al-yeti Posted May 7, 2015 Share Posted May 7, 2015 or variable psu Problem here would be current then , increase voltage won't give you increase current or have I mixed that up? Quote Link to comment Share on other sites More sharing options...
james.wilson Posted May 7, 2015 Share Posted May 7, 2015 no, increase the voltage it (dc) will half the current demand, ac theory is more log vs the lin of dc. DC is easier as its pure ohms law, Ac theory adds a little more ie impedance but its similar, ish Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
