Current response time:

8 Minutes 34 Seconds
  • Description: Power Supply
  • Weight: Approx 700 g
  • Footnotes: *1 Specifi ed with the rated input voltage (100 or 200 VAC) and 100% load applied. *2 Automatic recovery occurs after dropping. When output is interrupted, wait for 1 minute or longer after the input is turned off, and then turn on the input for recovery. *3 Output is cut off by an amplitude interrupting system. When output is interrupted, wait for 1 minute or longer after the input is turned off, and then turn on the input for recovery.
