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 307 W as a circuit board starter power supply, even if using multiple units, it is possible to arrange them in the same series.
