MSA
La serie MSA es un módulo de fuente de alimentación compacto montado en una placa de circuito impreso de alto voltaje (PCB) disponible de 1kV a 3kV con una polaridad de salida positiva o negativa. La serie MSA cuenta con una programación de voltaje variable de 0-10Vdc que equivale al 0-100% del voltaje de salida nominal. Se proporciona un monitor de voltaje donde 0-10Vdc es igual a 0-100% de voltaje de salida nominal. Además, una señal de estado y una señal de activación proporcionan un control simple de la fuente de alimentación. Todas las unidades tienen protección incorporada contra condiciones de falla.
La serie MSA está diseñada para uso general donde se requiere una fuente de alimentación PCB compacta y montable de alto rendimiento, como manejar un multiplicador de electrones en un espectrómetro de masas. La carcasa de aluminio ayuda a proteger la unidad reduciendo el ruido radiado.
Aplicaciones típicas:
- Tubos fotomultiplicadores
- Multiplicador de electrones
- Espectrometría de masas
- Lentes electrostáticas
- Instrumentos nucleares

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
