Features
Amplifier Input
Athree pin input connector that can be
configuredfor inverting, noninverting,or
differential amplification.
Digital Enable
Aninput providing aconnectionfor aTTL
compatiblesignal to turn on and off the
high-voltage output. ATTL high (or open)
turns offthe high-voltage output. ATTL
low turns on the high-voltage output.
Response Adjust
Agraduated one-turn potentiometer used
tooptimize the AC response ofthe
Model 609E-6.
Trip/Limit
Aswitch selectseither aCurrent Trip
mode or CurrentLimitmode. Agraduated
one-turnpotentiometer is used to adjust
the current trip/limitvalue from
0to 20 mA.
Out Of Regulation Indicator
Anindicator will illuminate whenthe
Model 609E-6 fails to produce the
required high-voltage output such as
during currentlimit.
Trip Status
Anindicator will illuminate and theTrip
Monitor BNC connector will provide a
TTL low when the high-voltage output is
disabled due to theoutput current
exceeding the current triplevel.
