Fuente Integrada De Alimentacion De Triodo Para Emisión Termoiónica SEM
El EBM-TEGR es una solución integral que proporciona el alto voltaje requerido por el microscopio electrónico de barrido de emisión termoiónica (SEM) en un chasis montable en rack de 19".
La tecnología patentada de empaquetado y encapsulado de Spellman ofrece mejoras dramáticas en tamaño, costo y rendimiento en comparación con lo que ofrecen otras fuentes de alimentación SEM.
Esta unidad proporciona una fuente de acelerador altamente regulado, de bajo ruido y ultra estable programable hasta -30kV a 400uA. Esto, junto con los suministros de filamento flotante y rejilla referenciados al acelerador controlan el haz. La unidad también incluye salidas de alto voltaje para accionar el detector, que comprende PMT, centellador y salidas de colector aterrizado.
El control del cliente de este sistema de fuente de alimentación EBM-TEGR integrado se realiza a través de RS-232 o la interfaz RS-485 opcional. Se proporcionan cinco enclavamientos. La unidad tiene marcado CE y UKCA.
Especificaciones
(Ref. 128031-001 REV. B)
SPECIFICATIONS
Input Voltage:
100 to 264 Vac @2A max. 47 to 63Hz
Temperature:
Operating: 10°C to +45°C
Storage: -10°C to +70°C
Humidity:
0 to 90% RH, non-condensing
Interlocks:
Five interlocks are provided on a 9 pin D connector (see pinout details).
The EHT, Collector, Scintillator and PMT interlocks disable the corresponding outputs when open (the other outputs can be powered up).
The Vacuum interlock disables the gun supplies (EHT and heater) when open.
Front Panel Indicators:
POWER ON: Green LED
INTERLOCKS: Yellow LED indicates that all the interlocks are closed and the unit is able to generate high voltage.
HV ON: Yellow LED indicates that the high voltage EHT (Accelerator) Output is energized.
RS-232/RS-485: Yellow LED indicates when communications are taking place on the RS-232/RS-485 bus.
FAULT: Red LED indicates that an Error condition has occurred.
Input Power Connector::
I.E.C. 320 Receptacle with integral fuse
High Voltage Output Connectors:
Grid and Filament: Claymount CA1 type 03 (see drawing)
A mating cable assembly is available (see drawing and How To Order table)
Collector and PMT: BNC HT-MHV Receptacle Radiall R316553000
Scintillator: SHV Receptacle Radiall R317580000
Protection:
All outputs are protected from arcs in the load and continuous short circuit to ground and between each other.
- If the Beam Energy has more than 4 arcs in a 10 minutes period, unit will disable all outputs and sets all programs to zero.
- In case of an over temperature condition for greater than 100° C for ten seconds all outputs will be disabled.
- Over voltage, over current and internal communication issues are also monitored and trigger fault conditions.
- The unit reports fault or trip conditions through status flags. After a Trip occurs, the unit can be reset through software (digital interface) or power cycle.

Weight:
39.7 lbs. (18kg)
Regulatory Approvals:
Compliant to EEC Low Voltage Directive. UK Conformity Assessed. RoHS Compliant.
