FIELD: power supply units.
SUBSTANCE: invention relates to equipment for supplying electrical power to an electrical device. The result is achieved by indicating the desired power level to be supplied to the electrical device. Electrical power is received as DC power by means of a constant current regulator unit (102), which inverts DC power to AC power and supplies AC power to be converted to output power, in this case, the AC-power adjustment tool is designed to: adjust the frequency to obtain the desired power level if the desired power level is between the first threshold value and the second threshold value; adjust the waveform to obtain the desired power level if the desired power level is below the second threshold value; and adjust the output voltage to obtain the desired power level if the desired power level is above the first threshold value.
EFFECT: ensuring the supply of electrical power to an electrical device by directly supplying power to LED lamps using only the output signal of the constant current regulator unit.
