※Since there is no manufacturer, it will be handed over as is. CSE isolation regulator. AC is converted to DC, stored in a capacitor, and then the sine wave is amplified analogically. It is a low impedance constant voltage power supply suitable for load devices with high power consumption. The rated output is 500W, and the output frequency can be changed to 50, 60, 80, 100, and 120 Hz, and it also has a soft start function to reduce through lines and inrush current, so it seems useful. The exterior, paint deterioration, dullness, small scratches, etc. can be seen (Kobayashi Hitoshi)
