Product Description:

The NTM02.1-024-024-08 is a power supply unit produced by Bosch Rexroth Indramat in the NTM Power Supply Units series. Installed in automation cabinets, it conditions 24-volt direct current so that controllers, field devices, and drive logic receive stable low-voltage power. It forms part of the low-voltage subsystem that isolates sensitive electronics from the high-power sections of an Indramat drive package.

It accepts an input of DC 24 V ±10 % and delivers a regulated output of DC 24 V at up to 8 A, enabling simultaneous feed of sensors, relays, and bus couplers. Operation remains continuous provided ambient air stays below 40 °C, and humidity can rise to 90 % without condensation. Temperature change is limited to 20 K per hour to prevent component stress. The module can sit unpowered for two years with no loss of function. Panel mounting uses 88 mm hole spacing sized for M5 screws, which supports secure installation. The permitted voltage margin absorbs small bus droops during emergency-stop conditions, and the foldback protection built into the converter shields upstream fuses from surge currents.

Rated for environmental class 3K3, the supply withstands light dust and moderate vibration common to machining cells. A compact shell only 96.7 mm deep, 105 mm wide, and 140 mm high conserves enclosure space and maintains airflow paths. Storage temperatures from −25 °C to +70 °C are permissible when moisture is controlled. The housing can be installed next to servo drives and PLC racks without requiring extra shielding or heat sinks. Clear side gaps should be kept around the housing so that convective cooling can remove transformer heat, especially when the supply is stacked above inverters.
