Voltage regulating device for consumers at distances apart assigned with measurement devices has an adjustable voltage supply, a sensor wire to transmit a measurement signal and an adjusting device

摘要

Voltage control (1) is achieved with a load resistor (3). A consumer (2) links via wires to specific resistors (4) and sensor lines (5). A constant source (6) of voltage is connected on the non-inverting input of an operational amplifier (7), the output of which links to a source (9) of voltage regulated by a transistor for adjusting voltage for the consumer.
