Switch-Mode Amplifier 8700
The AE Techron 8700 Series consists of high-power switch-mode amplifiers optimized for demanding laboratory, industrial, and EMC conducted immunity applications. These units excel in DC and low-frequency operations, providing a wide bandwidth that reaches up to 250 kHz. Their architecture is specifically designed to provide high efficiency without compromising the precision required for dynamic testing environments. Constructed with a four-quadrant operation design, these amplifiers can both source and sink power, ensuring they remain stable when driving complex inductive or capacitive loads. The series features field-selectable controlled-voltage or controlled-current modes, allowing operators to tailor the amplifier's performance to the specific requirements of the test load. This versatility is supported by a high slew rate, making the 8700 Series ideal for generating the fast transient waveforms necessary for modern immunity standards. The 8700 Series is highly scalable, offering models that range from compact bench-top units to large-scale high-power cabinet systems. Available models include the 8704, which provides 60A RMS on single-phase power, as well as the 8708 and 8712, which provide 120A and 180A RMS respectively on three-phase power. With multiple voltage input options including 208V and 400V configurations, these amplifiers can be integrated into a wide variety of global power environments.Wide Frequency Range
