Spellman MPD Series of High Voltage 10 Watt Modules
La serie MPD de Spellman es una familia de módulos de alto voltaje y alto rendimiento de 10 watts con voltajes de salida que van desde 1kV a 30kV.
La topología híbrida de Spellman de técnicas de conversión de energía lineal y de modo conmutado ofrece un ruido ultra bajo, excelente rendimiento de rizo y estabilidad, todo dentro de su huella compacta.
La serie MPD se puede controlar a través de interfaces analógicas o digitales, ambas proporcionadas a través de un conector estándar de tipo D de 15 pines.
En el modo analógico, la unidad cuenta con una entrada de amplificador diferencial para la señal de programación de voltaje para mejorar la inmunidad al ruido del sistema externo y abordar cualquier problema de compensación. En el modo digital, las interfaces RS-232 y RS-485 proporcionan características adicionales: control de corriente, indicadores de estado, operación de unidades múltiples (solo RS-485) y función wobbler.
La tecnología HV patentada de Spellman junto con los circuitos SMT dan como resultado un módulo ultracompacto y liviano, disponible como suministro positivo o negativo, que es ideal para aplicaciones OEM.
