A123 - 1
1 Introduction
1.1 Device Description
The A123 - 1 is a linear, extremely wideband precision power amplifier. It is ideal for all
applications that require fast changing signals at any purely resistive and complex loads.
The A123 - 1 has two summable inputs with 5 Ω and 1 kΩ input resistance; the 5 Ω input
makes it the ideal downstream equipment for conventional function generators.
Two optional operating voltages are available for high-voltage/low-current or low-voltage/high-
current applications. Especially in case of very low-impedance loads, choosing the low operating
voltage leads to a considerable reduction of the power loss and a higher output current. If higher
output voltages are required, the preamplifier output ( Bridge Out ) allows a simple set-up of a
bridge circuit with a second A123 - 1 for doubling the output voltage
The device is equipped with a temperature-controlled, low noise fan. Additionally an over-
temperature protection, a power-loss calculation and an absolute-current monitoring guarantee
perfect short-circuit and overload protection.
In addition to the operating elements on the front panel, the amplifier is fully remote controllable via
the USB port or LAN interface, using a simple byte protocol.
If even higher output voltages or higher output currents are required, configurations with series or
parallel connections of several A123 - 1 are possible.

2.2 General Safety Advice
The following general safety instructions must be observed during the use of this device.
Disregarding this advice or specific warnings in this manual will violate safety standards in the
intended uses of this equipment.
The manufacturer is not responsible for consequences resulting from disregarding the advice and
warnings.
Electrical voltage – Danger of electric shock
Parts under voltage:
Always cover all parts under voltage that inevitably arise during operation.
Touching of cables, sockets and plugs:
Never touch the contacts of cables, sockets or plugs directly after disconnecting them, as there is a
risk of electric shock.
Contact between amplifier outputs and PE:
Touching an ampli er output and PE at the same time can result in a life threatening electric shock.
Earth the device:
The device ful lls the requirements for protection class I. To avoid the risk of electric shock, the
device housing must be earthed and therefore always operate the device via the supplied three-
core power cable with protective conductor. The mains cable may only be plugged into a grounded
socket with a protective earth contact. An interruption of the protective earth conductor inside or
outside the device reduces the safety of the device and is prohibited.
Safety Regulations for the work with electrical equipment:
- Disconnect mains!
- Prevent reconnection!
- Test for absence of harmful voltages!
- Ground and short circuits!
- Cover or close of nearby live parts!
Devices with a heavy current connection:
Devices with a heavy current connection may only be operated via a 4-pole RCD with ≤40 ms at 5 x
IΔn. If it is not possible to install the RCD in the building installation, then our device must be
connected to the mains supply via a mobile distributor with the appropriate RCD.
Do not open the housing:
Covers must not be removed by the operating personnel. Maintenance and repair work is reserved
exclusively for quali ed service personnel.

Important notes
The device must be used exclusively for its intended purpose.
The device is only approved for operation within the connected loads speci ed on the type label.
Do not insert any mechanical parts, especially metal parts, into the device through the ventilation
slots.
Protect the unit from moisture, humidity and condensation. Avoid using liquids near the device.
Never connect loads while the ampli er outputs are switched on.
Operate the device exclusively on the public power supply system (no generators/UPS).
To avoid personal injury and property damage, make sure that the equipment and components
used in the test are not overloaded. Read all operating instructions for the devices used thoroughly
and ensure that all defined device limits are adhered to. If there are doubts about the suitability of
the devices for the test to be performed, contact the manufacturer of the device.
2.3 Intended Use
2.3.1 Hardware
The device is intended exclusively for use as an LF power amplifier. Typical applications are the
operation as voltage amplifier on passive loads. Active loads are only permitted under certain
conditions in agreement with the manufacturer.
