The automated step transformer type INA 6502 is a standard accessory for
the Teseq NSG 3000 instrumentation series. It provides a convenient means
of reducing the incoming supply voltage by pre-set amounts. It is required for
power quality testing (PQT) and is fully compliant with the latest revision of IEC
61000-4-11.
Its control is fully automatic, driven from the NSG 3000 master controller, using
the touch screen interface or the WIN 3000 remote control software. Once
detected, the functions offered by the INA 6502 are available in the interface or
software. So the settings 0 - 40% - 70 - 80% will appear, as well as the possibility
to switch the EUT power ON/OFF.
The INA 6502 is fi tted with carrying handles as part of its overall excellent
ergonomic design, which allows easy handling. Further, the unit may be used in
any of three operating positions; laying or standing on a workbench. For more
permanent applications, it can be even wall-mounted.
The unit has been designed for use in rugged industrial environments. High
quality connectors ensure user safety, additional system protection is provided
by a 16 A fuse located in the top panel.
Thanks to the provision of an 80% voltage position and to the large over current
capabilities the step transformer is fully compliant with the latest requirements
called for in IEC 61000-4-11 standard.

For proper operation of the plug and play detection
mechanisms it is strongly recommended to power on
fi rst the INA 6502 accessory and then the NSG main
frame.
