CONVERTIDOR DE DC A DC DE ALTO VOLTAJE

El MCP4 de Spellman es un convertidor DC-DC de alto rendimiento bien regulado que cuenta con una salida flotante de 4kV a 600uA, aislada a 15 kV. La especificación baja de rizo de salida y la alta estabilidad de la MCP4 la hacen ideal para su uso con detectores en aplicaciones de espectrometría de masas tales como: multiplicadores de electrones (EM), detectores de placas de microcanal (MCP) y multiplicadores de electrones de canal. Este módulo está empaquetado en una carcasa metálica blindada y la salida de alto voltaje se proporciona a través de dos cables coaxiales blindados cautivos de un metro de largo. La unidad tiene programación remota de voltaje de 0-10Vdc = 0-100% del voltaje de salida y monitor de voltaje. Una señal de habilitado compatible con TTL proporciona un control sencillo de la salida de alto voltaje. Esta unidad ha sido diseñada específicamente para minimizar la interferencia con la fuente de alta tensión sobre la que flota. La MCP4 se puede personalizar para satisfacer los requisitos del OEM.

Aplicaciones típicas:

• Detectores de espectrometría de masas.
• Placas de microcanal
• Multiplicadores de electrones.
• Multiplicadores de electrones. de canal.

Especificaciones

^{(Ref. 128152-001 REV. B)}

Input Voltage:

+24Vdc, ±5%

Input Current:

700 mA maximum

Output Voltage:

0 to 4kV, continuously variable over the entire output range

Output Current:

600uA maximum

Current Limit:

Polarity:

Reversible polarity inherent by design

Isolation Voltage:

Up to 15kV total to ground.
Note: When the unit output is set to zero and no load is connected: If the reference supply is positive (up to +15kV), +VE will always be less than 100V with respect to -VE. If the reference supply is negative (up to -15kV), a 47MΩ pre-load resistor fitted within the MCP4 limits +VE (with respect to -VE) to ≤ 1400V

Line Regulation:

50ppm for a ±5% line change

Load Regulation:

300ppm for a 10% to 100% load change

Voltage Programming:

0 to 10 volt corresponds to 0 to 100% of rated output voltage

Voltage Monitor:

0 to 10 volts corresponds to 0 to 100% of rated output voltage. Accuracy ±1%. Iout=300μA maximum
