Spellman MPD Series of High Voltage 10 Watt Modules
La nueva serie MPD de Spellman es una familia de módulos de 10 watts de alta tensión que proporcionan voltajes de salida que van desde 2.5kV a 20kV.
La serie MPD son productos de alto rendimiento diseñados con la topología híbrida de Spellman de técnicas de conversión de potencia lineal y de modo de conmutación que ofrecen menos ruido con mayor eficiencia. La serie MPD produce excelentes especificaciones de rendimiento de ondulación y estabilidad a partir de un espacio compacto. La serie MPD cuenta con una entrada de amplificador diferencial para la señal de programación de voltaje para mejorar la inmunidad del ruido externo del sistema y abordar cualquier problema de compensación.
Se proporciona una interfaz de usuario remota con todas las funciones a través de un conector de tipo D de 15 pines, así como una interfaz serie RS-232/RS-485. La unidad puede ser analógica completa o digital completo definido por los enlaces de conector de interfaz.
La tecnología HV patentada de Spellman junto con los circuitos SMT da como resultado un módulo ultra compacto y ligero que está disponible como un suministro positivo o negativo que es ideal para aplicaciones OEM.
