The DP034 is an ATX PSU designed to supply a low power consumption PCs from a single 12V power source. The DP034 is direct plug-in to the motherboard, but cables are not available if direct-plug-in to the motherboard is not possible. The DP034 is very similar to DP031, DP032, DP033 PSU but is designed for Intel D410PT and Intel D510MO motherboards. NOTE that the DP034 does not have a regulated +12 Volt output, but simply passes the 12 Volts of the input supply voltage through to the motherboard. This makes it difficult to use for automotive applications. The wide input range unit is the DP022, which has an input range of 10 to 19 Volts. If you need regulated 12 Volts, then you should choose the DP022.
