FIELD: electricity.
SUBSTANCE: invention is related to a capacitive power supply unit, moreover to an electronic device equipped with the capacitive power supply unit. To this end at the first facility the capacitive power supply unit contains an input part (10) having input contacts (Ln, Nt) to connect an alternating-current source and a capacitive coupling; a rectifying part (20) connected through the capacitive coupling to the input contacts (Ln, Nt) and an output part (30) connected to the rectifying part, there's an auxiliary device (R1) limiting start-up current where output contacts (V+, V-) are connected to the respective contacts of a device (D5) limiting output voltage, and in-series capacitive impedance (Zdc) conducting direct current has a resistive component with a resistive value equal to at least 0.2 of the first circuit resistive value. At the second facility the electronic device contains a power input (101), (102) for connection to the supply mains; a capacitive power supply unit (110) coupled to the power input; the first functional unit (140) receiving power supply from the capacitive power supply unit.
EFFECT: reduction of heat dispersion losses.
