4-quadrant
voltage and current amplifier
DC-1 MHz | 60 V/μs | 1000 W (source)
1 Product Description
The A1110-40-QE-70-16
is a linear, extreme-broadband, precision power amplifier with optimized voltage
ranges for automotive wiring system simulation.
The A1110-40-QE-70-16
can be operated as a voltage amplifier or current amplifier. The current amplifier
offers a constant, frequency-invariant output current for inductive loads.
Three
optional operating voltages per polarity are available for high-voltage/low-current
or low- voltage/high-current applications. The voltage switch-over can be implemented
optionally as manual or automatic. Especially in case of very low-impedance loads,
the operating voltage can be reduced to 1/10 which is associated with a corresponding
reduction of the power loss.
Output
voltage and output current can be limited and observed on low-impedance monitor
outputs.
The device
is equipped with a temperature-controlled, quietly-running fan. As well as an over-
temperature protection, a power-loss calculation and an
absolute-current monitoring guarantees perfect short-circuit and overload protection.
An interlock
offers the possibility of a remote-controlled security system.
The device
can be operated by using elements on the front panel. Additionally the device can be controlled with the supplied A1110 Control Software via an USB
connection.

5 Current Amplifier
In current
control mode, the A1110-40-QE-70-16 behaves like a voltage-controlled current source
and delivers a nearly frequency-independent constant load current to an inductive
load.

The selection
is made by our A1110-QE-Control software. Please also note the corresponding recommended
current measuring range.
If none
of the above compensation networks is suitable for your application, please order
your amplifier with Option-01: Custom Current Amplifier. Our engineers will design
a custom compensation network specific for your needs. You can add additional networks
to your amplifier. Up to six customs networks are possible as existing ones can
be removed.
We would
be pleased to assist you in the realization of a compensation network for your application.
