Mecc Alte AVR SR7 SR7-2G
1.Mecc Alte AVR SR7
The SR-7 type voltage regulator is an advanced design electronic 5 Amp regulator that ensures excellent performance of the alternators while they are running and during starting. The regulator is equipped with a complete protection system against operation conditions that could be dangerous for the machine. The SR-7 regulator is suitable for being used with all Mecc Alte alternators and is standard supply for power outputs below 85 KVA, both three-phase and single phase.
2. Mecc Alte AVR SR7 Technical specification:
Input: The regulator is equipped with three differential sensing inputs (terminals 1-2, 3-4, 5-6);
Voltage precision: The voltage remains within ±1% of the pre-set value when passing from zero to full load
Protections: The UVR6 regulator is equipped with two protec-tion systems, and when they intervene the following. a) Delayed protection for overloads (yellow LED).b) Low speed protection (red LED).
Self-excitation: The regulator is equipped with a “starter” device that utilises the residual voltage of the machine for supply and excitation adjustment.
Usage field: The UVR6 can be used with all voltages from 80 to 480 Vac at 50 Hz.
