MSA
MSAシリーズは、コンパクトなプリント基板実装可能（PCB）高圧電源モジュールで、1kVから3kV、そして正または負の出力極性がございます。またMSAシリーズは、定格出力電圧の0〜100％に相当する0〜10Vdcの可変電圧プログラミングを備えています。0-10Vdcが定格出力電圧の0-100％に等しい電圧モニターが提供されます。さらに、ステータス信号とイネーブル信号により、電源を簡単に制御できます。すべてのユニットには、障害状態に対する保護が組み込まれています。
MSAシリーズは、質量分析計の電子増倍管の駆動など、コンパクトで高性能なPCBにマウント可能な電源が必要な一般的な使用を目的としています。アルミニウム製の筐体はユニットのシールドに役立ち、放射ノイズを低減します。

1) Replace the * with “P” for positive output polarity and “N” for negative output polarity.
2) The ripple figure includes random non switch related noise, noise related to the oscillator, switching and feedback control circuitry and noise associated with the rectified primary switching frequency.
LOW VOLTAGE SIGNAL PINS FOR POWER AND CONTROL
| PIN | SIGNAL | LEVEL | SIGNAL PARAMETERS |
|---|---|---|---|
| 1 | Enable | TTL | Enable = Low (≤1.2V). Disable = High (≥2.4V), when Enable pin is NC, 10kΩ pull up to +5V ±10% |
| 2 | Status | 0V/5V | OK = 11kΩ pull up to +5.1V ±10%. Fault = ≤0.1V, Zout = 1kΩ |
| 3 | Voltage Program | 0-10V | 0 to +10Vdc = 0 to 100% rated output voltage, Accuracy ≈ ±1%. Zin = 10kΩ |
| 4 | Voltage Monitor | 0-10V | 0 to +10Vdc = 0 to 100% rated output voltage, Accuracy = ±2%. Zout = 20kΩ |
| 5 | Input Voltage | 24Vdc | Power Input |
| 6* | Signal Ground | 0V | Ground reference for control and monitoring signals |
| 7* | Power Ground | 0V | Power Return |
To reset the unit after a fault condition, Pin1 (Enable) must be set high for at least 10 seconds
* pins 6 & 7 are linked internally
