FUENTE DE ALIMENTACIÓN DE ESPECTROMETRIA DE MASAS

El MI1.5PN24 de Spellman es un convertidor DC-CC bien regulado y de alto rendimiento con una salida flotante de 1.5 kV a 6.5 mA, tiene un rango operativo de 300V-1500V. La salida está aislada; esto permite la conexión a cargas de +Ve, -Ve o polaridad conmutable y para que las corrientes de pulso estén contenidas dentro de los trazados prescritos, reduciendo ruido e interferencia. La baja especificación de rizo de salida de la ML1.5PN24 la hace ideal para su uso con pulsadores en aplicaciones de espectrometría de masas.

Polarity:

Positive or negative, isolated to 1.5kV 

Load Current:

6.5mA, maximum

Power:

9.75 watts, maximum

Regulation:

Line: <0.5% for line change of ±10%

Load: <0.1% for zero to full load

Stability:

Better than 300ppm/hour after 1 hour warm up. 100ppm/hour after 2 hour warm up at constant operating conditions. Typically, 50ppm/hour after 1 hour and 15ppm/hour after 2 hours.

Ripple:

<75mV peak to peak at full load when either end is grounded. 

Output Current Limit:

The module will have an output current limit of 9mA. The module is capable of withstanding an indefinite short circuit or overload on its output and will recover automatically once the short circuit is removed.

Supply Voltage Dynamic Rejection:

< than 20mV for an input step of 1 volt (within the range of +24Vdc, +10%/-2%)

Setting Time:

500 milliseconds maximum under all conditions.
