小型パワーモジュールのサプライヤーについて

現在、多くのオープン フレーム電源は 2 つの電力定格を提供しています。1 つは対流または伝導冷却を備え、もう 1 つは外部強制空気が適用されます。一部のアプリケーションでは、患者の快適性が重要な医療など、音響ノイズレベルを低くする必要があるため、ファンレス冷却が好まれます。これは、電源装置をその対流定格で動作させることによって達成できます。また、伝導冷却も可能な場合は、両方の組み合わせによって実現できます。

出力負荷が時間とともに大幅に変化する場合は、ピーク電力定格の電源を使用できる場合があります。これにより、より低出力の製品を選択できるようになり、対流冷却のピーク出力定格が強制空気連続定格と同じになることが多いため、コストを節約し、サイズを小さくすることができます。

たとえば、最新の病院用ベッドには電気モーターが取り付けられており、ベッドの角度を調整して患者が直立して座ることができるようにしたり、下部を持ち上げて脚を上げたりすることができます。これらのモーターは短時間しか作動しない場合があります。同じことが、歯科用椅子、赤ちゃん用の保温器、保育器にも当てはまります。
