The A1110-40-QE is a linear, extreme broadband precision power amplifier. It is ideally suited for applications that require fast signal processing at high power. The A1110-40-QE can be operated either as voltage amplifier or as current amplifier. In current amplifier mode it provides constant, frequency-independent output current e.g. for inductive loads.

There are three operating voltages available for optional selection: high-voltage / low-current or low-volt / high-current. Particularly with low impedance load the operating voltage can be reduced to 1/3 of the value, which entails a corresponding reduction of dissipation power. Output voltage and output current can be optionally limited. Moreover, low impedance signal outputs are available as monitoring outputs.

The device is equipped with a low-noise, temperature-controlled fan. In addition to over temperature shut-down, a feature for dissipation power calculation and current monitoring ensures perfect overload and short-circuit protection. An interlock ensures optional operation as remote-controlled safety system.

Operation is performed via the control elements on the front panel of the amplifier and the graphical user interface on a PC, which is connected to the amplifier by means of the USB interface (the required software is included in the scope of delivery). If higher output voltages or higher output currents are needed, configurations with several A1110-40-QE devices connected in series or in parallel are possible.
