Product Description:

The 0PS340.1 power module is manufactured by B&R Automation as part of the 0PS Power Supplies series. It serves as a three-phase, cabinet-mounted source that converts incoming AC energy into a tightly regulated DC line for programmable controllers, I/O modules, and motion drives used in automated machinery. By maintaining a constant output across wide load swings, the supply supports deterministic logic processing and actuator response in production cells, conveyors, and packaging stations. Its design also integrates diagnostic contacts that signal operating status to the control system.

The supply delivers a nominal output of 24.5 V ±0.5%, so downstream electronics receive voltage that deviates by less than half a percent from the setpoint. At full load, it can provide 40 A, a current level sufficient for several servo drives and high-density I/O racks. Continuous power capability reaches 960 W, and the three input lines draw 3 × 3.0 A each when the unit operates at rated mains voltage. Conversion stages operate at an efficiency of 92.5%, meaning only a small portion of the incoming energy is dissipated as heat. The three-phase topology also minimizes ripple, improving the stability of analog sensors and fieldbus interfaces.

An internal crowbar limits the output to 32 V ±10% during fault conditions, and reverse energy from inductive loads is tolerated up to 35 V without damage, ensuring compatibility with motor braking circuits. Under rated operation, residual dissipation stays at 78 W, a value used to size cabinet airflow for the enclosure, which measures 124 mm in height, 275 mm in width, and 117 mm in depth. Installation weight is 3300 g, allowing secure fastening on standard DIN rails even in applications subjected to vibration. The electronics remain functional in ambient humidity up to 95%, supporting deployment in washdown or high-condensation zones of a plant.
