Portable, simple to configure and use, the 100A/E mk3 gives maintenance and commissioning engineers all of the functionality they need for generating variable secondary current.

The 100A/E features 8 right current input in steps from 0.1A to as high as 200A. Voltage output can be set up to 500V (AC) or 250V (DC). This flexible generation system gives the engineer the ability to generate specific current at different levels, ensuring that the system can be used with a wide variety of secondary protectives.

Both the current and voltage outputs are independently controlled/metered for fine control. The system has two large analogue displays and includes an additional four range CT which extends the ammeters range down to 0 to 100mA.

The 100A/E’s timing system is designed with flexibility in mind; it features four modes of operation, two contact inputs and will automatically select normally open/closed contacts to ensure accurate timing measurements.

This system comes as standard in a robust carrying case with protective  cover and fold-away handles for easier transportation.
