PURPOSE:To perform power interruption retreat processing optimal for a load by providing reports of measured voltage value, duration of power interruption and operating condition, i.e., commercial power supply or inverter operation, upon request by the load. CONSTITUTION:A load unit receives a power interruption detection report and interrogates power recovery information through communication. An RS 232C replies a load (m) with information obtained from a built-in power interruption duration counter or a measured voltage (i) of battery or a power interruption detection signal (i). Consequently, the load (m) can proceed a power interruption process conforming to the state of an uninterruptible power supply and upon finish of processing, an inverter stop command is delivered to stop inverter operation based on an inverter stop signal (k). |
