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.

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.
