Weight: FRONT PANEL CONTROLS (standard versions) Voltage setting: Current setting: Overvoltage setting: Output On/Off: Via single rotary controls for coarse and fine control. Via single turn semi-logarithmic rotary control. Via screwdriver adjustable preset potentiometer. Via large paddle lever switch. FRONT PANEL CONTROLS (P versions) Voltage setting: Current setting: Overvoltage setting: Output On/Off: Direct keyboard entry or quasi-analogue rotary control. Direct keyboard entry or quasi-analogue rotary control. Direct keyboard entry. Push button with dual indicator lamps. Note: all voltage and current levels set via the keyboard are displayed on a separate 0.3" 4 digit display. This entry preview system ensures that the user can observe the value entered before it is effected thus avoiding possible error. The display is also used for setting additional functions and for displaying watts. Additional keyboard functions: OUTPUT SPECIFICATIONS Constant voltage or constant current with automatic crossover.
