Output Current Setting: Direct keyboard entry or quasi-analogue rotary control; setting resolution 10mA. Output Mode: Constant voltage or constant current with automatic crossover. Output Switch: Electronic. Preset voltage and current displayed when off. Output Terminals: 4mm terminals on front panel, screw terminals at rear. Sensing: Remote via rear panel screw terminals or direct via shorting strip (supplied). Output Impedance: <1mΩ in constant voltage mode. >5kΩ in constant current mode (voltage limit at max.). Output Protection: Forward protection by Over-Voltage-Protection (OVP) trip; maximum voltage that should be applied to the terminals is 50V. Reverse protection by diode clamp for reverse currents up to 3A. OVP Setting: Direct keyboard entry. OVP Range: 1V to 40V (35V/10A); 1V to 25V (18V/20A). OVP Delay: <200μs Load & Line Regulation: <0.01% of maximum output for 90% load change or 10% line change. Ripple & Noise: <1mV rms typical in constant voltage. <3mA rms typical in constant current. HF Common Mode Noise: Typically <3mV rms, <10mV peak. Transient Response: 20μs to within 50mV of setting for 90% load change. Temperature Coefficient: typically <100 ppm/°C. Protection Functions: Overvoltage trip; regulator overtemperature; sense miswiring. Status Indication: Output off lamp; constant voltage mode lamp; constant current mode lamp; trip message on display. METER SPECIFICATIONS Meter Types: Dual 4 digit meters with 12·5mm (0.5") LEDs.
