Fonte de Alimentação CC de Alta Tensão Fug Série Professional HCP

HIGH VOLTAGE POWER SUPPLIES - Switch Mode Regulation

Series HCP from 3.5kV to 300kV / 14W to 15kW

In principle, the rectified line voltage drives a square wave generator of fixed frequency, whose AC voltage is transformed, rectified and filtered, producing the output voltage. For regulation, the square wave voltage is pulse width modulated. A low residual ripple of the output voltage, together with a high stability, high regulation speed and a low stored energy are all achieved by virtue of the high switching frequency.

FEATURES:

- Compact size and light weight

- Efficiency approx. 90%

- For units from 12.5kV nominal voltage on, all HV components are moulded in (removable) silicon

- Short-circuit & flashover proof

- Unlimited operation with rated current in a short-circuit condition

- Unlimited operation with rated power

- Voltage and current regulation with automatic sharp transition, control modes indicated by LEDs

- Adjustable overvoltage protection (limitation of set value)

- 4½ digit DVM‘s for voltage and current for all models

- Voltage and current setting by means of 10-turn potentiometers with precision scale; the adjusting knob can be locked

- Indication of set point values by means of button for switchover of the displays

- Set point adjustment possible with locked output, release of output voltage by means of „ON“ / „OFF“ switch

- Suitable also for inductive and capacitive loads

- Suitable for photomultipliers

DESIGN:

- ½19" or 19" table-top case (depending on output voltage and power).

- 19" Rack-adapters for mounting into a 19" rack are available as accessory.

OUTPUT:

- Output isolation: The required output polarity must be stated with the order. The requested output polarity will then be available at the HV connector and the “0V” terminal will be firmly connected to earth. If required, the „0V“ terminal can be made floating against earth up to ± 300V. A polarity reversal switch is optionally available.

- Output terminals: All output terminals are located at the rear side of the unit. High voltage connectors with the appropriate dielectric strength are delivered with the power supply. For nominal voltage of 65kV and higher the HV- plug will be delivered ready mounted to 3m cable. 

TECHNICAL DATA:

- Mains connection:

>> Up to 1400W nominal power: 230V ±10% 47Hz to 63Hz

>> For 2800W and higher: 400V ±10% 47Hz to 63Hz, three-phase

- Ambient temperature:  0°C to +40°C

The following data applies for voltage and current regulation, and refers to the rated value (unless otherwise stated):

- Setting range: from approx. 0,1% to 100%

- Setting resolution: ±1 x 10-4

- Residual ripple (0-10MHz): <1 x 10-4pp + 50mVpp, typ. 5 x 10-5pp

- Recovery time:

>> Voltage control: <1ms for load changes from 10% to 100% or from 100% to 10%

>> Current control: <10ms for load changes causing an output change of less than 10% of the rated voltage

- Setting time at nominal load: <500ms for changes of the output voltage from 10% to 90% or 90% to 10%

- Discharge time constant for output without load: approx. 2sec. to 10sec., depending on type

- Deviation:

>> For ±10% mains voltage variation: <± 1 x 10-5

>> For no load / full load: <2 x 10-4

>> Over 8 hours under constant conditions: <±1 x 10-4

>> Within the temperature range: <±1,5 x 10-4/K

POSSIBLE OPTIONS:

- Coarse/fine-potentiometers (99% / 1%) for more accurate adjustment of voltage and / or current

- Analog programming

- Analog programming, floating

- Computer interfaces - IEEE 488, RS 232, RS 422, Profibus DP, USB, LAN (more on request)

- Electronically controlled polarity reversal switch (Up to 35kV remotely controllable when ordered with a programming or interface, for higher voltages, on request). Please specify the output polarity, when ordering without polarity reversal switch.

- Lower ripple

- Higher stability

- Lower stored energy

- Power limitation
