Enables control through TTL signals.

Uses a 6-pin connector; as with an output harness, power is output through the back of the power supply.

Sends signals such as Power Failure Detected (AC_FAIL) and Low Battery Voltage (BATT_LOW) to the computer and uses these signals to trigger OS automatic shutdown.

Following automatic OS shutdown, TTL sends a battery shutdown signal (SHUT_DOWN) to cut power, completely stopping output from the power source.

Note: TTL signals are exclusive to Nipron Co., Ltd. products. Their use requires compatible motherboard and/or interface design.
