APPLICATIONS

• Control application in low- and medium-voltage distribution panels and switchboards where it is necessary to place an analyzer on the DIN rail due to problems of space.
• Alarm control. Maximum value, minimum value and programmable delay.
• Control of active or reactive energy by impulse output.
• Capture of maximum and minimum instantaneous data of electrical parameters measured.
