The CPX400 Series - Single and Dual output PowerFlex Laboratory DC Power Supplies - 420 or 840 watts

The individual DC output switches allows you to set up voltage and current levels before you connect to the load.

Surprisingly, many laboratory power supplies lack this basic feature, and require you to use the AC power switch for connection and disconnection.
 

For dual output models, the Synchronous On/Off button is in addition to the individual switches for each output, and allows both outputs to be turned on or off synchronously by a single button press.

Synchronous switching of the outputs is of increasing importance for circuitry which can be damaged if one voltage rail is present without the other.
 

When the output is on, the meters show the actual voltage and current.

Pressing the View V/I Settings button enables the limit settings to be checked and adjusted at any time.
