MULTI-PURPOSE CHARGING DEVICE AND METHOD OF CALIBRATION OF VOLTMETER CONNECTED TO CHARGING DEVICE TO CHECK OUTPUT VOLTAGE

摘要

FIELD: electrical engineering; storage batteries and capacitors. SUBSTANCE: device has differential amplifiers, light radiating element, resistors, voltage divider, transistor and amplifier of high input resistance. Facility to be charged is connected to output of charging device. Light radiating element light when current flows in circuit of facility under charging. Brightness of element depends on current value in facility under charging. Charging is carried out automatically. EFFECT: enlarged operating capabilities. 16 cl, 11 dwg
