    Can somebody explain what does it mean by the following line from description - " if you want to add current, please put insurance below the transformer replaced the 0-ohm resistor, maximum 50mA, but does not recommend increased.)" BTW it came very soon . very pleased.

    Works well as adverstised . good price point I have a query though - can somebody explain following lines from the description as to how we can increase the current output. - if you want to add current, please put insurance below the transformer replaced the 0-ohm resistor, maximum 50mA, but does not recommend increased

    Cospa is the best. Easy to use and easy to adjust voltage in VR is also attractive. The high voltage output terminal is small and convenient.

    Works fine for my Geiger counter, though I do have my doubts about the voltage stability. Furthermore the isolation of the transformers inner windings does not seem to be that good. If i push on the transformer during operation the voltage spikes.

    Can't output the advertised 10 ma without the voltage dropping to 60, and no voltage regulation if the imput changes. But if you need a really low power (like charging a small capacitor for me) it can be handy.

    dc dc converter werkt perfect zelfs op 3v werkt hij nog. bij 3v gaat hij nog tot 1600v maar of dan de specificaties nog kloppen??? ik gebruik hem voor een gm tube aan te sturen

    Simple à mettre en œuvre et plutôt pratique (notamment grâce aux tensions intermédiaire comme l'indiquait un autre client dans un autre commentaire). Attention, très faible courant disponible !
