DESCRIPTION

Grid:
Bipolar +150V 20mA, -200V 100µA.

The Model XRF50-503 is a modular X-ray power supply for gridded
tubes in industrial and scientific analytical applications. Powered
from 24V DC input, the XRF50-503 provides a floating filament and the
required floating grid circuitry to enable fast control of a gridded tube.
All setting and monitoring is carried out by a detailed RS232 command
set.
If the version you require is not on this datasheet then please enquire
as we produce many custom versions for specific requirements.
