19-inch sub-racks. A minimum rear and side clearance of 50 mm is required to maintain convection airflow across the internal heat sink. The housing can be mounted directly on DIN rails or base plates, and the clearance space allows warm air to move away from neighboring modules during continuous operation. The tall enclosure also supports vertical airflow, which helps the heat sink release heat without forced cooling.
