Product Description:
The 0PS1020.0 is an outstanding automation tool manufactured by B&R Automation for single-phase industrial systems. The 0PS1020.0 functions as a power supply module, delivering a nominal DC output voltage of 24 volts. Like most B&R 0PS products, the 0PS1020.0 features an optimized fan design and a top-hat rail for DIN rail installation. At its nominal DC output, the corresponding power developed across the output terminals is 50 watts. During full-load operating conditions, the 0PS1020.0 achieves an efficiency of around 88.5%. At this efficiency, the device loses around 6.8 watts of power at 230 V AC input.
At convection cooling, the 0PS1020.0 can safely accommodate a continuous rated current of up to 2.1 amperes. Depending on the front potentiometer’s position, the 0PS1020.0’s DC output voltage may vary between 24 and 28 V. Like other single-phase power supply units by B&R Automation, this device is compatible with both AC and DC systems. Based on B&R’s documentation for the 0PS1020.0, the admissible AC input and DC input ranges are as follows: 85-264V and 85-375V, respectively. At an AC input voltage of 100 V, the 0PS1020.0 draws around 1 ampere. Meanwhile, at an AC input of 196 V, the unit only draws 0.6 A. Although this device does not require an external fuse during operation, a separate circuit may be used to provide the same functionality. The device, however, already employs an internal fuse.
In terms of its exterior qualities, the 0PS1020.0 can be considered a small power supply module. Measuring only 45 by 75 by 91 mm, this device is suitable for applications with strict space requirements. It comes with a robust plastic housing and weighs only 0.24 kilograms.
