DC power equipment

DC boards

DC boards are designed to provide a guaranteed supply of DC electrical energy with a voltage of up to 500 V of critical systems (control, protection, automation and emergency) at energy and industrial facilities.

DC boards, depending on the configuration, may include the following main components:


Corporation "ELCOR" produces DC boards in the following versions:
