Parameter
Remote On/Off Signal Interface
(VI = 0 V to 36 V; open collector or equivalent compatible;
signal referenced to VI(–) terminal; see Figure 11 and
Feature Descriptions.):
JFCxxxC1 Preferred Logic:
Both Primary and Secondary Referenced Remote On/Off:
Logic Low—Module On
Logic High—Module Off
JFCxxxC Optional Logic (optional for primary referenced
remote on/off only):
Primary Referenced Remote On/Off:
Logic Low—Module Off
Logic High—Module On
Secondary Referenced Remote On/Off:
Logic Low—Module On
Logic High—Module Off
Logic Low:
Ion/off = 1.0 mA
Von/off = 0.0 V
Logic High (open collector):
Ion/off = 0.0 µA
Leakage Current
Turn-on Time
(IO = 80% of IO, max; VO within ±1% of steady state)
Output Voltage Adjustment (See Feature Descriptions.):
Output Voltage Remote-sense Range
Output Voltage Set-point Adjustment (trim) Range
(Note: Ensure that the combination of remote-sense and trim
do not exceed 15.5 V on the output.)
