FF Range of Floating Filament Modules

Output 7.5v at 5A ISOLATION TO 30kV

Applications (now up to 30 kV)

Mass Spectrometers
Electron Guns
Electron Gun Evaporators
X-Ray Tube Filaments
Power input & control at ground potential

These power supplies use the proven power oscillator from the standard 100 watt HW series and are intended to power ion gun, electron gun & X-ray filaments of up to 1.5 ohm (including cable resistance). The filaments can be isolated from ground by up to 30 kV, while power input & all controls remain at ground potential.

Higher isolation voltages are also possible. Please consult the factory for more details.


Electrical Specification
Input voltage (at ground potential):
24V d.c. ±0.5V at 3A maximum.

Output current:
0.8A to 5A at up to +7.5 volt d.c.

Control:
0 to +10V gives 0 to 5A, or by internal or external potentiometer

Ripple:
Less than 200 mV peak to peak, ripple frequency 50 kHz.

Load regulation:
Less than 1% for 10% change in filament resistance. The output impedance of the power supply is electronically controlled to maintain the filament temperature as the filament changes

Line regulation:
Less than 1% for 0.5V change in 24V.

Temperature co-efficient:
0.1% per °C.

Current monitor (pin 3):
0 to 10V represents 0 to 5A (accuracy ±5 %, source resistance 10 kohm).

Inhibit (pin 8):
Low = on, high or O/C = off.

Operating temperature:
0 °C to +45 °C.





Mechanical Specification
Size:
230 x 120 x 60 mm (5kV, 15kV & 30kV isolation)

Output cables:
Length 1 metre approx

Pin connections:
As standard HP series with current monitor on pin 3 and on/off on pin 8.
