Fonte de Alimentação Euro-Cassette Fug Série Professional HCE Cassette

HIGH VOLTAGE POWER SUPPLIES - Switch mode regulation as Cassette

Series HCE from 125 V to 35 kV / 7 W to 350 W

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.

FEATURES:

- Compact size

- Light-weight

- For units from 6.5kV nominal voltage on, all HV components are moulded in (removable) silicon

- Short circuit and flashover proof

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

- Unlimited operation with rated power

- Voltage or current regulation with automatic transition.

- Control mode indicated by LEDs

- Screwdriver adjustment of voltage and current on the front panel

- Standard analog programming plus HV ON/OFF input and monitor outputs

- Measuring terminals for voltage and current monitors on the front panel

- Suitable for use with capacitive loads

- Suitable for use with photomultipliers

OPTION: Ten turn potentiometer for voltage on the front panel.

DESIGN:

- EURO-cassette design. Width depending on type.

- 19“ frames are available as an option.

OUTPUT:

- Output isolation: The polarity is positive or negative and has to be indicated with the order. The „0V“ - terminal of the output is connected to earth but may be disconnected as needed. When disconnected, the „0V“ (earthy) terminal may float with respect to earth up to ±125V.

- Output terminals: Outputs are located on the rear of the units. For units up to 650V nominal voltage, the output is on 4mm safety connectors. From 1250V nominal voltage on, HV-connectors are provided. The mating HV- connectors are delivered with the unit.

TECHNICAL DATA:

- Mains connection: 230V ±10% 47Hz to 63Hz

- 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: <200ms for changes of the output voltage from 10% to 90% or 90% to 10%

- Discharge time constant for output without load: approx. 0,5sec. to 5sec., 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

Voltage and current adjustment by screwdriver or via analog programming
