SERIE MPS

  • Entrada diferencial para programación de voltaje
  • Control RS-232/RS-485 opcional
  • Monitores y controles de voltaje y corriente
  • Alta estabilidad, ruido y rizo ultra bajos
  • Marca CE y certificado UL61010A-1

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.

También se proporciona como estándar una interfaz remota de usuario con todas las funciones a través de un conector del tipo D de 15 terminales y opcionalmente, también está disponible una interfaz serial RS-232 o RS-485. La tecnología de alto voltaje propia de Spellman en conjunto con los componentes de circuito de montaje superficial tiene como resultado un módulo compacto y ligero que está disponible como fuente de alimentación positiva o negativa y que es ideal para aplicaciones de OEM.
