囲第１項記載の交流電源装置のフアン回路。[Claims for Utility Model Registration] (1) Equipped with an AC fan that cools the device with forced air, power is always supplied from the inverter circuit to the load, and when the inverter circuit stops, power is supplied directly from the commercial AC power source to the load. In the fan circuit of the AC power supply device configured as shown in FIG. When the circuit stops, the AC fan is switched to be operated by the commercial AC power supply, and when the temperature inside the device falls below a certain value, the AC fan operation by the commercial AC power supply is stopped. AC power supply fan circuit. (2) A request for utility model registration characterized in that a thermostat contact that closes when the concentration in the device exceeds a certain value is connected in series with the contact that is switched when the inverter circuit stops. A fan circuit of an AC power supply device according to scope 1.
