Work in remote control via RS-232 interface.


Operating conditions B5-88/2:


The ambient air temperature - 5° C to 40° C.

Relative humidity at 30° C - 90-95%.

Atmospheric pressure 750+30 mm of mercury.

Mains voltage - (220±22) V.

Mains frequency - (50±1) Hz.

Power consumed by the device at the rated voltage - 15 V·A.


Manage source output parameters can be performed manually using the buttons and encoder on the front panel or remotely via existing interfaces RS232, that provides the source B5-88/2 (or group of sources) as part of automated measuring systems.

Rectangular load characteristic (voltage regulation, current stabilization) allows you to connect the output of several parallel sources, summarizing their output.


Execution B5-88/2 has an additional option reverse current at the terminals, which are mounted on the rear panel. This feature in conjunction with a programmable profile, described below, enables a better chemical coating for electroplating operations.
