DC voltage source (DC) & nbsp; B5-47 & nbsp;. For power radio devices with stabilized voltage and current in the laboratory and workshop conditions

The magnitude of the output voltage and current can be adjusted manually or remotely electrical signals in the code 8-4-2-1.

It is possible to source operation with an isolated output, and by grounding terminals of either polarity.

output voltage B5 -47 & nbsp; guaranteed at & nbsp; not only the terminals but also directly on the load, which is achieved through the use of

& nbsp four-line load system connection to the source;.

B5-47 operating principle of & nbsp; power:

& nbsp;

DC power Sources are from & shy ; fight compensatory stabilizers sequentially enabled & shy; nym regulatory element and a feedback amplifier. To reduce the power dissipated in the regulating member, reducing the dimensions and weight of the power transformer & shy; torus voltage across the control element is stabilized through controlled network inverter. Devices can ra & shy; bot in the constant voltage mode and constant current mode. All sources B5-46 DC, B5-47, B5-48, B5-49, B5-50 made by a single scheme, differing only types of components.

In order to allow both manual and remote control output voltage and output current in the instru & shy; rah uses two DACs which provide transformation & shy; of the digital information coming either from the front panel or from any control device via the control connector on the rear panel, to an analog value soprotiv & shy; tions introduced into measuring bridges. Switching soprotiv & shy; tions carried out by means of electromagnetic relays, koto & shy; rye provides both galvanic isolation you & shy;
