Adjustable power supplies SP150 are suitable to be used when it is necessary to often change the output voltage. Power supplies are intended for general use to feed electric and electronic devices with direct voltage in covered rooms, in environments without risk of explosion. Because this is a switched power supply, it achieves high efficiency even with low output voltages. Due to this the power supply does not produce too much heat with low output voltages as is usual with linear power supplies. Output voltage can be set from 0 V up to 30 V or from 0 V up to 50 V depending on the model of power supply. The power supply is also equipped with adjustable current limitation. Currently set voltage and drawn current can be checked on a measuring device of the power supply.


Warning: The current limitation is operational only in steady state. During transitional event the power supply can deliver higher current than set in current limitation. This is caused by capacities which are connected to power supply's output.
