HVA 1500/50 User Manual V2.0
To ensure safe operation and to keep the operator and the product safe,
THE INFORMATION, CAUTIONS, AND WARNINGS IN THIS
MANUAL MUST BE HEEDED.
WARNING – WARNING STATEMENTS AND SYMBOLS IDENTIFY
CONDITIONS OR PRACTICES THAT COULD RESULT IN INJURY OR
LOSS OF LIFE.
CAUTION – CAUTION STATEMENTS AND SYMBOLS IDENTIFY
CONDITIONS OR PRACTICES THAT COULD RESULT IN DAMAGE TO
THIS PRODUCT OR OTHER PROPERTY.
REVIEW THE FOLLOWING SAFETY PRECAUTIONS TO AVOID INJURY AND
PREVENT DAMAGE TO THIS PRODUCT OR ANY PRODUCTS CONNECTED
TO IT. TO AVOID POTENTIAL HAZARD, USE THIS PRODUCT ONLY AS
SPECIFIED.
• Only qualied personnel should operate and make connections to this
unit.
• All connections including removal of any connections from the High
Voltage Output Connector must be done with the unit OFF and discon-
nected from the AC line source.
• To avoid shock hazard, electrocution, or re, observe all ratings and
markings on the product. Consult the User’s Manual for further safety
information before making connections to the product.
The High Voltage Amplier HVA 1500/50 generates voltages up to 1500V.
These voltages are present inside the unit and at the rear panel output
connectors and are a danger to life if used improperly.
Make sure that attached cables are electrically and mechanically NOT
defective. Replace cables only with the high voltage amplier switched o.
Before switching the high voltage amplier on, make sure that all cables are
connected to the corresponding socket of the load.

Before removing the cables from the load, switch o the amplier and wait
at least 10 minutes until the load capacitors are discharged.
Never operate the high voltage amplier if any housing part of the unit is
defective or removed.
Do not open the high voltage unit. Only qualied personnel may open the
unit.
Warning!
HAZARDOUS VOLTAGES UP TO 1500V ARE
PRESENT AT THE HIGH VOLTAGE AMPLIFIER’s
OUTPUT.
TAKE APPROPRIATE PRECAUTIONS DURING
MEASUREMENT PROCEDURES.
BEFORE TURNING ON THE AMPLIFIER, REMOVE
HANDS AND ALL TEST EQUIPMENT FROM THE
LOAD AND CONNECTED CABLES!!

HVA 1500/50 User Manual V2.0
The HVA1500/50 is a single channel, high voltage power amplier. The
power amplier 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 amplier 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 oset 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 amplier 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 amplier 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 amplier unit
should be veried upon receipt. Make sure that no cable is electrically
and mechanically defective. If the unit is damaged in transit, or fails to
meet the specications upon receipt, notify the carrier and the sales oce
immediately. Retain the shipping carton and padding material for the
carrier’s inspection. The sales oce will arrange for replacement or repair
of your unit without waiting for claim settlement against the carrier. Before
returning the high voltage amplier for any reason, notify the sales oce of
the diculty encountered. They will send shipping instructions.
3.3 INSTALLation
The AC power supplied to the amplier 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 amplier 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.
