IMPORTANTI PRECAUZIONI DI SICUREZZA

SICUREZZA

QUESTO ALIMENTATORE GENERA TENSIONI CHE SONO PERICOLOSE E

POTREBBERO ESSERE MORTALI.

PONI ESTREMA CAUTELA QUANDO OPERI CON QUESO APPARECCHIO.

Gli alimentatori ad alta tensione devono sempre essere collegati ad un impianto di terra.

Non toccare le connessioni a meno che l’apparecchio sia stato spento e la capacità interna

del carico e dell’alimentatore stesso siano scariche.

Attendere cinque minuti per permettere la scarica della capacità interna dell’alimentatore

ad alta tensione.

Non mettere a terra il proprio corpo oppure operare in ambienti bagnati o saturi d’umidità.

SICUREZZA NELLA MANUTENZIONE.

Manutenzione potrebbe essere richiesta, rimuovendo la copertura con apparecchio

acceso.

La manutenzione deve essere svolta da personale qualificato, coscio dei rischi elettrici.

Attenzione alle AVVERTENZE contenute nel manuale, che richiamano all’attenzione ai

rischi quando si opera con tali unità e che potrebbero causare possibili ferite o morte.

Le note di CAUTELA contenute nel manuale, indicano le procedure da seguire per evitare

possibili danni all’apparecchio.

1.1 XRB011 DESCRIPTION

The XRB011 MONOBLOCKis a complete integrated system consisting of a high voltage power supply

(HVPS), filament supply, X-ray tube and oil encapsulant which provide the required high voltage insulation in

one compact enclosure. The combination of proprietary control system and protection circuitry enables the

supplies to operate under arcing and extreme transient conditions without damage or interruptions. Additional

advantages are the elimination of high voltage cables and extremely low leakage X-ray radiation.

The XRB011 incorporates local and remote programming, monitoring, and fault indicators including safety

interlock. The X-ray source is a sealed unit containing a HVPS and an X-ray tube. The insulating oil provides

electrical insulation for the high voltage sections of the power supply and the X-ray tube in a sealed tank. The

oil also functions as a coolant to carry heat away from the tube. Convection cooling augmented by customer

provided minimum 50cfm external fan is required for the 50W option. A rubber bellows in the tank of the X-ray

source compensates for the expansion of the oil as the oil temperature varies with operating conditions thereby

eliminating the need for bulky overflow tank.
