Frequently asked questions

The 'HARD-OFF' setting allows you to control how long the 5VSB rail remains active after the system is shut down. This helps to conserve battery power and prevent deep discharge situations. You can choose from various settings ranging from a short delay to 'NEVER,' which keeps the 5VSB rail always active.

The 'AutoLatch' feature is active for the first 60 seconds after ignition is turned on. It locks the ignition in the ON position for that duration, ensuring the operating system has enough time to boot properly. This prevents disk drive corruption or system hangs.

The 'UPS mode' refers to a configuration where the M2-ATX-HV acts as an uninterruptible power supply (UPS). In this mode, the unit can power your PC even if the battery voltage drops, providing a seamless transition between battery and external power sources.

The M2-ATX-HV features an 'anti-thump' control that keeps the amp off while the PC starts. You can activate this feature by connecting J6 to the amplifier's remote control pins.

The maximum output currents are as follows: 5V: 6A, 3.3V: 6A, 5VSB: 1.5A, -12V: 0.15A, and 12V: 7A. Please note that the 12V rail current may vary depending on the input voltage and operating conditions.
