    DANA-Thyristors Regulation AC/DC Power Supplies - DE Series



    It is a method of regulation used when you have to get a good efficiency without having the problems

    involving switching Power Supplies which could spread not controllable noise and ripple level similar to linear Power Supplies with spike frequency at grid frequency.
    Schematically very simple offer, in addition to low prices, extremely stable and therefore particularly suitable for use in test of life for evidence of reliability and robustness of motors, resistors and more.
    It is possible to program in local mode, through multi turn potentiometers, or in remote mode by analog signal 0 ÷ 10 Vdc and opto-insulated feed-back 0 ÷ 10 Vdc to check set output.
