Rectified and filtered DC power supply MURRELEKTRONIK

The galvanic isolation of the input and output sides as well as the alteration of the
mains voltage (i.e. into a low voltage) is achieved by the transformer.
The power supply units to EN 61558 are built with either top or side mounted
bridge rectifier and electronics. This both protects the electronics and enables the
units to meet touch protection guidelines BGV-A2 and EN 60529.
All transformers/power supply units are fitted with angled fixing brackets and key
holes to aid simple mounting.
In applications where less than 5 A is required, it is often not practicle to replace
linear regulated units with primary switch mode units. This is particularly true
where the whole system is supplied by an unregulated or large switch mode unit.
