Features:
Compact size and light weight
Efficiency approx. 90%
For units from 12.5kV nominal
voltage on, all HV compo-
nents are moulded in
(removable) silicon
Short-circuit & flashover proof
Unlimited operation with rated
current in a short-circuit con-
dition
Unlimited operation with rated
power
Voltage and current regulation
with automatic sharp transi-
tion, control modes indicated
by LEDs
Adjustable overvoltage pro-
tection (limitation of set value)
4½ digit DVM's for voltage
and current for all models
Voltage and current setting by
means of 10-turn potentiome-
ters with precision scale; the
adjusting knob can be locked
Indication of set point values
by means of button for switch-
over 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
Function:
In principle, the rectified line
voltage drives a square wave
generator of fixed frequency,
whose AC voltage is trans-
formed, rectified and filtered,
producing the output voltage.
For regulation, the square wave
voltage is pulse width modulat-
ed.
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.
Design:
½19" or 19" table-top case
(depending on output voltage
and power).
19" Rack-adapters for mount-
ing into a 19" rack are availa-
ble 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 con-
nected to earth. If required,
the "0V" terminal can be
made floating against earth
up to ± 300V. A polarity re-
versal switch is optionally
available.
Output terminals:
All output terminals are locat-
ed 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.
