The EX Series for users who require higher power levels. Mixed mode regulation gives excellent performance. By adding four digit meters and switchable remote sensing, the EX-R series offers much higher precision whilst retaining the simplicity of operation which many bench-top power supply users prefer Single outputs 42V/10A Independent digital voltage and current meters with 4 digit resolution Switchable local or remote sensing Constant voltage or constant current operation Variable 1.5 - 5.0V auxiliary output at 5A (EX354RT) Compact design uses less bench space Silent fan-free cooling DC output switches, automatic mode indication
