  • *1It 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)). Since it has a built-in power reduction function during standby and the internal switch element is operated intermittently, the ripple and ripple noise specifications differ at a load factor of Io = 0 to 35%.
  • *2 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.
  • *3 Output derating is required. Please contact the manufacturer support center for use with DC.
  • *4 When using multiple units, please contact the manufacturer support center as they may not comply with the regulations.
  • *5 In case of dynamic fluctuation, the specifications may not be satisfied.
  • *6 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 306 W as a circuit board starter power supply, even if using multiple units, it is possible to arrange them in the same series.
