Description:
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.
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.
| AC Input voltage range | 85VAC to 256VAC, 47 – 63 Hz |
|---|---|
| Power Factor | Full Load 0.99 Non-Load 0.98 |
| Output Polarity | +ve or –ve (Please specify when ordering) |
| Voltage Load Regulation | 0.01% of full voltage for a no load to a full load change |
| Voltage Line Regulation | +/- 0.005% of full voltage over the specified input voltage range |
| Current Load Regulation | 0.01% from 0V to full voltage |
| Current Line Regulation | +/- 0.01% of full current over the specified input voltage range per 8 hours after |
| Voltage Ripple: | 0.1% p-p of output voltage |
| Current Stability | 0.02% per 8hrs after ½hr warm up |
| Temperature Coefficient | 100 ppm per ˚C |
| Temperature | Operating 0˚C to 45˚C Storage -20˚C to +85˚C |
| Interlock | Open Interlock will shut down unit |
| Circuit Protection | Overvoltage, Overcurrent, Arcing and Over temperature |
| Relative Humidity | Non condensing 95% |
The control signal is NOT a safety interlock and must NOT be used for a protection system from high voltage generation for safety purposes.
| 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 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. |
| Weight | Model specific, approximately 3Kgs |
|---|---|
| Dimensions | 95.25mm (H) x 127mm (W) x 279.4mm (D) |
| Power Input Connector | IEC320 with mating connector x 2 Metres |
| HV Output Connector | Proprietary HV Connector |
| Control Interface Connector | 15 pin ‘D’ connector (Male) |
