The automatic step transformer type INA 6502 is a standard accessor y for the Teseq Modula 6000 instrumentation series. It enables the ac power supply voltage, which is fed to the EUT, to be set to 0%, 40%, 70% or 80% of UINunder program control.

The INA 6502 complies with the requirements of IEC/EN 61000-4-11(2004) for voltage dips and under-

voltages. A large number of product standard speciﬁ cations can be fully met as they do not ask for

continuous and arbitrary voltage variations.

The device is connected to the Modula system via the system cable and is fully embedded in the

conﬁ guration management concept, the software control and the report mechanism.

The voltage steps, UVAR, are programmed as a percentage of the power line voltage using either the mobile handheld controller or by means of WinModula. The updated version of WinModula includes preprogrammed tests using the INA 6502 for the basic standard, the generic standards and a considerable number of product standards.

A circuit breaker is incorporated into the housing of the INA 6502. This allows the on/off switching of the

power to the EUT at any moment via the user interface or automatically under program control. A remote EUT-off hardware switch to cut power and high voltage pulse generation is available as an option.

The step transformer is designed into a sturdy aluminum housing ﬁ tted with convenient handles. In

applications the INA 6502 can be used in any position and may even be placed under the test bench if the space on the set-up becomes limited.
