Trigger In/Out function could be turned on or off by CONFIGURE
setting of PEL-3000E. The Trigger Input can be set the delay time
while the Trigger Out Pulse Width can be set as well.
The trigger output signal is generated every time a switching
operation is performed such as Dynamic mode or Fast/Normal
sequence is executed when the trig out parameter is enabled.
The trigger output signal from TRIG OUT BNC is a 4.5V pulse
of at least 2us with an impedance of 500ohm. The common
The TRIG IN BNC on the rear panel is used to resume a
sequence after a pause. This action is useful to synchronize
the execution of a sequence with another device. To resume
a pause sequence, apply a high signal for 10us or more. The
TRIG IN BNC is pulled down to earth internally using a
100Kohm resistor.
potential is connected to the chassis potential. The signal
threshold level is TTL.
The PEL-3000E series provides the external analog
channel control function, which allows users to
connect J1 connectors on the rear panel to input
voltage or to connect resistance to control electronic
load operation. Users can integrate this function into
test system and utilize signals generated from the
test system to control PEL-3000E.
The PEL-3000E series provides many protective functions including
over current protection (OCP), over voltage protection (OVP),
over power protection (OPP), over temperature protection (OTP)
and under voltage protection (UVP). Except for OTP, all thresholds

of protective functions are adjustable. When protective function is
activated, electronic load will send out warning signal and terminate
operation. Other than protective functions, Limit function can also
be utilized to maintain electronic load in operation at a preset value.
