  • *1 Specifications differ when options are set. Please contact the manufacturer support center for details.
  • *2 It is a value on a measuring board with a 22 mF capacitor attached to the point at 150 mm from the output terminal. (By 20 MHz oscilloscope or ripple noise meter (KEISOKUGIKEN: RM-103 equivalent)).
  • *3 Drift over time is at ambient temperature of 25°C. It is a change during 30 minutes to 8 hours after applying the input voltage at the rated input/output.
  • *4 Output derating is required. Please contact the manufacturer support center for use with DC.
  • *5The values in (parentheses) indicate the peak values. Please refrain from continuous use at peak currents.
    It may destroy the internal elements.
    There is a limit to the peak current (time / duty).
  • *6 "RC" is applied when adding a remote control (option).
  • *7 In case of dynamic fluctuation, the specification may not be satisfied.
  • *8 Please contact the manufacturer support center for other classes.
  • * Please avoid using it in an overloaded state or outside the specification range, as it may damage the internal elements.
  • * Parallel operation is not possible.
  • * Derating is required if the chassis and cover are included.
  • * Sound noise may be heard from the power supply when used for pulse load.

Development story

 

By using the same external shape and mounting as those of the 100 V AC (85 to 132 V) LGA series (output power 50 to 240 W), it is easy to replace even if the customer urgently requests 200 V AC compatibility.
In addition, by expanding the lineup with models from 10 to 305 W as a circuit board starter power supply, even if using multiple units, it is possible to arrange them in the same series.
