HiTek Power has added an
RS232-controlled variant to its XRG70 series of compact high voltage power
supplies. The XRG70-703 RS232 offers an output voltage range of 0 to 70 kV at 0
to 1 mA and maximum output power of 700 W. The unit also incorporates a 5.5 VDC,
3.5 A grounded filament power supply.
The new supply is a member
of HiTek Power’s grounded-filament range of products designed for use in
grounded-cathode applications. The filament supply is automatically controlled
by the integral beam-current loop control and the power stage uses a
current-fed resonant push-pull converter to give high efficiency while ensuring
reliable operation.
The combination of
surface-mount technology, high-voltage stress control, and innovative packaging
techniques ensures a compact, but highly reliable product. The XRG70-703 RS232
measures 140 mm wide × 73 mm high × 233 mm deep and weighs only 3.3 kg.
