FUENTE DE ALIMENTACIÓN DE INVERSIÓN DE POLARIDAD CONMUTABLE SIN DESCONEXIÓN

La serie MXR de Spellman son convertidores DC-DC de alto rendimiento bien regulados. La especificación de baja ondulación del MXR lo hace ideal para espectrometría de masas y microscopios de electrones. El MXR20 tiene una especificación de 20kV @ 300uA y el MXR30 tiene una especificación de 30kV @ 300uA. Ambos son empaquetados en una carcasa metálica blindada y están disponibles en opciones de control analógico o digital RS232. Estas unidades cuentan con una entrada de señal lógica para controlar la inversión de la polaridad de salida. Se proporcionan monitores de voltaje, polaridad y corriente. La versión digital también proporciona una entrada opto aislada de interlock (Habilitar HV/Deshabilitar). Fácilmente personalizada para cumplir con los requisitos del OEM, la serie MXR se puede proporcionar con control de corriente, rendimiento de ondulación mejorado y capacidades de voltaje y corriente más altas.

ROHS 200295EC compliant
