Current Limiting 0 to 500 milliamperes continuously adjustable by a front panel control. A front panel push button permits easy adjustment without shorting the output terminals.
Output Terminals
Front Panel
|
Three insulated binding posts for positive
|
|
output, negative output, and chassis ground
|
Rear Panel Screw terminals on a molded barrier block for positive output, negative output, chassis
ground, remote voltage programming and remote sensing.
Remote Sensing
|
Two terminals are provided on a rear panel
|
barrier block for remote sensing of the
voltage at the load.
