Lap-type rectifier `` LV ''.

Power supplies. Rectifiers, stabilizers, autotransformers, transient transformers, etc.RectifiersLapovy rectifier "LV" from the 1st quarter of 1927 produced electric trust of low-current factories. "LV" is intended for rectifying alternating voltage to constant voltage and replacing the anode batteries of power supply of radio receivers with power supply from the electrical network.
