2 Overview
This manual covers the following models:
HAR12A 12-channel high voltage amplifier
HAR12 12-channel high voltage amplifier mainframe (BNC output connectors)
HAR12S 12-channel high voltage amplifier mainframe (SHV output connectors)
HAR2 2-channel high voltage amplifier mainframe (SHV output connectors)
HAR2-W 2-channel high voltage amplifier mainframe (SHV output connectors)
HA05B2 single channel high voltage amplifier module family
3 Description
The high voltage amplifier HAR12 is a 3U high 19" rack-mountable unit. Up to twelve
independent channels provide output voltages in the range of –500V to +500V at a load current
of ±2mA each. The gain is 50 and the input voltage range is ±10 V. The channels consist of
HA05B2 amplifier modules.
The amplifier channels are characterized by high accuracy, very high stability and very low
noise. The device can thus be used as a multi channel reference voltage source.
Both the output voltage and the load current of each channel can be displayed on two DVMs.
A rotary switch (CHANNEL) is provided for selection of the channel to be measured.
The output voltages of each channel can be controlled by a control voltage (IN) or by a 10-turn
potentiometer (SETPOINT). Each channel is equipped with a voltage monitor output, current
monitor output and inhibit input.
All amplifier outputs are protected against overload, short circuit, and transient overvoltage.
The HAR2/HAR2-W mainframes accommodate up to two amplifier channels.
HAR2 is a table top unit, HAR2-W is a wall-mount type.
The HAR12 models are supplied by mains voltage. The HAR2 models are supplied by 24VDC

3.2 Control Voltage Input
The control voltage input (IN) is connected to a differential amplifier to
suppress common mode voltages between the external signal source and
the amplifier. Two jumpers (W1, W2) are provided on each amplifier
module HA05B2 in order to adapt the control voltage input to the signal
source.
W1 connects the input signal reference via 10 to the amplifier signal
ground. W2 adjusts the amplifier gain to the output impedance of the
signal source.

or floating signal source
Default
2-3 Common mode voltage / Noise 1...4 VRMS
W2
1-2 Output impedance of signal source <1 Default
2-3 Output impedance of signal source 50
Alternatively, the control voltage can be generated by means of a 10-
turn potentiometer (SETPOINT). The potentiometer supplies –10 V at the
CCW end position (0) and +10 V at the CW end position (10). Zero
position is at 5. Switching between internal and external control voltage
is achieved by a front panel switch (MAN / REM).
3.3 Measuring Circuits / Monitor Outputs
Two monitor outputs (V-MON / I-MON) provide actual values of output voltage and output
current, both of which are normalized to ±10 V. The monitor outputs receive their signal through
a compensated voltage divider. Current measurement takes place differentially across a sense
resistor in the output line. Due to differential measurement, a certain drift of the measured
output current over temperature and output voltage is inevitable (refer to technical
specifications).
If the INHIB-input is active, then an appreciable current flows through the sense resistor. This
current is shown by I-MON even though it does not flow from the output (The current flows into
the inhibit semiconductor switch). This value is masked out in the signal to the DVM.
The monitor outputs are buffered and short-circuit-proof. They can drive capacitive loads
(coaxial cable). They are not designed to drive terminated cables (50/75 ), and they should
not be short circuited during normal operation. Load impedance 4 k.

3.4 INHIBIT
Each high voltage amplifier channel can be remotely switched off through the INHIB input. The
input is TTL-compatible. A LOW-signal turns on the amplifier. In case of open input or HIGH-
signal, the amplifier is turned off. For manual operation, a 50 : BNC-termination resistor can be
used to statically turn the amplifier channel on.
The Inhibit-signal drives a semiconductor switch, short-circuiting the output (approx. 100 )
within microseconds. The switch conducts independently of the internal supply voltage, even
after the device is switched-off.
The INHIB input is not suitable to achieve a safe state at the amplifier output. It must not be
used for safety relevant purposes.
3.5 Loading Conditions
The amplifiers are designed to drive any combination of resistive and capacitive loads.
Full output voltage is available for resistive loads 250 k. When driving capacitive loads the
reactive current must be taken into consideration. This current into the load capacitance
depends on the capacitance value and the slew-rate: iCL = CL * dv / dt.
The effective load capacitance consists of connected load capacitance, the capacitance of the
output cable, and the capacitance internal to the amplifier. If the output current exceeds the
peak current capability of the amplifier module (refer to the specifications), the output voltage
will become distorted.
The achievable large-signal bandwidth strongly depends on the capacitance of the connected
load.
Particularly with regard to the high speed versions of the amplifier modules, the cable
capacitance may become the dominant part of load capacitance. One meter of typical coaxial
cable has a capacitance of about 100 pF.
Large capacitive loads driven by high frequency signals may result in a DC-offset superimposed
on the output voltage. This occurs if the final value of the desired output voltage can not be
reached periodically.
No damage to the amplifier modules will result from the different conditions mentioned.
