Linear Amplifiers
Our linear amplifiers offer DC-1MHz with fast rise times and a very low noise floor. They are excellent at driving resistive loads and are used in for various applications in research, university labs, EMC, imaging, and magnetics.

Switch-mode Amplifiers
Our switch-mode amplifiers have the lowest noise floor on the market, while providing high bandwidth at a very low cost per watt. They are excellent at driving inductive and capacitive loads, reusing the returned power to increase apparent power as much as 4X greater than the rated power.

Gradient Amplifiers
AE Techron is an industry pioneer in MRI. Our gradient amplifiers are high-power, DC-enabled linear amplifiers with an integrated power supply. They offer a wide bandwidth, very low noise, and exceptional control of drift and distortion.

Looking for a particular amplifier?
Search the AE Techron product database to find the amplifier to fit your specific needs.

RLY Amplifiers
Our RLY amplifiers are created to meet the demanding requirements of the power utility industry. With models capable of outputting up to 200 amperes peak current, these amplifiers are powerful enough to put protection relays, fuses and other critical components through a full range of tests. Low noise floor, low distortion and minimal phase error make these amplifiers ideal for power grid modeling.

EMC Test Systems
We provide comprehensive solutions for power quality, conducted immunity, and induced susceptibility testing for the EMC industry.

Other Products from AE Techron
We produce a wide range of products that meet the requirements for specific standards testing. From a chattering relay to three different coupling transformers, we offer solutions for you to build your own custom test system.

Conversion Calculators
Formulas, equations, and calculation tools for most compliance engineering applications.

Ohm’s Law
Ohm's Law is valid for circuits that contain only resistive elements (no capacitors or inductors). Ohm's Law is true for voltage and current (DC) or (AC).

Effective Impedance
Effective Impedance is the DC resistance plus the additional apparent impedance caused by inductance and capacitance at a specified frequency.

Voltage to dB Converter
This function converts the linear relationship between two voltages or powers into decibels, and decibels in power or voltage gain or attenuation.

Voltage Dropped & Power Dissipated Across a Series Resistor
Power dissipation is a measure of how much power is converted into heat in a circuit due to inefficiencies.

Compliance Voltage
Compliance voltage represents the maximum voltage a current source will reach as it attempts to produce the desired current at the desired rate of change.

Decibel Conversion
Converts between decibels, voltage (or current) gain, and power gain.

Watts to Joules Conversion
Convert watts to joules by entering the power in watts and time in seconds using this easy calculator.
