The New XEL series combines the traditional benefits of linear DC power supplies with new and important features: • Linear regulation for ultra-low output noise and fast transient recovery • High accuracy four digit fixed-resolution meters • True analogue controls for quick and intuitive adjustment of voltage and current • DC output switch to check settings before applying them • Remote voltage sensing for exceptional load regulation • Current meter averaging to reduce jitter with rapidly varying load currents • High power density - up to 90 watts from an ultra-compact 3U 1⁄4-rack case size • Significantly higher energy efficiency than conventional linear regulated designs by using an advanced phase-controlled pre-regulator • Low current range giving 0.1mA meter resolution and finer low current setting • V-Span allows the user to redefine the end-stop values of the voltage control, giving high- resolution analogue control over the exact voltage range needed • S-Lock digitally locks voltage and current settings at the touch of a button • Setting limits can be viewed at any time • Safety binding post terminals are touch-proof and uniquely accept fixed shroud 4mm plugs as well as standard plugs, bare wires and fork connectors
