The step-transformer type INA 6501 is a standard accessory for the Schaffner Modula 6000 instrumentation series and for the NSG3040/NSG3060. It provides a convenient means of reducing the incoming supply voltage by pre-set amounts. It is required for power quality testing (PQT) as per IEC/EN 61000-4-11 for voltage dips and under-voltages.
It is fitted with carrying handles as part of its overall good ergonomic design, which makes for ease of handling. Further, the unit may be used in any of three operating positions; laying or standing on a workbench, or for more permanent applications, it can be wall-mounted.
The few control elements are readily accessible on the front panel. An EUT power on/off switch with a power on indicator and a well-proportioned rotary switch to select the required voltage ensure easy and intuitive operation.
The unit has been designed for use in rugged industrial environments. Professional quality connectors ensure user safety, additional system protection is provided by a 16 A fuse located in the front panel.
