The series of EAQ-MT AC sources have been developed for simulation and analysis of one or three phase line voltage, particularly for high power. Output voltage is infinitely variable between 1 and 100% of the nominal voltage and is being kept constant with a deviation of < 1%. The preset reference input can be reached with the potentiometer as well as via the optional interfaces. In 3 phase units the regulation is controlled by phase L1. The structure of the AC source EAQ-MT consists of a regulated ring transformer with isolation. The regulated ring transformer is operated through a DC motor. The set voltage is being kept constant at deviations of the line input voltage as well as at load variations at the output.

Analogue Indication

The EAQ-MT AC source has got six analog gauges for indication of voltage and current in each phase. Optionally, the source can be equipped with digital displays.

Adjustments

Voltage adjustments VAC are done through high quality 10-turn potentiometer.

Fuse Protection

Source are equipped input and output safety fuses. Optionally, the source can be equipped with automatic circuit breaker at the output. Manual adjustable overcurrent switching-off is also available. Switching-off the unit can be done through a power relay.

Analog Interface

Available as an option, the analogue interface enables user programming and reading of data via 0-5 VDC signal. Changing and checking modes are possible through digital TTL signals.
