Zusammenfassung: | PROBLEM TO BE SOLVED: To obtain a power current controlling device capable of being operated at current as great as possible by moving a point for controlling current with ambient temperature of a breaker. SOLUTION: A power current controlling device is constituted of a current detection device 6 provided in this power circuit, a priority setting device 14 operated at upper limited value of gross current in accordance with capacity of a breaker 2 and setting gross current priority, an ambient temperature detection device 13 for detecting the ambient temperature of the breaker 2, an operating frequency correcting device 17 for correcting an operating frequency of a compressor 7 and an output circuit 19 for controlling an air conditioner 3. By the constitution, margin between breaker and operating current is reduced to make it possible to operate load at great input current. |
