Turn-on Delay

Turn-on Rise

Turn-off Delay

Turn-off Fall

Turn-on delay is a period from when the ON command is issued by the ON/OFF control (via the ON/OFF1

pin or PMBus communication) until output voltage begins increasing. (See the figure below).

Turn-off delay is a period from when the OFF command is issued by the ON/OFF control (via the ON/OFF1

pin or PMBus communication) until output voltage begins decreasing. (See the figure below).

Turn-on Rise and Turn-off Fall are not retained when the output voltage setting is changed. Please reset

Turn-on Rise and Turn-off Fall after changing the output voltage setting.

There is a delay of 25ms typ. until the turn-on sequence begins after the input. (See the figure below).

Each setting of the sequence features can be configured via PMBus communication. However, turn-on rise

may differ from the preset time depending on load capacity.
