EV Series

Features

• Input. Single phase over the input voltage range of 198 VAC to 264 VAC, with active power factor correction.
• Floating Output. Either output termi nal may be grounded for operation as a positive or negative supply.
• Embedded Microcontroller control. Front panel digital encoders provide high resolution local adjustment of volt age and current program. Integral RS-232, RS-485, USB and optional Ethernet communications provide remote con trol program and monitor with 12 bit accuracy.
• Remote Analog Interface. User selec table 0-5V or 0-10V analog program ming and monitors.
• Field Strappable Parallel Operation. Up to 4 identical supplies may be oper ated in parallel with user configurable master and active current sharing.
• Zero Space Stacking. 2U rack mount supplies may be stacked with no space required between supplies
• Low Ripple. Ripple is less than 0.1% RMS of rated voltage at full load up to 1 MHz. Total ripple and noise is less 0.4% p-p of rated voltage up to 20 MHz.
• Constant Voltage/Constant Current Operation. Automatic crossover from constant-voltage to constant-current regulation provides protection against overloads, arcs, and short circuits.
• Constant Current/Current Trip. A rear panel switch allows selection of either current mode.
• Cooling. Forced air with high speed frictionless bearing technology fans. This reduces noise and extends fan life.
• Last Setting Memory. The unit stores power supply parameters at each AC turn-off sequence. Stored parameters are: Output Voltage Setting, Output Current Setting, OVP level, UVP level, Address and Baude Rate.
• Warranty. All power supplies are warranted for one year. A formal warranty statement is available.
