MSA系列是紧凑的可安装在印刷电路板(PCB)上高压电源模块。
MSA 系列是紧凑型印刷电路板可安装 (PCB) 高压电源模块，从1kV 至 3kV，可选正的或负的输出极性。MSA 系列的特点是 0-10Vdc 可变电压编程等于 0-100% 额定输出电压。提供一个电压监测，0-10Vdc 等于 0-100% 的额定输出电压。此外，状态信号和使能信号提供对电源的简单控制。所有的电源都有内置的故障保护。
MSA 系列适用于需要紧凑型高性能 PCB 可安装电源的场合，比如驱动质谱仪中的电子倍增器。铝制外壳有助于屏蔽此单元减少辐射噪声。

MSA SELECTION TABLE
| Model | Output Voltage | Output Current | Ripple (Vpp) |
|---|---|---|---|
| MSA1*24 | 0-1kV | 0-900μA | 30mV |
| MSA2*24 | 0-2kV | 0-450μA | 40mV |
| MSA3*24 | 0-3kV | 0-300μA | 50mV |
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
