Slew Rate
Theory
The PSW has selectable slew rates for CC and
CV mode. This gives the PSW power supply
the ability to limit the current/voltage draw of
the power supply. Slew rate settings are
divided into High Speed Priority and Slew
Rate Priority. High Speed Priority mode
disables slew rate settings for CC or CV mode.
Slew Rate Priority mode allows for user
adjustable slew rates for CC or CV mode. The
rising and falling slew rate can be set
independently.

Bleeder Control
Background
The PSW DC power supplies employ a bleed
resistor in parallel with the output terminals.

resistor
Bleed resistors are designed to dissipate the
power from the power supply filter capacitors
