Before removing the cables from the load, switch o the amplier and wait
at least 10 minutes until the load capacitors are discharged.
Never operate the high voltage amplier if any housing part of the unit is
defective or removed.
Do not open the high voltage unit. Only qualied personnel may open the
unit.
Warning!
HAZARDOUS VOLTAGES UP TO 1500V ARE
PRESENT AT THE HIGH VOLTAGE AMPLIFIER’s

HVA 1500/50 User Manual V2.0
The HVA1500/50 is a single channel, high voltage power amplier. The
power amplier is capable of delivering an output voltage in the range of
-500 V to +1500 V with an output current of up to 50 mA DC.
The amplier provides a large signal bandwidth of DC to 10 kHz depending
on the load capacitance and has a gain of 200 V/V.
Two independent signal inputs are provided, a wave generator input and
an audio signal input which can be selected by a rotary switch. The wave
generator input accepts signals in the range of -2.5 V to +7.5 V at a
frequency of 0 Hz to 10 kHz.
The audio signal input accepts audio signals in the range of 0.2 V to 3 V AC
at a frequency of 10 Hz to 10 kHz. Two potentiometers are also provided to
adjust the gain and the oset of the audio signal.
The monitoring circuitry allows output voltage and output current
monitoring. Both monitoring signals are near ground potential, i.e. not
hazardous, low voltages.
Two LEDs indicate the states of the output voltage/current. A LED for
“HV On” and a LED for “Limit”. The LED “HV On” illuminates if the output
voltage is enabled by a rotary switch or by an interlock signal.
The LED “Limit” illuminates if the output voltage/current exceeds the limits.
The interlock circuitry allows switching o and on the high voltage by an
external signal.

HVA 1500/50 User Manual V2.0
This section provides information for incoming inspection, damage claims,
shipping, and installation of the HVA1500/50.
3.1 What comes with thE HVA1500/50
The HVA1500/50 package contains the following items:
• Single channel high voltage amplier unit HVA 1500/50,
• Line voltage cord,
• High voltage cable with an SHV plug,
• 3-pin interlock connector,
• User Manual.
3.2 incoming inspection
The high voltage amplier unit should be inspected for damage, scratches,
dents, or other defects. Also the cushioning materials should be checked
for sign of severe stress. The electrical performance of the amplier unit
should be veried upon receipt. Make sure that no cable is electrically
and mechanically defective. If the unit is damaged in transit, or fails to
meet the specications upon receipt, notify the carrier and the sales oce
immediately. Retain the shipping carton and padding material for the
carrier’s inspection. The sales oce will arrange for replacement or repair
of your unit without waiting for claim settlement against the carrier. Before
returning the high voltage amplier for any reason, notify the sales oce of
the diculty encountered. They will send shipping instructions.
3.3 INSTALLation
The AC power supplied to the amplier unit should be 90 to 264 VAC, 47 to
63Hz, single phase. Two 2-ampere slow blow fuses of 1.6A are used.
For safety reasons, the power supply must be grounded through the AC
power cord. When operating from ungrounded power sources, a secondary
grounding method is mandatory. Before operation, make sure that the
output cable of the amplier unit is connected to the load.
The cooling of the control unit is provided by convection. The location of the
unit must ensure adequate air circulation.

5.3 Operational requirements
Before making any connections, make sure that the amplier unit is turned
o.
• Connect the amplier unit to the mains.
• Connect the high voltage output connector of the amplier to the
load.
• Connect the interlock cable to the interlock connector of the
amplier unit.
• Connect a ground cable from the load to the GND screw on the rear
panel of the amplier unit if necessary.
• Set the output control switch on the front panel to “O” before
switching the power on.
5.4 operating mode
Prior to the operation, the amplier should be warmed up 5 minutes in
order to achieve the nominal stability of the amplier.
• Set the output control switch to “O”.
• Select the required input “WG Input” or “Audio Signal Input” with the
rotary switch on the front panel.
• Make sure the interlock signal is activated at the rear panel socket
“Interlock”.
• Apply a signal to the input selected.
• Turn on the output voltage by setting the output control switch to
“On”. The indicator LED “HV On” will go on. If not, check the interlock
signal at the rear panel socket “Interlock”.
• Check if output voltage is present at the output by monitoring the
monitor signal “Voltage” or “Current” with an oscilloscope.
• Should the indicator LED “Limit” go on, lower the input signal amplitude
or signal frequency. In case of an audio signal, the gain or oset
potentiometer can also be used to control the limit condition.
• Turn o the unit by switching o the power.
