Product Description:

The NTM02.1-200-570-00 is a compact power supply module manufactured by Bosch Rexroth Indramat within the NTM Power Supply Units series. It converts incoming alternating mains power into a regulated high-voltage DC bus that feeds servo drives and motion controllers in automated machinery. By providing stable DC energy, the module isolates sensitive electronics from line disturbances and removes the need for each axis amplifier to include its own rectifier stage.

The supply accepts an input of 200/230/260 V AC ±10%, allowing installation on low- or medium-voltage plant power without tap changes. Internally, this energy is converted to 570 V DC, which is suitable for the DC link used by Indramat drive controllers. With a continuous rating of 100 W, the module can energize control electronics and the quiescent requirements of several low-power axes. Output current is limited to 0.175 A, so downstream equipment must rely on their own intermediate capacitors to handle dynamic loads. During steady operation, the device draws only 0.5 A from the mains, which helps reduce heat dissipation in compact cabinets.

At power-up, inrush reaches 10 A, so a time-lag circuit breaker should be used to avoid nuisance trips while still coordinating with the upstream 4 A thermal-magnetic protector provided for nominal service. The unit synchronizes to plant supplies at 50/60 Hz, which allows operation without hardware changes across common utility frequencies. It is classified for 3K3 conditions, meaning it is intended for indoor industrial locations with limited dust and moderate temperature variation. Because the enclosure carries an IP00 rating, the module must be installed inside a closed electrical cabinet to prevent accidental contact with live parts. The device weighs 3.6 kg and mounts on a back-panel footprint of 105 mm by 96.7 mm with a height of 140 mm. Wiring uses a 1.5 mm² (AWG 16) cable cross-section.
