ホットスイッチ可能、極性反転可能電源
スペルマンのMXRシリーズは、良好に制御された高性能DCDCコンバーターです。MXRの低リップル仕様は、質量分析法と電子顕微鏡に理想的です。MXR20の定格は20kV @300uA、MXR30の定格は30kV @ 300uAです。両製品ともシールドされた金属ケースに収められており、アナログまたはRS-232デジタル制御オプションのいずれかでご利用になれます。これらの装置には出力極性反転を制御するための論理信号入力を備えています。電圧・極性・電流モニターと合わせて、デジタルバージョンはオプトアイソレートされたインターロック入力（HVイネーブルインヒビット）が提供されます。MXRシリーズは、OEM要件に適合するためのカスタム化が簡単で、電流制御を実装可能で、リップル性能が改善されている上、より高い電圧と電流性能を備えます。
典型的な用途:
- 質量分析
- 電子顕微鏡
- キャピラリー電気泳動
- 静電印刷
