HIGH VOLTAGE. EXACTLY. The iseg Spezialelektronik GmbH company specialises in the development and production of High Voltage Power Supplies for Industry and Research. Our business goal is to provide the most precise and cost effective high voltage power supplies on the market. The most precise iseg devices guarantee a ripple and noise down to 5·10-7 of the adjusted output voltage. That means for an output voltage of 10,000 V the ripple is below 5 mV.
