Voltage: 0-20V Current: 0-3A 60W Single output Constant voltage (CV) and Constant current (CC) modes Front and rear output terminals Auto-parallel, Auto-series and Auto-tracking operation 10 turn voltage and current adjust potentiometers Overvoltage protection, remote analog programming, and remote sensing The flexible E3615A 60-watt, single-range power supplies can be used as either voltage or current sources. When output terminal voltage increases to a preset shut-down level, an overvoltage protection circuit disables the output to protect the device under test (DUT) from damage. The overvoltage protection feature is easily monitored and adjusted from the front panel. Using remote sensing capability, these instruments automatically compensate for voltage drop in the load leads, so you get accurate voltage at the DUT. You can combine multiple units in auto-parallel, auto-series and auto tracking configurations for greater output voltage or current capacity. Front and rear output terminals allow flexible configuration. Output voltage and current can be controlled with external 0- to10-volt analog voltage or variable resistance.
