Used, but clean, tested, and in good working condition. Includes the RS-232 digital programming interface option. The DMM is for testing only and not included.

The 1000 watt DC output power supplies provide low noise, precisely regulated, variable DC output. Typically they are used for bench and automated test equipment (ATE) applications. Each unit includes over voltage protection and thermal shutdown as standard features. Universal AC input allows you to use line voltages globally without resetting switches or adding options. Built-in power factor correction gives you full output power from low current/low voltage outlets, reduces power line interference, and allows you to meet international regulations. You can select from several remote control choices for either analog or digital control. For analog control, choose from standard analog control or optional 4-channel isolated programming. Digital control options include RS-232 control or GPIB programming. You can use the power supply on your benchtop or rack mounted; each supply occupies less than 3-1/2 in. (2 U) of vertical space. Whether you are powering batteries, development circuits, and magnet coils or running ATE systems, the power supply provides the precision and power that you need.
