8000 Series High Voltage DC Power Supply500V to 70kV

If you would like to learn more about this product: Please Contact Us

 The Genvolt 8000 series, High Voltage DC Power Supply, is a rugged modularised range of AC input DC High Voltage units that are designed to operate from a universal mains input from 85VAC to 256VAC 50/60Hz. Power Output options are available from 500V to 70kV at 120W and 49kV to 70kV at 200W. 

HVPS Features

The HVPS have an active boost-style Power Factor Correction front end – i.e. an active rectifier. This offers a very low harmonic distortion at mains frequencies with a power factor of up to 0.99.
The modules have a FIXED polarity output which should be specified at the time ordering using the “Model Finder” table.

Operation And Protection

They operate in both Voltage Control and Current Control modes with fast active crossover between the modes.

Integral protection against output short circuits or arcs over temperature and output overvoltage allow for operation in the most demanding environments.

The control signal is NOT a safety interlock and must NOT be used for a protection system from high voltage generation for safety purposes.

Standard Features, as fitted at the factory

Control Logic level for high voltage enable/disable.
Overvoltage Protection Overvoltage conditions can be caused by excessive input program signal. If an overvoltage condition is detected, the power supply is latched off until input power is reset.
PS Fault Condition A PS fault indicator and a PS fault output on J1, indicate an OVP or a regulation error.
PF and Universal Input The input voltage of the 8000 can operate within the range from 85VAC to 265VAC. The power factor is actively corrected across the entire range and is better than 0.99 at full load.
Internal EMI Filter An internal EMI filter and fuse provide protection against line voltage surges and power supply faults

Remote Operating Features

Remote Programming Allows remote adjustment of the output voltage and current, via an external voltage source.   
Remote Monitor Allows remote monitoring of the output voltage and current.
High Voltage Enable/Disable Allows remote ON/OFF control of the high voltage.
+10VDC Reference A +10VDC is provided for remote programming via a potentiometer or voltage divider.
