Installing the Test System
Connecting to other signal terminals
You can use the following terminals as necessary.
AUX terminal
To construct a total test system that includes a LIN series line impedance network, apply
overheat protection signals (PCR CONTROL) from a LIN series to this terminal. The input
overheat protection signal is connected to the AUX terminals of the AC power supplies via the
PHASE IN terminal.
The LIN series is connected using the supplied control cable.
TRIG IN terminal
This is an exclusive input terminal for receiving signals from AC power supplies to transmit
trigger signals during voltage variation tests.
The SEQ TRIG OUT terminals of the AC power supplies are connected to the TRIG IN termi-
nal using BNC-BNC cables. Please provide your own cables.
This connection is required if you need to use trigger signals such as when monitoring the
trigger signals on an oscilloscope during voltage variation tests. During voltage-dip and short-
interruption tests, this product transmits trigger signals on its own, so this connection is not
necessary, but there is no problem if it is connected.
TRIG OUT terminal
This is an output terminal for transmitting trigger signals for starting and stopping voltage dips
and short interruptions and starting and stopping voltage variation.
• Trigger signal output: 0 V to +5 V (10 k Ω )
This signal is normally at high level (2.5 V or higher into a load resistance of 10 k Ω or
more) and is set to low level during trigger transmission (0.5 V or less).
• The trigger signal is activated from the SD009-PCR-LE Quick Immunity Sequencer 2
application software.
VOLTAGE MONITOR terminal
This is a signal output terminal for monitoring output voltage waveforms.
• Voltage monitor output: 1 V/100 V (±5 V MAX)
CURRENT MONITOR terminal
This is a signal output terminal for monitoring output current waveforms. The terminal was
designed mainly for monitoring the inrush current waveform flowing through the EUT. As
such, if this terminal is used to monitor minute current waveforms, the voltage signal level will
be low, and large waveform distortion or noise may appear in the signal.
• Current monitor output: 1 V/100 A (±5 V MAX)
Except for the AUX terminal, the metal parts around the terminals are at the same electric
potential and are connected to the internal circuit of the product. However, the terminals are
isolated from the INPUT terminal block, OUTPUT terminal block, and AC INPUT terminal
block.
