This invention belongs to the field of electrical engineering, namely adjustable direct current power-supply sources intended for electrochemical protection equipment used to protect against soil corrosion of underground metallic equipment and mains. The power-supply source has more than one independently controlled output channels. The adjustable direct current power-supply source, which has an output voltage and current electronic controller and grounding transformer, the primary winding of which is connected through the first overload protection device and voltage indicator to automatic switch terminals of an alternating current power-supply source network, and a secondary transformer winding is connected to a diode bridge inlets, the leads of which are connected to a load circuit, where there is another overload protection device and voltage and current meters. The novelty is that the load circuit consists of one or more output channels, each of them having a switched-in separate output voltage and current electronic controller, a separate overload protection device and a separate voltage and current meters. |
