Huntington, UK TTi (Thurlby Thandar Instruments) has extended its EL Series of low-cost and compact linear bench power supplies with two new models that offer both higher power and higher current levels. The EL155 provides 0-15 V at 0-5 A (75 W maximum), while the EL303 provides 0-30 V at 0-3 A (90 W maximum). Both models retain the features that characterise the EL Series: namely, silent convection cooling and linear regulation for low output noise combined with excellent transient performance. They also share the compact dimensions of the series and the convenience of dual digital displays and a DC output switch. The EL Series now comprises eight models including single-, dual- and triple-output versions with maximum power ranging between 30 W and 90 W per output. Both new models measure 140 mm wide x 160mm high x 295 mm deep and weigh 5 kg. The price for each unit in the UK is £189 (plus VAT).
