OUTPUT Voltage/Current Ranges
Output Setting & Control Voltage Setting: By coarse and fine controls. Current Setting: By single logarithmic control. Output Mode: Constant voltage or constant current with automatic cross-over. CC indicator in constant current mode. Output Switch: Electronic, non isolating. Preset voltage and current limit displayed when Output off. Output Performance Ripple & Noise: Typically <2mV rms, <10mV pk-pk, (EX355R, EX354RD, EX354RT) CV mode, 20MHz bandwidth Load Regulation: <0.01% of maximum output for a 90% load change (using remote sense). Line Regulation: <0.01% of maximum output for 10% line change. Transient Response: <200us to within 50mV of setting for a 5% to 95% load change. Temp. Coefficient: Voltage: typically <100ppm/oC. Output Protection Output Protection: Outputs will withstand forward voltages up to 40V (EX355R, EX354RD,& EX354RT); 22V (EX1810R); 25V (EX2020R); 48V (EX4210R). Reverse protection by diode clamp for currents to 3A. Output Connections Output Terminals: Universal 4mm safety binding posts on 19mm (0.75") spacing. Terminals can accept fixed shroud 4mm plugs, standard 4mm plugs, fork terminals and bare wires. Remote Sense Sense Selection: Voltage sensing is selected as Local or Remote by front panel switch. Sense Terminals: Sprung loaded screw-less terminals. METER SPECIFICATIONS Display Type: Dual 4-digit meters, 14mm (0.56") LED.
