The R120 AVR is a compact 153×105×47 mm unit capable of regulating voltage within ±1% RMS under ±4% engine governing conditions, with 20 A continuous output and soft-start protection. Its jumper-selectable sensing voltage (190–240 VAC) and under-frequency roll-off make it ideal for 3-phase alternator regulation.
Made from cast aluminum, it functions reliably from –40 °C to 65 °C and stores safely up to 85 °C, delivering 95 VDC excitation at full load. Rated for monthly production volumes into the tens of thousands, it is CE/ISO compliant for global distribution.
Suited for alternators from brands like Stamford, this AVR stabilizes generator output during fluctuating loads. Its under-frequency protection and LED status indication simplify diagnostics during maintenance.
