10W DC-DC High Voltage Power Supplies
La nueva serie PMS de Spellman es una familia de módulos de alto voltaje de 10 W que proporciona voltajes de salida que van de 1 kV a 30 kV.
La serie PMS es un conjunto de productos de alto desempeño diseñados con la topología híbrida de Spellman usando técnicas de conversión lineal y de conmutación de energía que suministran una alta eficiencia y bajo ruido. La serie MPS produce especificaciones de excelente desempeño de rizo y estabilidad en un dispositivo compacto. Adicionalmente, la serie MPS cuenta con la función estándar de entrada de amplificador diferencial para la señal de programación de voltaje, lo que proporciona inmunidad contra el ruido externo al sistema y se encarga de cualquier problema de desplazamiento. Alternativamente, la salida de voltaje puede predefinirse mediante un potenciómetro interno.
Las interfaces digitales RS-232 o RS-485 también están disponibles como opcionales; tanto los controles analógicos estándar como los digitales opcionales se proporcionan a través de un conector de tipo D de 15 pines.
