M4-ATX
is an intelligent, high power, vehicle (car / boat / electric cart)
DC-DC ATX PC power supply designed for use with car pc or general
purpose battery powered applications. Designed to provide power and to
control the motherboards's ON/OFF switch based on ignition status,
M4-ATX-HV is a wide input (6 to 34V) vehicle / car / battery operated
ATX power supply capable of surviving tough car engine cranks (down to
6V) as well as transient over-voltage situations.
Connect it to your car / boat / RV / solar battery and power up your PC!
By using Patent Pending HyperWatt[TM] technologies, M4-AT-HV packs an
impressive amount of power relative with its small footprint. M4-ATX-HV
has several key advantages over traditional power supplies:
- Programmable shutdown / sleep modes via optional serial cable.
- Fits any motherboard equipped with a 20 or 24pin ATX connector.
- 100% silent, fanless, no moving parts.
- Operates from 6-34V, multi-chemistry batteries supported.
- Highly efficient design, does not produce a lot of heat.
- Works with any Intel Core Duo as well as all VIA or AMD processors.
Firmware on the M4-ATX-HV can be changed to accommodate different behaviours. OEM / reseller integration is welcome.
