Multi Rail Power Supplies In Stock
ADM stocks a wide range of enclosed multi rail power supplies from MEAN WELL.
There are in fact two types of multi rail power supply available:
- Open Frame Multi Rail Power Supplies
- Enclosed Multi Rail Power Supplies
Open frame multi rail power supplies will be the first choice for original equipment manufacturers (OEMs). They don't have a metal enclosure, which means they are generally a more cost effective options.
OEMs designing and building medical appliances will be interested to know that many models within the MEAN WELL range carry medical approvals.
Power outputs range from as low as 5 Watts up to power supplies with a 250 Watt output. Dual, triple and quad output options exist within this range.
This type is typically available for special order only.
Enclosed multi rail power supplies have a metal enclosure, or cage. These can be used inside finished equipment, or a switchboard or control panel. There are DIN rail clips and brackets available for some of the smaller models.
Power output options range from 35 Watt up to 125 Watts. Again, there are dual, triple and quad output options available. Many models are available from stock.
