140W Intelligent Automotive DC-DC ATX PC Power Supply
M2-ATX is an intelligent, high power, vehicle (car / boat / electric cart) 12V DC-DC ATX PC power supply designed for car pc and battery powered applications. Designed to provide power and to control the ON/OFF switch of a motherboard (car PC) based on ignition status, M2-ATX is a wide input (6 to 32V) vehicle battery operated ATX power supply capable of surviving tough vehicle engine cranks (down to 6V) as well as transient over-voltage situations. Just connect it to vehicle's battery and power up your PC!
Vehicle batteries can provide a limited amount of electricity to your devices. Even if your computer is completely OFF, a PC will still consume a few hundered milliwatts, needed to monitor PC ON/OFF status. When the computer (car pc) is in the suspend/sleep mode, it will consume even more power, because the RAM needs to be powered at all times. The power consumption in the suspend mode is few watts. No matter how big your car battery is, a PC will eventually drain your vehicle's battery in a matter of days.
While in deep sleep mode, M2-ATX 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, along with multiple timing schemes, small formfactor and very competitive price makes the M2-ATX the premier solution for dc-dc ATX vehicle / car PC power supply solutions.
Onboard Startup/Shutdown Controller
M2-ATX 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 becomes a traditional PC PSU with no ignition control (shudown controller bypassed) and it can be used in non-vehicle computer applications.
Dimensions and Compatability
The M2-ATX measures 1.77"(W)x6.31"(L) and is less than 1" high which makes it compatible with the Ampie enclosure and with most Casetronics and Morex enclosures and it is footprint compatible with the M1-ATX. The same version of microcode will run on both M1-ATX and M2-ATX.
Note: M2-ATX provides up to 8A on the 12V rail, making it ideal for operating most low power P4, P4-M, Celeron, ADM systems. Low power Geode and VIA processors (C3, C7) will work as well, leaving ample power for 12V or 5V peripherials (multiple 3.5" hard drives, CDROM, etc).
The M2-ATX Bundle comes with:
-140W M2-ATX-HV PSU
- 20 pin ATX cable extender plus HDD and Floppy power (9inch)
- Power input cable harness terminated in 0.25' fastons (12inch)
- 2 pin M/B on/off power ON control wire harness (9inch)
- 3 jumpers to control various power sequencing schemes
