The ASM150 is a user friendly, solid-state, automatic engine controller. It provides basic automatic start/stop capabilities plus other features found on more sophisticated and expensive controllers.

The ASM150 operates from 12 or 24 volt battery. It includes features such as selectable crank and rest cycles, sensing circuit for crank disconnect and overspeed, overcrank, and recrank protection on false starts. Four LEDs indicate first-out shutdown for: low pressure, high temperature, overcrank and overspeed. A fifth LED indicates engine running.

Advanced microprocessor circuitry gives the ASM150 high reliability and flexibility.

The ASM150 is compact and housed in a corrosion-resistant case. It mounts flush in a panel and requires very little room. Ideal for small generator or engine panels.
