Product Description:

The NTM02.1-230-024-15 is a power supply unit produced by Bosch Rexroth Indramat within the NTM Power Supply Units series. It converts factory mains into regulated low-voltage energy so that drives, PLCs, and I/O modules inside an automation cell receive consistent 24-volt power even when line conditions fluctuate. The module mounts inside a control cabinet and supports systems that require continuous auxiliary power during machine start-up, production, and controlled shutdown.

The device accepts an input of 230 V AC at 50/60 Hz, and the permissible deviation of the line is ±10 %, allowing installation on feeds that are not perfectly centered on nominal voltage. Maximum draw from the supply network is limited to 1.5 A, which simplifies circuit-breaker sizing and keeps heat generation moderate. Internally, the converter delivers a regulated output of 24 V DC that remains stable when only AC power is present or when an upstream 750 Vdc bus is connected. The housing carries an IP20 rating and is intended for clean, ventilated cabinets without dripping moisture. Mechanical dimensions are 115 mm in width, 321.5 mm in depth, and 290 mm in height, enabling side-by-side mounting with other Rexroth modules on a standard backplane.

When supplied by the internal high-voltage DC link, the unit can source up to 15 A; if only the AC terminal is energized, the continuous current is 5 A. Resistive and conversion losses are capped at 100 W, so the thermal load on the enclosure remains manageable with normal cabinet airflow. Overall mass is 7.5 kg, which provides sufficient transformer and filtering capacity without making the unit excessively heavy for cabinet mounting. The DC input window spans 750 V with a tolerance of −40 % to +20 %, ensuring compatibility with shared-bus drive systems during regenerative operating modes.
