WARNING
In order to prevent electric shock, use voltage to ground that is at or
less than the SELV* on the LOW side of the high-voltage input cords.
Although the LOW side of the high-voltage input cords is functionally
insulated from ground, there is no withstand voltage.
*: SELV (separated external low voltage): effective value of 30 V, peak
value of 42.4 V
1.2 Features
(1) Direct connection to the 3153
The 3930 can be directly connected to the 3153 AUTOMATIC
INSULATION/WITHSTANDING HiTESTER. Because the 3153 supplies
power to the 3930, no separate power supply is needed.
(2) Single mode and Multi-mode
The 3930 has two operation modes: single mode and multi-mode. Single
mode permits testing of eight channels using the one COM channel and
eight high-output channels. Multi-mode permits testing of four pairs of two
different high-output channels.
(3) Multiple channels
In single mode, the 3930 can test eight channels. In multi-mode, the 3930
can test four channel pairs. In addition, a unique ID can be set for each unit,
allowing a maximum of four 3930s to be connected to a single master unit.
(4) Output channel indicators
The LEDs on the front panel indicate the current mode and the channels that
are being output.
(5) Insulated design
The power supply, the high-voltage inputs and outputs, and the control input
connector signal wires are all functionally insulated.
(6) Signal level from 5 to 24 V
Devices ranging from general logic to a sequencer can be connected by
selecting the supply voltage for the control signal system.
(7) Safe design that avoids duplicate IDs
When multiple 3930s are connected, the unit can detect incorrect (duplicate)
ID settings. When a mistake is detected, all output is shut off.
