質量分析用電源装置

スペルマンのMI1.5PN24は、非常に安定化された高性能DC-DCコンバーターで、フローティング1.5kV＠6.5mA出力を備え、動作範囲は300V～1500Vです。出力は分離されており、これにより+Ve,-Ve、または切り替え可能な極性の負荷へ接続が可能になり、パルス電流が所定のパス内に含まれるようになり、ノイズと干渉の兆候が減少します。MI1.5PN24の低出力リップル仕様により、質量分析アプリケーションのパルサーでの使用に最適です。このモジュールはシールドされた金属筐体にパッケージされており、高電圧出力は2本のキャプティブケーブルを介して供給されます。MI1.5PN24は、大型で高品質の容量と堅牢な出力ネットワークを備えているため、大幅な電圧降下やユニット回路の損傷なしに、高エネルギーのパルス負荷に継続的に電力を供給することができます。ユニットには、リモート0-10Vdc = 0-100％定格電圧プログラミングと電圧モニターがあります。TTL準拠のイネーブル信号により、高電圧出力を簡単に制御できます。
