AE Techron’s 7136 is a high-voltage, 900-VA, four-quadrant, AC and DC amplifier that provides exceptional versatility and value. Compact size, user configurability, DC-Max™ topology, and AE Techron toughness makes the 7136 the ideal lab partner for DO-160 Section 16 AC with DC offset testing, or any application where more voltage or current is needed than is available from the signal source.

Compact Power

The 7136 weighs just 40 pounds and fits into a 2U rack space, but still can output up to 900 watts RMS continuous. This makes the 7136 a great choice when size or portability are important selection criteria.


Front panel user controls give the 7136 a wide range of possible uses; gain, maximum current, and DC offset can be fixed or infinetely varied. The choice of AC or DC coupling makes it suitable both for DC applications and for driving objects like coupling transformers or piezo elements that shouldn’t see DC. All controls can be turned off when only a durable, high-current amplifier or DC source is needed. Or each function can be individually enabled to provide the unique set of capabilities needed at the moment.

The 7136 can produce a DC output without an input signal. DC output is independent of input signal and amplifier gain. This DC capability, when combined with an input signal from a function generator, creates a versatile DC source with high-speed ripple and dropout capabilities.


7136 is built with our new DC-Max topology. Amplifiers with DC-Max have long term DC power that is more than 40% greater than traditional designs. This increased DC performance better matches the power requirements found in DC conducted immunity and PSRR testing.

AE Techron Toughness

The 7136 is compact in size, but it is designed using the same conservative design rules and protection systems that have made AE Techron amplifiers the toughest audio bandwidth amplifiers available.


AC Output

Note: Testing performed into resistive loads as specified. Performance reported is typical into the specified load up to 20 kHz frequency levels. Performance may be affected when operating into highly reactive loads or above 20 kHz, reducing maximum voltage, current and power output.
