M2-ATX-HV 140W 6-32v Wide Input Intelligent Automotive DC-DC Power Supply The M2-ATX-HV is an intelligent, high power, vehicle (car / boat / electric cart) DC-DC ATX power supply designed for use with car pc or general purpose battery powered applications. Designed to provide power and to control the motherboard's ON/OFF switch based on ignition status, The M2-ATX is a wide input (6 to 32V) vehicle / car / battery operated ATX power supply capable of surviving tough car engine cranks (down to 6V) as well as transient over-voltage situations. M2-ATX-HV has 8 user selectable microcontroller driven timing modes, allowing you to choose up to 8 ignition/shutdown car pc timing schemes via a built-in shutdown controller. By removing all user-selectable jumpers, M2-ATX-HV becomes a traditional PC PSU with no ignition control (shutdown controller bypassed) and it can be used in non-vehicle computer applications. While in deep sleep mode, M2-ATX-HV constantly monitors your car battery voltage levels, preventing deep discharge situations by automatically shutting down (using a built-in shutdown controller) until battery levels reach safe levels again. No more dead car batteries, no more computer resets during engine cranks.
