Voltage / Current Output

MAX Power


24V / 16.7A*



48V / 8.3A* 400W8

*The actual current and power output will depend on the output modules selected. 

There are 21 different output modules to choose from, with the following voltages: 5V, 12V, 15V, 24V, -5V, -12V, and-15V. These are offered with several different current outputs. 

Not all modules can be used in both base models, check the data sheet to ensure that the module you wish to use is compatible with the base unit selected.  

Do not hesitate to contact ADM on 1300 236 467 if you would like help in selecting the correct models. A member of our expert team will gladly help. 

Unlike most other multi rail power supplies, the new UMP-400 series has no minimum load requirement for it to function correctly. Usually, you would have to check the data sheet for the minimum load requirement on each channel and check that you could fulfill this load requirement. With the UMP-400 you can relax. 

For maximum reliability these power supplies are not fan cooled. Instead they rely on air convection and heat being conducted away through the metal enclosure of the equipment they are mounted in. The data sheet details the minimum surface area to ensure adequate cooling. 

With a 3 year warranty and an operating temperature range of –30 ~ +70 °C, the MEAN WELL UMP-400 series is an ideal solution that call for a highly reliable multi rail power supply, that can fit into a small space.
