Product Description:
The 0PS1020.0 belongs to the 0PS Power Supplies series manufactured by B & R Automation. It is a DIN-rail-mounted power supply designed to energize PLC racks, remote I/O stations, and sensor networks in industrial automation panels. The unit converts single-phase mains power into regulated DC power suitable for control electronics. Its compact format allows it to be installed with other panel-mounted control components while maintaining an organized power distribution layout.
The converter delivers a tightly regulated output of 24 VDC ±1% at a continuous 2 A, providing a maximum load capacity of 48 W. An operating efficiency above 88% minimizes cabinet heating and reduces dissipated power. Energy stored in the bulk capacitors maintains the output for more than 170 ms after a 230 VAC dropout, allowing connected controllers to perform an orderly stop. For brief load surges, a boost current of 2.9 A is available without triggering the protection circuits. The DC-OK relay provides 24 V at 20 mA so supervisory logic can detect undervoltage events. This relay output can be connected to a controller input for continuous power-status monitoring.
Startup stress on upstream breakers is limited by an inrush current below 15 A, while a built-in 2.5 A slow-blow fuse protects against sustained faults. Steady-state noise is constrained to a peak-to-peak level below 20 mV at 20 MHz, and switching spikes remain under 100 mV. The housing measures 45 × 99 × 107 mm and fits standard compact enclosures. An IP20 rating prevents accidental finger contact with live parts while permitting installation inside a protected control cabinet. The unit can operate at altitudes up to 3000 m without derating. The supply reaches full regulation in less than one second after power is applied, and the DC-OK contact resets automatically when normal output conditions return.
