The ASX-220 Flameproof Alternator is designed to be a direct replacement for non-flameproof alternators used on diesel engines. Some adjustments to mounting brackets and belt tensioning link may be necessary. The alternator rear cover can be rotated to provide alternate cable entry positions. In the case of fixed speed applications the pulley drive should be arranged to give a continuous alternator speed of between 5,000 rpm and 7,000 rpm. In the case of variable speed applications the pulley ratio should be selected to give an alternator speed of 2,000 to 2,500 rpm at the engine low idle. This typically equates to a normal operating alternator speed range of about 3,500 rpm to 8,000 rpm. The maximum output demand for the ASX-220 alternator should not exceed 50 amps.
A wide range of pulleys are available for the ASX-220 alternator. Some models are listed below. For pulley selection please refer to the ASX-220 data sheet.
