V 0913
High voltage power supplies thyristor regulated
Series HYN from 3,5 kV to 20 kV / 21kW to 50 kW
Features:
 Simple construction
 Extremely robust
 High efficiency
 Short circuit proof and unlim-
ited operation with full current
in short circuit condition
 Voltage and current regulation
with automatic and sharp
transition; control modes
indicated by LEDs
 Voltage and current setting
with 10-turn potentiometers
with precision scale; the ad-
justing knob can be locked
 Limitation of inrush current on
switching on
 Suitable also for inductive and
capacitive loads
 Interlock loop to monitor the
external load and internal loop
as a standard
 Elapsed-hour meter as a
standard
Function:
The mains voltage is trans-
formed to high voltage potential.
Either on the primary side or on
the secondary side, a phase
cutting circuit with thyristors is
installed. The rectified voltage is
smoothed by a LC - filter.
Design:
 Depending on voltage and
power the units are built as
single or double 19" cabinets
of various height. The side
covers are detachable, the
rear door is lockable.
 All cabinets are equipped
with fork-lift-compatible
plinths and removable crane-
eyes.
 Single 19"- cabinets up to
38U are easily transportable
by fork-lift.
 Cooling is carried out via
convection or built-in fans,
with the air being exhausted
(depending upon type) either
via the rear or the top.
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. A polarity
reversal switch is optionally
available.
 Output terminals:
All output terminals are locat-
ed at the rear side of the
cabinet. For Output current
up to 10A high voltage con-
nectors with the appropriate
dielectric strength are in-
stalled. Mating connectors
are delivered with the power
supply.
